June 1941 uprising in eastern Herzegovina

In June 1941, Serbs in eastern Herzegovina rebelled against the authorities of the Independent State of Croatia (Croatian: Nezavisna Država Hrvatska, NDH), an Axis puppet state established during World War II on the territory of the defeated and occupied Kingdom of Yugoslavia. As the NDH imposed its authority, members of the fascist Ustaše ruling party began a genocidal campaign against Serbs throughout the country.
