This event was followed by various acts of violence directed against the adherents of the reformed faith, which so exasperated the population that in May, 1525, a rebellion broke out in all parts of the principality. The Archbishop seeing that the situation was taking a serious turn, addressed an urgent appeal for help to Duke William at Munich, which, however, was not answered. Shortly after, thousands of miners and peasants, having won several skirmishes in the country districts, advanced to Salzburg, where they were joined by many of the inhabitants, and promptly set to work to besiege the Archbishop in the fortress, which they continued to do (failing to gain an entrance) until August 15th, when Ludwig of Bavaria arrived with a strong force, and a truce favourable to the peasants was agreed upon. This arrangement, however, was not held to, and in consequence a fierce rebellion broke out again in the following year, but was successfully and cruelly suppressed by forces under the command of the Archduke Ferdinand, supplemented by those of the Suabian League. Although the doctrines of Luther continued to make headway, and religious disturbances still occurred, the latter were not of a serious character; but some half a century later the famous Archbishop Wolf Dietrich von Raitenau, also known for brevity as Wolf Dietrich, on returning from Rome, where he had been to receive the pallium, or ornamental band of white wool worn around the shoulders, which all archbishops at that time had to receive on their appointment before they were empowered to carry out the duties of their office, issued his famous edict on July 9, 1588, for the extermination of the heretics. In consequence of which there was a severe persecution of those who had adopted the Lutheran faith, with great confiscations of their lands and other property. Other acts of this famous Archbishop, including an imposition on salt, the obtaining and making of which formed a very important and remunerative industry, brought about serious friction between him and some of his subjects, and ultimately led on two occasions to his military occupation of the salt district by means of mercenaries. On the first these forces were defeated and driven out by those of Duke William of Bavaria; and on the second the Archbishop's action led to the conquest and occupation of Salzburg by the Duke Maximilian himself, and the ultimate imprisonment and dethroning of Wolf Dietrich on March 7, 1612. He was never released, although efforts were made to obtain freedom and pardon for him, and died in his cell in Hohen-Salzburg five years later. [Sidenote: CATHOLIC PERSECUTIONS]
