King's Landing is the capital of the Seven Kingdoms. It is located on the east coast of Westeros in the Crownlands, overlooking Blackwater Bay. It is the site of the Iron Throne and the Red Keep, the seat of the King of the Andals and the First Men. The walled city is located on uplands just north of where the Blackwater Rush flows into Blackwater Bay. It enjoys a warm climate and life there is luxurious for those that can afford it, although it is not without its slums such as Flea Bottom.
The city is overpopulated and dangerous at the best of times, despite being policed by a City Watch.
King's Landing was founded by King Aegon I Targaryen. He established a small wooden fort atop the hill - which was later named after him - where his ships first landed from Dragonstone, and used this as a base for his campaign to conquer the continent. Having achieved his goal, he established the new capital on the site of his original fort. The city expanded rapidly under his descendants. By the time of Robert's Rebellion, the city had a population of approximately half a million people.
King's Landing has suffered occasional attacks during its existence, most notably during the civil war known as Robert's Rebellion, when Lord Tywin Lannister betrayed King Aerys II Targaryen and ordered his army to brutally sack the city before turning it over to Robert Baratheon as a sign of fealty.
During the War of the Five Kings, the problems in King's Landing have multiplied. The worst of these is the food shortages. Added to this, there has been an influx of refugees into the city seeking the protection of the city walls from the war.
Seat of the King. Named for where Aegon Targaryen "The Conqueror" first landed in Westeros, this city has served as the capital of the Seven Kingdoms ever since. The city is now in the sway of the High Sparrow and the newly-empowered Faith Militant.
