After the Revolution and War of Independence of 1949/49 failed, politicians and soldiers who were forced to immigration did not give up trying to find ways to the independence of Hungary. The Crimean War, Italian National Movements and wars versus Austria filled Hungarian patriots with hope.

In July 1859 the Piemont Hungarian Legion was founded. The commander-in-chief of the corps dismissed in September was György Klapka. In 1860, Hungarians fighting under the commandment of Garibaldi formed the first Hungarian Legion in Hungary led by István Türr. Later the legion joined the Italian army, but was dismissed in 1867.

Austrian power was shaken again in 1866 due to the powers of Prussia, its allies and the Italian Government. The third ally of Bismarch became Hungary. In 1866 the Legion Klapka was formed. The legion counting 1500 red hat solders lasted 80. The chief of the corps was György Klapka from 26 July to 14 August.

The photos on display show some of the legion members. The pictures were dedicated to the major Ágoston Grisza, commemorating the unsuccessful expedition of the soldiers to Hungary on 3 August 1866.
