European artists in a generally academic style who were well known as painters of battle scenes, still often of subjects from the Napoleonic Wars or older conflicts, included Albrecht Adam, Nicaise de Keyser, Piotr Michałowski Antoine Charles Horace Vernet, Emile Jean Horace Vernet, Wilhelm Camphausen and Emil Hünten. The rise of nationalism promoted battle painting in countries such as Hungary (great attention paid to uniforms), Poland (huge forces) and the Czech Lands. Jan Matejko's enormous "Battle of Grunwald" (1878) reflects Pan-Slav sentiment, showing various Slav forces joining together to smash the power of the Teutonic Knights.
