###Input: Martin Luther (/ˈluːθər/ or /ˈluːðər/; German: [ˈmaɐ̯tiːn ˈlʊtɐ] ( listen); 10 November 1483 – 18 February 1546) was a German professor of theology, composer, priest, former monk and a seminal figure in the Protestant Reformation. Luther came to reject several teachings and practices of the Late Medieval Catholic Church. He strongly disputed the claim that freedom from God's punishment for sin could be purchased with money. He proposed an academic discussion of the power and usefulness of indulgences in his Ninety-Five Theses of 1517. His refusal to retract all of his writings at the demand of Pope Leo X in 1520 and the Holy Roman Emperor Charles V at the Diet of Worms in 1521 resulted in his excommunication by the Pope and condemnation as an outlaw by the Emperor.

Luther taught that salvation and subsequently eternal life is not earned by good deeds but is received only as a free gift of God's grace through faith in Jesus Christ as redeemer from sin. His theology challenged the authority and office of the Pope by teaching that the Bible is the only source of divinely revealed knowledge from God and opposed sacerdotalism by considering all baptized Christians to be a holy priesthood. Those who identify with these, and all of Luther's wider teachings, are called Lutherans even though Luther insisted on Christian or Evangelical as the only acceptable names for individuals who professed Christ.

His translation of the Bible into the vernacular (instead of Latin) made it more accessible, which had a tremendous impact on the church and German culture. It fostered the development of a standard version of the German language, added several principles to the art of translation, and influenced the writing of an English translation, the Tyndale Bible. His hymns influenced the development of singing in churches. His marriage to Katharina von Bora set a model for the practice of clerical marriage, allowing Protestant clergy to marry.

Martin Luther was born to Hans Luder (or Ludher, later Luther) and his wife Margarethe (née Lindemann) on 10 November 1483 in Eisleben, Saxony, then part of the Holy Roman Empire. He was baptized as a Catholic the next morning on the feast day of St. Martin of Tours. His family moved to Mansfeld in 1484, where his father was a leaseholder of copper mines and smelters and served as one of four citizen representatives on the local council. The religious scholar Martin Marty describes Luther's mother as a hard-working woman of "trading-class stock and middling means" and notes that Luther's enemies later wrongly described her as a whore and bath attendant. He had several brothers and sisters, and is known to have been close to one of them, Jacob. Hans Luther was ambitious for himself and his family, and he was determined to see Martin, his eldest son, become a lawyer. He sent Martin to Latin schools in Mansfeld, then Magdeburg in 1497, where he attended a school operated by a lay group called the Brethren of the Common Life, and Eisenach in 1498. The three schools focused on the so-called "trivium": grammar, rhetoric, and logic. Luther later compared his education there to purgatory and hell.

In 1501, at the age of 19, he entered the University of Erfurt, which he later described as a beerhouse and whorehouse. He was made to wake at four every morning for what has been described as "a day of rote learning and often wearying spiritual exercises." He received his master's degree in 1505.
