Wenceslas IV. Charles was succeeded by his son Wenceslas, who was then seventeen years of age. His reign marks the decline of the rule of the house of Luxemburg over Bohemia. He was a weak and incapable sovereign, but the very exaggerated accusations against him, which are found principally in the works of older historians, are mainly due to the fact that the king and to a larger extent his queen, Sophia, for a time furthered the cause of church reform, thus incurring the displeasure of Romanist writers. During the earlier part of the reign of Wenceslas a continual struggle took place between the king and the powerful Bohemian nobles, who indeed twice imprisoned their sovereign. Wenceslas also became involved in a dispute with the archbishop, which resulted in the death of the famous John of Nepomuk. Huss and the Hussites The later part of the reign of Wenceslas is a record of incipient religious conflict. The hold of the Church of Rome on Bohemia had already been weakened during the reign of King Charles by attacks on the immorality of the clergy, which proceeded from pious priests such as Milic and Waldhauser. The church schism, during which the rival pontiffs assailed each other with all the wild threats and objurgations of medieval theological strife, necessarily alienated the Bohemians to a yet greater extent. Almost the whole Bohemian nation therefore espoused the cause of Huss (q.v.). Wenceslas on the occasion of these disputes displayed the weakness and irresolution that always characterized him, but Queen Sophia openly favoured the cause of Huss, who for some time was her confessor. Huss was tried before the council of Constance (q.v.), to which he had proceeded with a letter of safe conduct given by Wenceslas's brother Sigismund, king of the Romans. He was declared a heretic and burnt on the 6th of July 1415. The inevitable and immediate result of this event was the outbreak of civil war in Bohemia, where Huss was greatly revered by the large majority of the population. The nobles of Bohemia and Moravia met at Prague on the 2nd of September 1415, and sent to the council the famed _Protestatio Bohemorum_, in which they strongly protested against the execution of Huss, "a good, just and catholic man who had for many years been favourably known in the Kingdom by his life, conduct and fame, and who had been convicted of no offence." They further declared that all who affirmed that heresy existed in Bohemia were "liars, vile traitors and calumniators of Bohemia and Moravia, the worst of all heretics, full of all evil, sons of the devil." They finally stated "that they would defend the law of our Lord Jesus Christ and its pious, humble and steadfast preachers at the cost of their blood, scorning all fear and all human decrees that might be contrary to them."[2] This protest was a declaration of war against the Roman church, and marks the beginning of the Hussite wars.
