House Martell

"'Unbowed, unbent, unbroken'. The words of House Martell. A promise to our enemies, and a challenge to our lovers."

- Oberyn Martell

House Martell of Sunspear is a legally extinct Great House of Westeros. It ruled the peninsula of Dorne in the far south of the continent from their castle Sunspear. Though loyal to the Iron Throne, the Martells were never conquered by the Targaryens and pursued a more isolated role in wider political events since Robert's Rebellion.

House Martell's sigil is a red sun pierced by a golden spear, on an orange field, a combination of the original Martell sigil - a yellow spear - and the emblem of Princess Nymeria - a red sun - to symbolize the marriage of the warrior-queen to Mors Martell. Their house words are "Unbowed, Unbent, Unbroken."

With the assassinations of Prince Doran Martell and his only heir, Prince Trystane, by Ellaria Sand and the three eldest Sand Snakes, House Martell is legally extinct, although the Sand Snakes carry Martell blood through their father Oberyn Martell. The Sand Snakes also continue to use the Martell sigil to represent themselves and Dorne.

Under the leadership of Ellaria Sand and the Sand Snakes, the forces of House Martell and Dorne have aligned to support the cause of Daenerys Targaryen against House Lannister after they declared war against them.

Since the deaths of the older Sand Snakes and Ellaria's imprisonment in King's Landing, House Martell's future is uncertain as five Sand Snakes still live.

Background
House Martell started out as local kings in Dorne, which was long divided between many petty kings of the First Men and Andals. About a thousand years ago, Rhoynar refugees fleeing conquest by the Valyrian Freehold in Essos migrated across the Narrow Sea to Dorne, led by their warrior-queen Nymeria. Mors Martell was smitten with Nymeria and chose to join forces with her through marriage-alliance. With their combined strength, they conquered and unified the rest of Dorne. To symbolize their union, the original golden spear sigil of Mors Martell was combined with the red sun sigil of Nymeria, creating the red sun pierced by a golden spear sigil that House Martell has used as a sigil ever since. Like their Rhoynar ancestors, House Martell styled its rulers as "princes" instead of "kings", and kept using the titles, resisting the Targaryen invasion and keeping local laws and traditions even after joining the Seven Kingdoms after a matrimonal alliance. The Martell words are "Unbowed, Unbent, Unbroken" - referring to their history, in which they have never been successfully conquered by outsiders. This makes them unique among all of the Great Houses. During the Targaryen Conquest (three centuries before the War of the Five Kings), Dorne was the only region of the Seven Kingdoms to successfully resist the Targaryens and their dragons. Realizing that large armies could not stand against dragons (as seen at the Field of Fire), nor large castles (as seen at the Burning of Harrenhal), the Dornish instead resorted to guerrilla warfare, ambushing Targaryen soldiers and harassing their supply lines as soon as their dragons moved on to the next castle, then disappearing back into the harsh deserts when the dragons returned. The Dornish armies took advantage of Dorne's arid climate, which helped them to adopt attrition warfare against the invading Targaryens, as the arid climate and harsh wastelands of Dorne cannot easily support large invading armies. Losing many men due to attrition, ultimately even Aegon the Conqueror decided to withdraw from Dorne, to focus on reining in the other six newly conquered kingdoms. House Martell and Dorne have never been successfully conquered. Over a century and a half after the Targaryen Conquest of the rest of Westeros, they were invaded again by King Daeron I Targaryen, the Young Dragon. A military genius, his Conquest of Dorne actually succeeded - on the battlefield. But the initial conquest was followed by a four year long Dornish insurgency, in which occupying troops were again bled through ambush and guerrilla tactics. Lyonel Tyrell, the steward that Daeron I put in charge of Dorne, was then assassinated, and all of Dorne rose up in open rebellion. Daeron I himself was killed attempting to put down the insurrection, and after only four short years House Martell once again ruled an independent Dorne. A few decades later (a little over a century before the War of the Five Kings), King Daeron II the Good managed to finally unite Dorne with the Iron Throne - not through conquest, but by voluntary marriage-alliance on equal terms. Daeron II married the sister of the Prince of Dorne, and the Prince of Dorne married Daeron II's sister. This special, semi-autonomous status allowed Dorne to retain several special privileges, such as the Martells continuing to style themselves as "Prince" or "Princess" instead of "Lord Paramount" and continuing their practice of gender-blind primogeniture. This union did cause several political tensions at the royal court between Daeron II's pro-Martell faction and anti-Martell lords (from the Reach, the Stormlands, and the Dornish Marches), eventually leading to the Blackfyre Rebellion. Generations later, King Aerys II Targaryen (later known as "the Mad King") had no daughters, so he sought a suitable bride for his son Crown Prince Rhaegar Targaryen from outside of the family. Aerys II chose to snub the offer of Tywin Lannister, his own trusted Hand of the King and dutiful servant, that Rhaegar marry his own young daughter Cersei. Instead, a match was arranged with the then-current Princess of Dorne to wed her daughter Elia Martell to Rhaegar.

