In 1510, a young monk from Germany named Martin Luther walked 700 miles to Rome on a pilgrimage. He returned home disillusioned, and in 1517, raised 95 difficult theological questions at the university where he taught - and kicked off what became the Protestant Reformation. By questioning corrupt Catholic Church practices, Luther unleashed a torrent of public frustration and undercut the power of the Church. In RICK STEVES SPECIAL: LUTHER AND THE REFORMATION, travel expert Rick Steves sheds light on the 500th anniversary of the Reformation by visiting key sites (including Erfurt, Wittenberg and Rome), and explores the complicated political world of 16th-century Europe, from indulgences to iconoclasts, and from the printing press to the Counter-Reformation. It's a story of power, rebellion and faith that precipitated change in Europe and Christianity forever, and contributed to the birth of our modern world.
