The shorelands of Gondor had been widely colonized by the Númenóreans from around the middle of the Second Age, especially by the Elf-friends loyal to the house of Elendil. When his sons Isildur and Anárion landed in Middle-earth after the drowning of Númenor, they co-founded the Kingdom of Gondor in S. A. 3320. They were welcomed by the colonists already living there, and their claim of lordship was accepted. Elendil, who had founded the Kingdom of Arnor to the north, was held to be the High King of all lands of the Dúnedain. Within the South-kingdom, the hometowns of Isildur and Anárion were Minas Ithil and Minas Anor respectively, and the capital city Osgiliath was situated between them.
