Thomas Müntzer ( – 27 May 1525) was a German preacher and theologian of the early Reformation whose opposition to both Martin Luther and the Roman Catholic Church led to his open defiance of late-feudal authority in central Germany. Müntzer was foremost amongst those reformers who took issue with Luther's compromises with feudal authority. He became a leader of the German peasant and plebeian uprising of 1525 commonly known as the German Peasants' War. He was captured after the Battle of Frankenhausen, tortured and executed.
