León

León was a kingdom centred on León. By 1337 it belonged to the Castilian Crown, following its union with Castile in 1230.

León remained a constituent kingdom of the Castilian and later Spanish Crown until 1833. In the 19th century it joined Galicia and Asturias in war against Napoleon’s empire and formed its own governing junta. In 1833 the region was divided into León, Zamora and Salamanca provinces.
