he emergence of the architectural styles Dutch Classicism and English Palladianism are of particular interest because, in contrast to the art historical epoch of Classicism (1770 1840), they were already developed at the beginning of the 17th century. The aim of this diploma thesis is to work out and justify the various reasons for the shift towards a new architectural style in the United Netherlands and England in the 17th century. This starting point led to the following research question: To what extent did cultural, economic and political backgrounds lead to the emergence f a new architectural style in the United Netherlands and England in the 17th century, and what parallels can be found between Dutch Classicism and English Palladianism, which emerged almost simultaneously? The research question is answered by analysing two buildings, the Mauritshuis in The Hague and the Banqueting House in London. In the course of the scientific work, both buildings and their architectural styles will be thoroughly researched and compared on the basis of an architectural description, in order to be able to show possible parallelities but also disparities between the two architectural styles.
