Luther's Theses and the Reformation
Luther presented theses on indulgences, and printing carried the dispute across cities; subsequent reforms changed relations among churches, states, and education in Europe.

The story
In 1517, the Wittenberg scholar Martin Luther presented the Ninety-Five Theses, questioning practices associated with indulgences. The theses originally belonged to university theological debate, but were quickly reprinted and entered wider public discussion. Luther subsequently broke with the papacy, while other reformers proposed different doctrines and institutional arrangements; princes and cities combined religious choices with political interests. Reform encouraged changes in Bible translation, schools, and church organization, but also led to persecution and war. The traditional story of posting the theses on a church door is disputed in the historical evidence, and the Reformation likewise cannot be reduced to an action completed by one person in a single day.
Elsewhere in the world
Printing broadened the reach of doctrinal debates, while European overseas expansion brought Catholic missionary activity and colonial politics to the Americas and Asia.
