In 1502, the palace had been built large enough so that the Portuguese Royal Court could begin moving into the palace. In 1508, King Manuel I started expansion works on the palace, which ended in 1510, and appointed Diogo de Arruda as head architect of the project. The King was an absolutist in all manners, and sought to concentrate all his powers in Ribeira Palace, by holding the Portuguese Cortes and installing the Casa da Índia, the imperial administration, in the palace's walls.
