The imperial election of 1619 was an imperial election held to select the emperor of the Holy Roman Empire. It took place in Frankfurt on August 28. Background. This was the sixth imperial election to take place during the Reformation. On October 31, 1517, Martin Luther, a professor of moral theology at the University of Wittenberg, now part of the Martin Luther University of Halle-Wittenberg, had delivered the "Ninety-five Theses" to Albert of Brandenburg, the elector of Mainz. This list of propositions criticized the practice of selling indulgences, remissions of the punishment meted out  for sin in Purgatory. Luther's criticism snowballed into a massive schism in the church, and from there into a split among the states of the empire. By 1600, the elector of the Electoral Palatinate was Calvinist and the electors of Saxony and Brandenburg were Lutheran. Bohemian Revolt. Rudolf II, Holy Roman Emperor, Holy Roman Emperor and king of Hungary and Bohemia, was Catholic. In 1600 he was engaged in the Long Turkish War, which had drained the resources of his kingdoms and of the empire since 1593. On December 28, 1604, following military reverses and an economic crisis in  Hungary, the Hungarian nobleman Stephen Bocskai launched a revolt. The Bocskai uprising lasted until 1606 and put additional pressure on Rudolf's resources. It was in this situation that Rudolf was forced to grant the Letter of Majesty in 1609, allowing the free practice of Protestant religions in Bohemia and creating a Bohemian Protestant state church run by the Protestant estates. In 1617, Matthias, Holy Roman Emperor, by now Holy Roman Emperor and king of Hungary and Bohemia, arranged for the election of Ferdinand II, Holy Roman Emperor as his successor in Bohemia under the terms of the Oñate treaty . The fiercely Catholic Ferdinand II had suppressed Protestantism on his lands in Styria and had repudiated the Letter of Majesty. When, in 1618, Ferdinand II sent his representatives, Vilém Slavata of Chlum and Jaroslav Bořita of Martinice, to Prague to administer the government, they were thrown from the third floor of Prague Castle by members of the dissolved Protestant estates.
