What happened 1991 AD in Bosnia and Herzegovina

On 15 May, Stjepan Mesić, a Croat, was scheduled to be the chairman of the rotating presidency of Yugoslavia. Serbia, aided by Kosovo, Montenegro, and Vojvodina, whose presidency votes were at that time under Serbian control, blocked the appointment, which was otherwise seen as largely ceremonial.

On 19 September 1991, the JNA moved extra troops to the area around the city of Mostar, which was publicly protested by the local government.

On 15 October 1991, the parliament of the Socialist Republic of Bosnia and Herzegovina in Sarajevo passed a "Memorandum on the Sovereignty of Bosnia-Herzegovina" by a simple majority.

On 18 November 1991, the Croatian Community of Herzeg-Bosnia was established in Mostar. Mate Boban was chosen as its president. Its founding document said: "The Community will respect the democratically elected government of the Republic of Bosnia and Herzegovina for as long as exists the state independence of Bosnia and Herzegovina in relation to the former, or any other, Yugoslavia".
