the Peace of Saint-Germain-en-Laye in 1570, persecution continued, most notably in the Massacre of Saint Bartholomew's Day on 24 August 1572, in which thousands of Protestants throughout France were killed. A few years before, at the "Michelade" of Nîmes in 1567, Protestants had massacred the local Catholic clergy. Early steps and attempts in the way of tolerance The Norman Kingdom of Sicily under Roger II was characterized by its multi-ethnic nature and religious tolerance. Normans, Jews, Muslim Arabs, Byzantine Greeks, Lombards, and native Sicilians lived in harmony. Rather than exterminate the Muslims of Sicily, Roger II's grandson Emperor Frederick II of Hohenstaufen (1215–1250) allowed them to settle on the mainland and build mosques. Not least, he enlisted them in his Christian army and even into his personal bodyguards. Kingdom of Bohemia (present-day Czech Republic) enjoyed religious freedom between 1436 and 1620 as a result of the Bohemian Reformation, and became one of the most liberal countries of the Christian world during that period of time. The so-called Basel Compacts of 1436 declared the freedom of religion and peace between Catholics and Utraquists. In 1609 Emperor Rudolf II granted Bohemia greater religious liberty with his Letter of Majesty. The privileged position of the Catholic Church in the Czech kingdom was firmly established after the Battle of White Mountain in 1620. Gradually freedom of religion in Bohemian lands came to an end and Protestants fled or were expelled from the country. A devout Catholic, Emperor Ferdinand II forcibly converted Austrian and Bohemian Protestants. In the meantime, in Germany Philip Melanchthon drafted the Augsburg Confession as a common confession for the Lutherans and the free territories. It was presented to Charles V in 1530. In the Holy Roman Empire, Charles V agreed to tolerate Lutheranism in 1555 at the Peace of Augsburg. Each state was to take the religion of its prince, but within those states, there was not necessarily religious tolerance. Citizens of other faiths could relocate to a more hospitable environment. In France, from the 1550s, many attempts to reconcile Catholics and Protestants and to establish tolerance failed because the State was too weak to enforce them. It took the victory of prince Henry IV of France, who had converted into Protestantism, and his accession to the throne, to impose religious tolerance formalized in the Edict of Nantes in 1598. It would remain in force for over 80 years until its
