the founder of modern Czech historiography and a leading figure in the political life of 19th-century Bohemia.

He early came into contact with the resurgence of national feeling that had begun to influence Czech and Slovak intellectuals. His early writings were concerned with aesthetics. In 1823 he settled in Prague, where he was enabled by noble patronage and by an advantageous marriage to devote himself to his scholarly and patriotic interests. In 1827 he became editor of the journal of the Bohemian museum, in which he published articles on aesthetics and on the Czech language (arguing against any far-reaching changes).

In 1832 he began his magnum opus, a history of the Czech nation in Bohemia and Moravia to 1526. Published as Geschichte von Böhmen, 5 vol. (1836–67), and Dějiny národu českého (1848–76), the work lucidly presents Palacký's conception of the nature of Czech history as “the constant contact and conflict between the Slavs on the one hand and Rome and the Germans on the other.” Thus the Hussite period became the central episode of Czech history, epitomizing the national and the religious struggle.

As a politician, Palacký supported the Austro-Slavic conception of a federal Austria, composed of nationalities with equal rights. He was chairman of the Prague Slavic congress in 1848 and attended the constituent assembly that met in Kroměříž (Kremsier) in 1848–49. After the failure of the revolutionary movements Palacký retired from active politics until 1861, when he became a deputy in the Reichsrat.

In his Idea státu rakouského (1865; “Idea of the Austrian State”), Palacký propounded a federalism based not on nationalities but on the historic provinces of the Habsburg empire. His influence on Czech political thought and historiography was immense. The liberal nationalism of Tomáš Masaryk (Masaryk, Tomáš (Garrigue)) and his generation owed much to Palacký.