In Robert's Rebellion, Elia was kept in King's Landing to ensure the continued allegiance of House Martell to the Targaryen's against the rebels. Elia bore Rhaegar two children but all three were later killed during Robert's Rebellion, during the Sack of King's Landing by Tywin Lannister's army. Elia's brothers Doran and Oberyn were outraged and, while peace was restored, the Martells withdrew from interacting with the royal court. During King Robert Baratheon's subsequent reign, the Martells and Dorne were rarely if ever even mentioned at court, except for their Dornish wine.

Practices
"After the tradition of her people, House Martell then ruled Dorne as 'princes', not 'kings' - unless the eldest child was a daughter, for unlike the rest of Westeros, our loyalty isn't commanded by a cock. We follow a Prince or a Princess Martell just the same."

- Oberyn Martell Like their Rhoynar ancestors who migrated to Dorne a thousand years ago, Dornish noble Houses follow gender-blind equal primogeniture, in which the eldest child is the heir regardless of whether that child is male or female. This is different from the male-preference inheritance laws in all of the rest of the Seven Kingdoms, the laws of the First Men and Andals, in which a younger son succeeds ahead of an older daughter. In House Stark, for example, Bran and Rickon are officially ahead of their older sister Sansa in the line of succession, and in House Lannister, Tyrion was officially ahead of Cersei despite being younger than her.

In contrast, a ruler of House Martell is always succeeded by their eldest child, even if it is a daughter. The current ruler of Dorne (when House Martell is fully introduced in Season 5) is Prince Doran Martell, who has been the head of House Martell for many years. The immediately preceding head of House Martell, however, was Doran's mother, who was also the mother of Elia and Oberyn. Doran's mother actually had a younger brother, Lewyn Martell. Under the inheritance laws of the rest of Westeros, Lewyn would have succeeded ahead of Doran's mother, but because Dornish inheritance laws are gender-blind he did not (and therefore he was free to join the elite Kingsguard).

In the style of their Rhoynar ancestors who lived in city-states in Essos (near the location of the later Free Cities), House Martell styles its rulers as "Prince of Dorne" (or "Princess") instead of "King" or "Queen". All members of House Martell are called a Prince/Princess, though the current head of the household is the ruling Prince/Princess. There is little functional difference between the "Prince of Dorne" and a "Lord Paramount of the North", though the title "Prince" is considered to be, at least nominally, more prestigious.

Due to uniting with the Iron Throne through marriage-alliance on equal terms instead of through conquest, the Martells were allowed to retain several special privileges, among which were continuing to style their ruler as a "Prince", and continuing to practice gender-blind equal primogeniture. While many of the Martells are hot-tempered, especially Prince Oberyn, they are a close-knit and loving family, undivided by internal rivalries such as those in House Lannister and House Baratheon.

Season 1
Bran Stark recites the motto of House Martell during a lesson with Maester Luwin.

Season 2
Tyrion Lannister announces his plan to marry Myrcella Baratheon to Prince Trystane Martell of Dorne. The alliance is intended to keep the Dornish from siding with their enemies in the War of the Five Kings, and to ensure the survival of a Baratheon/Lannister heir should King's Landing fall. Cersei is shocked, and tells her brother that the Martells loathe them. Tyrion concurs, but says that this is exactly why they need to seduce the Martells back into allegiance, by offering them a royal marriage alliance.

Some weeks later, Tyrion, Cersei, and Joffrey see Myrcella off from the docks at King's Landing for the first stage of her journey to Dorne.

