King of Winter and Ice (asoiaf)

In 4 AC, King Aegon I Targaryen launched an invasion of Dorne, intend on completing his conquest of the Seven Kingdoms. However, although House Wyl led an assault against the Targaryen forces in the Boneway, the other Dornish lords abandoned their castles, neither willing to defend them nor willing to bend the knee.

The first assault was led by Queen Rhaenys Targaryen. On her way to Sunspear, she seized the Dornish seats she encountered and had her dragon Meraxes burn the Planky Town. Meanwhile, King Aegon I and Lord Harlan Tyrell fought in the Prince's Pass, facing heavy resistance as their forces were ambushed by Dornish defenders who fled and hid as soon as the dragons took to the air, and Lord Orys Baratheon led a force through the Boneway. Lord Harlan Tyrell, while leading his army to Hellholt, saw many of his soldiers die of thirst and due to the heat. Those who finally managed to reach Hellholt found the castle to be deserted.

King Aegon briefly besieged Yronwood, which was defended by a few handfuls of old men, boys, and women. He found Skyreach abandoned, but at Ghost Hill was challenged to single combat by Lord Toland's champion. After Aegon had killed the man with Blackfyre, he discovered that the "champion" had in truth been Lord Toland's mad fool. Worse, Ghost Hill turned out to be deserted as well.

Lord Orys Baratheon fared worse in his assault up the Boneway. His army was pelted with rocks, arrows, and spears from above, while his men were murdered in the night. Towards the end, the Dornishmen blocked the Boneway both in front of Orys' army and behind, and the Wyl of Wyl managed to capture Lord Orys and many of his bannermen and knights. They would remain captives of House Wyl until 7 AC.

When the Targaryens finally arrived at Sunspear, they discovered that Princess Meria had vanished. Declaring themselves victorious, King Aegon and Queen Rhaenys placed Dorne under the rule of the Iron Throne. They returned to King's Landing, leaving Lord Jon Rosby as castellan of Sunspear and Warden of the Sands, and charged Lord Harlan Tyrell with putting down any revolts that might arise.

Aegon and Rhaenys had only just returned to King's Landing when the Dornish rebelled against the Targaryens. From Sunspear's shadow city Dornishmen came forth, retaking the castle. Lord Rosby was captured and thrown from a window atop the Spear Tower by Princess Meria Martell. In 5 AC, Lord Harlan Tyrell marched his army from Hellholt, intend on taking Vaith and Sunspear. In the deserts of Dorne the entire army disappeared.

Elsewhere, entire garrisons were put to the sword. The knights who had been in charge of the garrisons were horrifically tortured and mutilated. Lord Wyl, called the Wyl of Wyl and the Widow-lover, eventually agreed to ransom back Lord Orys Baratheon and the other captured lords. In 7 AC, the captives were ransomed back for each man's weight in gold and set free. However, the Wyl of Wyl took off their sword hands, so they could "never take up arms against Dorne again". Orys became bitter and obsessed with revenge and resigned his office as Hand of the King.

Intent on revenge, King Aegon I unleashed his dragons. The castles who remained defiant were burned time and time again, whereupon the Dornishmen retaliated in 8 AC by setting half the rainwood on Cape Wrath ablaze and sacked half a dozen towns and villages.

In 9 AC, the dragons struck again, burning several seats. The next year, Lord Fowler attacked Nightsong, taking its defenders hostage, while Ser Joffrey Dayne marched an army to Oldtown and razed the fields and villages nearby. The Targaryens unleashed their dragons a third time, this time upon Starfall, the seat of House Dayne, Skyreach, the seat of House Fowler, and Hellholt, the seat of House Uller. At Hellholt, the dragon Meraxes was shot down from the sky, with Queen Rhaenys Targaryen upon her back, when a bolt from a scorpion pierced the dragon's eye. Although Meraxes destroyed the castle's highest tower and part of its curtain wall in its fall, the death of both dragon and queen was the greatest success the Dornish had against the Targaryens.

The grief Aegon and Visenya felt at the death of Rhaenys was great; the next two years would later be called the years of the Dragon's Wroth. The Targaryens burned every Dornish stronghold at least once, with the exception of Sunspear and its shadow city. The Dornish believed that the Targaryens refused to attack Sunspear because they were afraid that Princess Meria might have purchased a device from Lys to slay dragons with. Archmaester Timotty offers a different explanation, suggesting in his Conjectures that Aegon hoped this would instead turn the Dornish against the Martells. Indeed, letters have been discovered in which Marcher lords urge Dornish lords to surrender, while claiming that House Martell had purchased their safety from the dragons. Regardless of the truth, the Dornish lords and smallfolk remained loyal.

Aegon and Visenya also placed bounties on the heads of Dornish lords, who, in turn, placed bounties on the Targaryens and their allies. Half a dozen Dornish lords were successfully assassinated, though only two of their killers ever lived to collect their bounties. King Aegon was attacked on three occasions, and Visenya was attacked on several occasions as well. One day, when Aegon and Visenya were assaulted on the streets of King's Landing, only Visenya's swift intervention saved Aegon's life. This attack led to the creation of the elite royal bodyguard known as the Kingsguard in 10 AC. Lord Fell was killed in a brothel in King's Landing, while the Wyl of Wyl committed atrocities, particularly in Fawnton and Old Oak.

Although Dorne was a blasted, burning ruin from the Red Mountains to the mouth of the Greenblood, the Dornish continued to fight. It was not until Lord Dayne and the lords that once proclaimed him their king warned the Martells of Sunspear to either get rid of dragons or surrender, otherwise they will rebel against them and bend the knee to House Targaryen that Nymor Martell, son of Meria Martell, finally after the death of the stubborn Meria Martell decided to sue for peace.

The First Dornish War came to an end in 13 AC, when, following the death of Princess Meria Martell, her elderly son Nymor, now the ruling Prince of Dorne, sent his daughter Deria to King's Landing with an escort as a peace envoy. She brought with her the skull of Rhaenys's dragon Meraxes and a letter from Prince Nymor. The sight of the dragon's skull angered many at the royal court, such as Queen Visenya Targaryen and Lord Orys Baratheon, but Aegon refused to act against the delegation. Instead, Deria was allowed to deliver her father's terms. Prince Nymor wanted peace but still wanted to keep his pride intact. So, he agreed to make Dorne a part of Aegon's rule, but the Martells will keep their title as Prince/Princess of Dorne, they will pay homage to Tragaryens but will not bend the knee, they will not be persecuted for the death of any that died in the war and the crown will not interfere in the matters of Dorne. While Aegon wanted to refuse but tired of this 9-year long war he decided to agree.

And that's how Dorne was brought into the fold, and the 9 yearlong dornish war of conquest came to an end. But despite these, hostilities will continue between Dorne, Stormlands and Reach and many rebels will rear up in Dorne known as the Vulture Kings.

Author's Note

It was seriously only possible in books that lords didn't rebel after their towns, cities and castles were burned and people of kings landing rose up in rebellion against Rhaenyra in Dance of Dragons just out of hunger. But here when their crops and homes were burned, rations were used by armies instead of reaching people, they never rebelled in 9 years.

In real life it's just not possible.
