On 13 April 1909, while Constantinople was dealing with the consequences of Ottoman countercoup of 1909 an outbreak of violence, known today as the Adana Massacre shook in April the ARF-CUP relations to the core. On 24 April the 31 March Incident and suppression of the Adana violence followed each other. The Ottoman authorities in Adana brought in military forces and ruthlessly stamped out both real opponents, while at the same time massacring thousands of innocent people. In July 1909, the CUP government announced the trials of various local government and military officials, for "being implicated in the Armenian massacres.".