Season 4
Prince Oberyn Martell, along with a retinue of Dornish lords and knights, arrives in King's Landing to attend the royal wedding in the place of his brother, Prince Doran Martell. Oberyn is joined by his paramour, Ellaria Sand. Oberyn explains the bad blood between the Lannisters and Martells. His sister, Elia Martell, was the wife of Rhaegar Targaryen and she and her children were raped and murdered by Tywin Lannister's troops when they sacked King's Landing. Oberyn holds Tywin personally responsible and is in the capital intent on taking revenge on the Lannisters.

Oberyn and Ellaria represent House Martell at the royal wedding between King Joffrey and Margaery Tyrell, and witness Joffrey's poisoning. Joffrey's uncle Tyrion Lannister is falsely accused of poisoning Joffrey. Lord Tywin subsequently meets with Oberyn in private, and tells him that he wants to ensure that the Martells remain close to the throne, which is still facing numerous threats: the Iron Islands are still in open rebellion to the west, a wildling horde is massing against the Wall to the north, and worst of all, to the east in Slaver's Bay, Daenerys Targaryen possesses three live Dragons and is amassing a large army of her own. As a sign of good faith, Tywin makes Oberyn one of the three judges at Tyrion's trial. Tyrion is subjected to a humiliating show trial at court, which he ends by demanding a Trial by combat. The crown's champion is the fearsome Gregor Clegane, but ultimately Oberyn volunteers to be Tyrion's champion.

Oberyn faces off against the massive Gregor in the following trial by combat in front of the gathered royal court. Oberyn uses speed and agility to outmaneuver and subdue Gregor, but is knocked off his feet during an unguarded moment, after which Gregor crushes Oberyn's skull between his bare hands. Oberyn, however, had coated his spear with manticore venom, one of the deadliest poisons in the Known World, incapacitating and seemingly dooming Ser Gregor.

Season 5
Oberyn's death in King's Landing has caused outrage among the Dornish population, as the prince was popular in Dorne. Among those calling for revenge was Oberyn's lover, Ellaria Sand, and his bastard daughters, the Sand Snakes. They sought to wage war against the Lannisters for killing Oberyn and Elia by using Myrcella Baratheon, Queen Cersei Lannister's daughter who was betrothed to Trystane Martell. However, Prince Doran refused to wage war, believing that it was a war they could not win. He also refused to let Myrcella be harmed and kept her close to him in the Water Gardens, for her safety. However, Doran's attempts to keep the princess safe are ultimately futile as Ellaria secretly poisons Myrcella as she leaves on her return voyage to King's Landing.

Season 6
Prince Doran is escorted back to the Water Gardens by Ellaria and Tyene with whom he reminisces about his late brother and how he was envious of the life he lived. The conversation is ended when Maester Calleote brings word of Myrcella's murder to the Prince. Before he can react, he is promptly assassinated by Ellaria Sand whilst Tyene kills Areo Hotah. As Doran dies in a pool of his own blood, helpless as his guards do nothing but watch, Ellaria angrily states that he is weak for not avenging the deaths of his sister or brother and that weak men will never rule Dorne again. Immediately following this in the harbor at King's Landing, Trystane is killed by Obara and Nymeria who had sneaked aboard the ship. With their deaths, House Martell becomes legally extinct.

Later, Ellaria and the Sand Snakes meet with Olenna Tyrell to persuade her to join the forces of House Tyrell with Dorne, to exact vengeance for the deaths of various members of both House Martell and Tyrell. It is revealed that Ellaria, after hearing of Daenerys Targaryen's recent alliance with Yara and Theon Greyjoy, has aligned Dorne and the forces of the now-extinct House Martell with Daenerys in support of a Targaryen restoration, with the appearance of Varys offering the Targaryen words of "Fire and Blood."

In Daenerys's invasion fleet, some ships can be seen bearing the sun-and-spear sigil of House Martell, although legally extinct, but instead representing Dorne as a whole alongside Tyrell, Greyjoy, and Daenerys's own Targaryen ships. This takes place as Dorne pledges their allegiance to House Targaryen, and sets sail with the other Targaryen allies to exact revenge against House Lannister for the deaths of Elia and Oberyn Martell, and to restore the Targaryen Dynasty to the Iron Throne.

