In early June oversaw the Slavic Congress at Prague as its president. Later that year he was deputed to the Reichstag which sat at town of Kroměříž (Kremsier) between October 1848 and March 1849. He was at this time in favour of a strong Austrian empire, which should consist of a federation of the southern German and the Slavonic states, allowing the retention of their individual rights. This movement was called Austroslavism. Its views met with some degree of consideration at Vienna, and Palacký was even offered a portfolio in the Pillersdorf cabinet. The collapse of the federal idea and the definite triumph of the party of reaction in 1852 led to his retirement from politics.
