The Reformation and the Thirty Years' War.

Prague played a significant role in the Reformation. The sermons of Jan Hus, a scholar at the university, begun in 1402 at the now-restored Bethlehem Chapel and carrying forward the criticisms of the church developed by the English reformer John Wycliffe, endeared him to the common people but brought him into conflict with Rome; he was burned at the stake in the town of Constance (Konstanz, Ger.) in 1415. Popular uprisings in 1419, led by the Prague priest Jan Zelivsky, included the throwing of city councillors from the windows of the New Town Hall in the incident known as the first Defenestration of Prague. The next year Hussite peasant rebels, led by the great military leader Jan Zizka, joined forces with the Hussites of Prague to win a decisive victory over the Roman Catholic king (later emperor) Sigismund at nearby Vitkov Hill. During the next 200 years, the wealthy merchants became ascendant once more, and the late Gothic architectural style flourished in many churches and buildings, reaching a peak in the fine Vladislav Hall of Hradcany. In 1526, however, the Roman Catholic Habsburgs became rulers of Bohemia and attempted to crush Czech Protestantism. The second Defenestration of Prague (1618), when the governors of Bohemia were thrown from the windows of the council room in Hradcany--one of the major events precipitating the Thirty Years' War--was followed by the decisive defeat of Protestant forces at the Battle of the White Mountain, near the city, in 1620. Twenty-seven Prague commoners and Czech noblemen were executed on the Staromestske Square in 1621; the city ceased to be the capital of the empire, was occupied by Saxons (1631) and Swedes (1648), and went into a decline hastened by two outbreaks of plague. >>
