The konfederatka cap of 1863/64 belonged to Edward Pomian-Pożerski (1829-1908), and was worn during the January Uprising. The cap is made of crimson velvet trimmed with sheep-skin.
The January Uprising was directed against the Russian Empire. It broke out on 22 January 1863 in Congress Poland, and on 1st February 1863 in Lithuania. Its extent was limited to the territory of the Russian Partition. After the collapse of the Uprising in autumn 1964, about 38,000 insurgents were sentenced to penal servitude, or deported to Siberia.
