Who were the rulers of Spain when the Muslims where kicked out?

Spain did not exist until 24 years after the Moors were expelled. In 1469 Queen Isabel I of Castile and Leon married King Ferdinand II of Aragon. These 2 monarchs co-ruled the 3 kingdoms after the Moors were expelled in 1492.

The 3 kingdoms were not united to form, what we know as Spain today, until all three were inherited by their grandson, Carlos I.

Carlos I of Spain was also Carlos V, Holy Roman Emperor.