Season 7
Ellaria and the oldest three Sand Snakes arrive at Dragonstone and hold council with Daenerys and her court, where a plan is laid out on how best to deal with Cersei and her allies. The Martells are taken by Yara and the Ironborn fleet to return to Dorne, where they will gather their armies and prepare to lay seige to King's Landing along with the Tyrell armies. En route, however, the Ironborn ships are attacked by Euron Greyjoy and his new fleet. When Euron's lead ship, Silence, crashes into Yara's flagship, Black Wind, his crew boards her ship and begins fighting. Tyene and Ellaria Sand are both captured, while Obara and Nymeria are each killed with their own weapons at Euron's own hands. The sisters are attached to the bowsprit of the ship before Silence departs, leaving Black Wind to burn.

Ellaria and Tyene are paraded through the streets of King's Landing, where they are jeered and pelted with rotten fruits by the smallfolk. The mother and daughter are brought before Queen Cersei Lannister, who thanks Euron for delivering her "justice". Later, Cersei takes Ellaria and Tyene to the dungeons beneath the Red Keep and has them gagged and chained up. As punishment for the murder of her daughter Myrcella Baratheon, Cersei kisses Tyene with the Long farewell and forces Ellaria to watch as her daughter succumbs to the poison. Cersei taunts Ellaria that she will spend the rest of her days in the dungeons watching her daughter's corpse rotting.

Military strength
During the War of the Five Kings, the military of Dorne has been left largely untouched, in part due to their isolation from the conflicts of the war, as Dorne is the southernmost kingdom, with the only known Dornish casualties were taken during Ser Jaime Lannister's mission to Dorne to rescue Princess Myrcella Baratheon, which would end at the Confrontation in the Water Gardens. During the Coup in Dorne, Ellaria Sand, leader of the Sand Snakes states that the Dornish people are with her as she murders Prince Doran Martell, while Dornish Guards watch in support of Ellaria Sand. Prior to Daenerys Targaryen's Invasion of Westeros, Dorne and House Tyrell forged an alliance with Queen Daenerys Targaryen, and join her coalition military. While planning for the upcoming war, the Dornish and Tyrell armies would lay siege to King's Landing, while the Unsullied would lay siege to Casterly Rock. Dorne also possesses a sizable navy, as ships with the sigil of House Martell compose a part of the Allied Targaryen Fleet on route to Westeros. It is likely, however, that most, if not all, of the Dornish Fleet was destroyed along with Queen Yara Greyjoy's faction of the Iron Fleet on route to Dorne to transport the Dornish army to King's Landing. After the naval battle and the death and capture of the Sand Snakes and Ellaria Sand, Dorne was left leaderless, and their army has remained in Dorne, effectively knocked out of the war.

In the books
In the A Song of Ice and Fire novels, House Martell does not play a major role in events until the third and fourth books in the series, only being referenced in the first two.

House Martell was originally a tiny, obscure noble house of Dorne back when the peninsula was home to numerous small, warring states, approximately one thousand years ago. The Rhoynar, refugees from a war against Valyria on the eastern continent, fled to Westeros led by their warrior-queen Nymeria, where they made landfall in Dorne and allied with Lord Mors Martell. After a brief war, Mors named himself the ruler of the unified Kingdom of Dorne, adopting the title "Prince" rather than "King" in Rhoynish fashion. Mors married Nymeria, uniting the bloodlines of the Rhoynar with the native First Men and Andals. As a result, the full name of the family is actually "House Nymeros Martell", with "Nymeros" signifying "of Nymeria". For example, Oberyn's full name is given as "Oberyn Nymeros Martell". However, even the Martells themselves do not usually use the full name, with the inclusion of "Nymeros", except on very formal occasions.

When Aegon I Targaryen invaded Westeros, he conquered six of the seven kingdoms extant at that time, but the Dornish refused to give open battle where Aegon could destroy them with his dragons, instead resorting to hit-and-run attacks which severely damaged his army through attrition. Aegon agreed to leave Dorne to its own devices after trying to conquer it again during the First Dornish War of 4 AC to 13 AC. However, the Dornish once again prevailed and the Martells managed to kill Aegon's wife, Rhaenys, before forcing the Conqueror to agree to peace on their terms. Aegon never tried conquering Dorne again.

