John Tausen was born in Denmark 1494. His father was a poor farmer, and John assisted him in his youth. He desired to study, and through hard work he was able to become a monk at the age of 19. He realized the errors of the Roman Catholic church through his study. In 1517 he was sent out to go attend the university of his choice, except Wittenberg where Luther was. Eventually he went to Wittenberg anyway. He was saved there and returned to Denmark in 1521.
Tausen was a gifted preacher, and preached the gospel to the monks and the people around him. At one time he was imprisoned and he preached to the people through the window of his prison cell. King Fredrick appointed him as the preacher in Copenhagen, the capital. There he preached, and many people were converted. He defended the Reformation ably in debates with the Catholics. After the death of Fredrick he was sentenced to death, but the people rioted and he was pardoned. Tausen was the leader of the Reformation in Denmark. He died in 1561.
