Order of Calatrava
The Order of Calatrava (, ) was one of the four Spanish military orders and the first military order founded in Castile, but the second to receive papal approval. The papal bull confirming the Order of Calatrava was given by Pope Alexander III on September 26, 1164. Most of the political and military power of the order dissipated by the end of the 15th century, but the last dissolution of the order's property did not occur until 1838.
