What did they do with the money of indulgences?

Answer:
Prior to the Protestant Reformation indulgences were sold to relieve individuals of their sins by officials of the Catholic Church such as Johann Tetzel. The money earned from selling indulgences was used to build and restore churches and deepen the pockets of church officials in a period of economic hardship for the Catholic Church. Certain individuals, such as Martin Luther, felt the selling of indulgences contradicted Catholic teaching and spiritual belief.
