WAfter the Kingdom of Yugoslavia was invaded by the Axis powers during World War II, all of Bosnia was ceded to the newly created Independent State of Croatia. Axis rule in Bosnia led to widespread persecution and mass-killings of native undesirables and anti-fascists. Many Serbs themselves took up arms and joined the Chetniks, a Serb nationalist and royalist resistance movement that conducted ineffective guerrilla warfare against the occupying Nazi forces. On 12 October 1941 a group of 108 notable Muslim citizens of Sarajevo signed the Resolution of Sarajevo Muslims by which they condemned the persecution of Serbs organized by Ustaše, made distinction between Muslims who participated in such persecutions and whole Muslim population, presented information about the persecutions of Muslims by Serbs and requested security for all citizens of the country, regardless of their identity.Bosnia was the geographical mother of the partisan movement, providing ample space amongst its mountains for training and development.
WIn June 1941, Serbs in eastern Herzegovina rebelled against the authorities of the Independent State of Croatia, an Axis puppet state established during World War II on the territory of the defeated and occupied Kingdom of Yugoslavia.

In eastern Herzegovina, the Ustaše perpetrated a series of massacres and attacks against the majority Serb population commencing in the first week of June. Between 3 and 22 June 1941, spontaneous clashes occurred between NDH authorities and groups of Serbs in the region.