A century and a half later, Dorne was briefly occupied by the armies of King Daeron I, but overthrew them in a bloody rebellion. Eventually, roughly a century before the events of the series, Dorne joined the Seven Kingdoms through a peaceful marriage alliance. House Martell's motto, "Unbowed, Unbent, Unbroken", directly references the fact that they were never conquered by outsiders. Because they came under the authority of the Iron Throne through marriage instead of the sword, House Martell and the other Dornish houses continue to practice absolute primogeniture, in which the eldest child is the designated heir, regardless of whether they are male or female. Another major difference is that the rulers of Dorne are styled ruling Princes (or ruling Princesses) instead of Lords Paramount. At the time of the beginning of the narrative the current head of House Martell is the aging Prince Doran. His daughter and eldest child is Arianne Martell: despite being female, she has been actively groomed to succeed her father, as are eldest daughters all over Dorne. In his old age and infirmity (though he retains his wits) Doran has semi-retired, delegating most of the day-to-day governance of Dorne to Arianne.

The Martells were loyal vassals of the Iron Throne, with Princess Elia Martell marrying Prince Rhaegar Targaryen and bearing him two children. During Robert's Rebellion, the Martells were unhappy with Rhaegar's betrayal of Elia by taking Lyanna Stark as his paramour and sparking a war over the matter. Still, they supported King Aerys II Targaryen's bid to retain the throne, predominantly due to Aerys effectively holding Elia as a hostage to ensure their loyalty. The Martells lost many soldiers at the Battle of the Trident and Princess Elia and her children were brutally killed during the Sack of King's Landing by Lannister soldiers. Ironically, the Martells had only grudgingly stayed loyal to the Targaryens during the civil war, but the needless and brutal murder of Elia turned Dorne into a hotbed of pro-Targaryen sentiment (to the point that, after the Sack of King's Landing, Oberyn had wanted to continue the fighting on behalf of Viserys Targaryen). Though House Martell swore fealty to King Robert Baratheon after the war (though this was only due to extensive peace negotiations on the part of Jon Arryn), they have harbored anger and resentment towards the Lannisters ever since and have adopted a mostly isolationist policy ever since, not mixing with the other Great Houses unless totally necessary. As a result, the Dornish have stronger relations with the Free Cities of Essos than the rest of Westeros.

The Martells and Tyrells have been sworn enemies for many generations. Over the centuries, they have fought border wars beyond count, and raided back and forth across mountains and marches even when at peace. The enmity between the two houses waned a bit after Dorne became part of the Seven Kingdoms, but the maiming of Willas Tyrell by the Dornish prince Oberyn Martell in a joust fanned the animosity between the families, though Willas himself does not hold any grudge against Oberyn, as both men knew what happened was simply an unfortunate accident.

In the second novel, Varys reports Tyrion that Prince Doran Martell has called his banners, and there are rumors that he intends to join Renly (Renly tells Catelyn the same thing). Knowing that an alliance between Renly and Dorne will be disastrous to the Lannisters, Tyrion take steps to prevent it by offering Prince Doran to marry Myrcella to Trystane, his sister’s killer, a seat at the Small Council, and some castles on the Marches. Despite Cersei's protests, Tyrion sends Myrcella to Dorne as a token of good faith. The Martells stay neutral throughout the war, although it is unclear whether the reason is Tyrion's offer, or the Martells bide their time.

Tywin, too, understands it is necessary to appease the Martells, lest they form an alliance with Stannis. He is partly correct: as revealed in the fourth and fifth novels, Doran Martell intends to support enemies of House Lannister; the enemies in question, however, are the Targaryens, not the Baratheons.

Cersei deeply hates the Dornish in general and the Martells in particular, thinking that all Dornishmen are snakes, and the Martells are the worst of them. Her hatred is fueled by the fact that Oberyn fought for Tyrion at the trial-by-combat, and had come within a hairbreadth of a victory that would have allowed Tyrion to escape the blame for Joffrey’s murder. This is perhaps the reason for her unsuccessful scheme to assassinate Trystane.

George R.R. Martin has said that the production team isn't certain how many members of House Martell they can fit into the TV series. Doran has three children, while Oberyn and Ellaria have eight daughters. Even for House Tyrell, which has four children in the current generation, two have apparently been cut from the TV series (Loras and Margaery's older brothers from the books). Conversely, in Season 2 the production team thought they might have to cut Stannis Baratheon's only child, Shireen, but subsequently was able to introduce her in Season 3. While Oberyn and Ellaria do appear in Season 4, it remains to be seen how many other Martells can be introduced into the TV continuity in later seasons.

House Martell's name might have been inspired by Charles Martel (Charles the Hammer), who led the Franks to turn back the Muslim invasion of France at the Battle of Tours in 732.
