Many people have heard of King Ferdinand and Queen Isabella of Spain. However, only a few know all the things they have accomplished. They may be best known for financing the voyages of Christopher Columbus, but they also contributed greatly to the unity of Spain (“Isabella l”). Together, they brought together many kingdoms of the Iberian Peninsula to form what is today Spain. Through the unification of Spain, King Ferdinand and Queen Isabella strengthened Spain into an economic and dominant world power, allowing the spread of Christianity and the colonization of a New World. Before the marriage of Ferdinand and Isabella, the Moors had control of much of the Iberian Peninsula. They desperately wanted to unite Spain and turn it into a Christian nation (“Isabella and Ferdinand”). Isabella carefully devised a plan that would advance her ambition. He proposed to Ferdinand that they get married, which would unify Castile and Aragon and start the unification of Spain ("Ferdinand V"). Isabella then wished to increase her control over Spain by establishing the Spanish Inquisition. His role was to abolish heresy and make Spain a Christian nation (“Spain: History”). The Inquisition officially lasted from 1478 to 1808 (“Queen Isabella's Influence in the New World”). The first problem they tried to deal with during the Inquisition was the Moors. Initially they tried to preach to the people and not to force them to convert to Catholicism. However, plans quickly changed and it was decided that it was more efficient to resort to forced conversion or expulsion against the Moors (Reston). This did not please the Moors. They fought against Ferdinand and Isabella. The fighting between Christians and Moors went on for almost ten......middle of paper......and totally different. The natives could have been more tolerant of the Europeans and could have lived together in unity. This may have changed many things such as religion, culture and other ways of doing things. Isabella and Ferdinand accomplished many things that altered the course of history. They expanded the Spanish empire by financing explorers. They also united several kingdoms to create the country that is Spain today, geographically and economically. However, Ferdinand and Isabella always believed that their greatest achievement was to make Spain a predominantly Christian nation (“Isabella and Ferdinand”). At the end of their reign, King Ferdinand and Queen Isabella colonized a world that had never been discovered, fostered the spread of Christianity, and transformed Spain into a nation with immense economic and industrial power in the world...
