Wojciech Kossak (Paris, France, December 31, 1857 – July 29, 1942, Kraków, Poland) was a Polish painter and member of the celebrated Kossak family of painters and writers. Wojciech Kossak's work was very different in subject matter and style from Jan Matejko's; Kossak belonged to a later generation of artists. Like Matejko, however, he is known for paintings depicting the history of Polish arms and notable battles of Central and Eastern Europe. One of his works depicts the oath taken by Polish national hero, Tadeusz Kościuszko, in the Kościuszko Uprising against Imperial Russia in 1794.
