When Martin Luther posts his 95 Theses to the door of a church in Germany, this will spark the beginning of the Reformation Movement. The Roman Catholic Church will split because of this. The Theses would attack the church and their practice of selling indulgences, stating that is is currupt to do so. The Protostant
religion quickly formed based off of Martin Luthers ideas about
how the church should be run.
