Adam Jerzy Czartoryski

Adam Jerzy Czartoryski (; ; 14 January 177015 July 1861), in English known as Adam George Czartoryski, was a Polish nobleman, statesman, diplomat and author.

The son of a wealthy prince, he began his political career as a foreign minister to the Russian Tsar Alexander I after Poland was partitioned by Russia, Prussia and Austria. He later became a leader of the Polish government in exile and a bitter opponent of Alexander's successor, Tsar Nicholas I. In exile, he advocated for the reestablishment of a sovereign Polish state, which also stimulated early Balkan and Belgian nationalism, and intensified their desire for independence.

Czartoryski was a dedicated patron of arts and greatly contributed to the Czartoryski Collection. In 1798, he purchased one of Poland's most important national treasures – Leonardo da Vinci's ''Lady with an Ermine'', which he brought as a gift for his mother from Italy. Provided by Wikipedia
