This thesis on hand is concerned with the life of Fürst Karl I. von Liechtenstein and a perception about him. But before that the historic context in general and the history of the House of Liechtenstein will be described in detail.Karl I. von Liechtenstein (1569-1627) converted to Catholicism in 1599 and held many high departments in which he had determining influence on the politics of the empire. Karl was raised into the hereditarily “Fürstenstand” in 1608 so he was the former of the royal House of Liechtenstein. During the bohemian riot in 1618 he took up position for King Ferdinand. The victory at the battle of White Mountain (Bílá Hora) in 1620 meant the breakdown of the revolution. Karl was responsible for the detention and the execution of the rebels. In 1621 the trial ended by the execution of 27 condemned men. In 1622 he became viceroy of Bohemia with the authority of state administration. With that authority the state constitution of Bohemia was eliminated. Karl derived a personal benefit from the countless confiscations of rebels goods and ascended to one of the most powerful and richest of all aristocrats of that time.Karl got judged contentious and met with hostility by his contemporaries and, even long after his death, by Czech-national historians. By his contemporaries he was criticised because of his conversion to Catholicism, his official acts as a chairman of the tribunal and governor of Bohemia and also for his involvement in the „Münzkosortium“. In the 19th and 20th century the Czech sense of national identity was characterized by the orientation on the history of the 15th to the 17th century in which the suppression of the bohemian insurgents endued a key part. Czech historiographers emphasize the “Zäsurcharakter” and constitute it as a national tragedy in which Karl arises as a “villain“. Todays historians take up a rather neutral position, they also suggest that the deeds of Karl were oriented by personal interests, religion only played a minor matter, he should not be seen as an opponent of the Czech nation.
