Martin Luther (November 10, 1483 - February 18, 1546) was a Christian theologian and Augustinian monk whose teachings inspired the Protestant Reformation and deeply influenced the doctrines of Protestant and other Christian traditions. Martin Luther was born to Hans and Margaretha Luder on 10 November 1483 in Eisleben, Germany and was baptised the next day on the feast of St. Martin of Tours, after whom he was named. Luther’s call to the Church to return to the teachings of the Bible resulted in the formation of new traditions within Christianity and the Counter-Reformation in the Roman Catholic Church, culminating at the Council of Trent.

His translation of the Bible also helped to develop a standard version of the German language and added several principles to the art of translation. Luther's hymns sparked the development of congregational singing in Christianity. His marriage, on June 13, 1525, to Katharina von Bora, a former nun, began the tradition of clerical marriage within several Christian traditions.
