Game of Thrones King's Landing

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.
