1.) Discuss the three key developments in the process of political centralization in Spain
All 3 key developments in the process of political centralization in Spain are the union of Aragon and Castile, the taking of Granada, and the Spanish Inquisition.
There were 2 major Spanish kingdoms that merged when Ferdinand of Aragon married Isabella of Castile in 1469. Together, they were known as the Catholic Monarchs.
Granada was the last Muslim stronghold in Spain and was taken under Ferdinand and Isabella. The spanish still ruled over Granada, but made a peace treaty with the muslims. They were allowed to govern themselves and keep their religion while respecting the catholic religion, keeping everyone unified.
The Spanish Inquisition was basically about the Jews and Muslims who claimed to have convert, but were under suspicion of not being true to their word and practicing their former religion in secret. A rule was made to expel those who haven’t truly converted out of Spain and to never return.
