In March 1918, ethnic and religious tension grew and the Armenian-Azeri conflict in Baku began. The Musavat and Ittihad parties were accused of Pan-Turkism by the Bolsheviks and their allies. The Armenian and Muslim militias engaged in an armed confrontation, with the formally neutral Bolsheviks tacitly supporting the Armenian side. All the non-Azeri political groups of the city joined the Bolsheviks against the Muslims: Bolsheviks, Dashnaks, Social Revolutionaries, Mensheviks, and even the anti-Bolshevik Kadets found themselves for the first time on the same side of the barricade because they were all fighting "for the Russian cause". Equating the Azeris with the Ottoman Turks, the Dashnaks launched a massacre on the city's Azeris in revenge for the Armenian genocide in the Ottoman Empire. As a result, between 3,000 and 12,000 Muslims were killed in what is known as the March Days. Muslims were expelled from Baku or went underground. At the same time, the Baku Commune was involved in heavy fighting with the advancing Ottoman Caucasian Army of Islam in and around Ganja. Major battles occurred in Yevlakh and Agdash, where the Turks routed and defeated Dashnak and Russian forces.
