What happened in history in Bosnia and Herzegovina

In 1914, a political assassination in Sarajevo set off a chain of events that led to the outbreak of World War I. As more and more young men were sent down into the trenches, influential voices in the United States and Britain began calling for the establishment of a permanent international body to maintain peace in the postwar world.

On 1 March 1942, Tito created the Second Proletarian Brigade.

In liberated territories, the Partisans organised People's Committees to act as civilian government. The Anti-Fascist Council of National Liberation of Yugoslavia (AVNOJ) convened in Bihać on 26–27 November 1942.

On 25 May 1944, he managed to evade the Germans after the Raid on Drvar (Operation Rösselsprung), an airborne assault outside his Drvar headquarters in Bosnia.

On 14 May, he dispatched a telegram to the supreme headquarters Slovene Partisan Army prohibiting the execution of prisoners of war and commanding the transfer of the possible suspects to a military court.

On 17 May Tito suggested that the matter be settled at the meeting of the Cominform to be held that June. However, Tito did not attend the second meeting of the Cominform, fearing that Yugoslavia was to be openly attacked.

On 28 June, the other member countries of the Cominform expelled Yugoslavia, citing "nationalist elements" that had "managed in the course of the past five or six months to reach a dominant position in the leadership" of the CPY.

On 26 June 1950, the National Assembly supported a crucial bill written by Milovan Đilas and Tito regarding "self-management", a type of cooperative independent socialist experiment that introduced profit sharing and workplace democracy in previously state-run enterprises, which then became the direct social ownership of the employees.

On 7 April 1963, the country changed its official name to the Socialist Federal Republic of Yugoslavia.

In the First multi-party election in Bosnia and Herzegovina, in November 1990, votes were cast largely according to ethnicity, leading to the success of the Bosniak Party of Democratic Action, the Serbian Democratic Party and the Croatian Democratic Union.

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".

On 9 January 1992, the Bosnian Serbs proclaimed the "Republic of the Serbian People in Bosnia-Herzegovina" (SR BiH, later Republika Srpska), but did not officially declare independence.

The Bosnian Serb assembly members advised Serbs to boycott the referendums held on 29 February and 1 March 1992. The turnout to the referendums was reported as 63.7%, with 92.7% of voters voting in favour of independence (implying that Bosnian Serbs, which made up approximately 34% of the population, largely boycotted the referendum).

Serbs consider the Sarajevo wedding shooting, when a groom's father was killed on the second day of the Bosnian independence referendum, 1 March 1992, to have been the first victim of the war.

The Serb political leadership used the referendum as a pretext to set up roadblocks in protest. Independence was formally declared by the Bosnian parliament on 3 March 1992.

on 28 March 1992, Izetbegović, after meeting with the then-US ambassador to Yugoslavia Warren Zimmermann in Sarajevo, withdrew his signature and declared his opposition to any type of ethnic division of Bosnia.

The Bijeljina Killings (of mostly Bosniaks) on 1–2 April.

On 3 April, the Battle of Kupres began between the JNA and a combined HV-HVO force that ended in a JNA victory.

On 6 April Serb forces began shelling Sarajevo, and in the next two days crossed the Drina from Serbia proper and besieged Muslim-majority Zvornik, Višegrad and Foča.

"full-scale hostilities had broken out by 6 April", the same day that the United States and European Economic Community (EEC) recognized Bosnia and Herzegovina.

On 23 April, the JNA evacuated its personnel by helicopters from the barracks in Čapljina, which was under blockade since 4 March.

On 27 April, the Bosnian government ordered the JNA to be put under civilian control or expelled, which was followed by a series of conflicts in early May between the two.

Prijedor was taken over by Serbs on 30 April.

On 2 May, the Green Berets and local gang members fought back a disorganized Serb attack aimed at cutting Sarajevo in two.

On May 3, Izetbegović was kidnapped at the Sarajevo airport by JNA officers, and used to gain safe passage of JNA troops from downtown Sarajevo.

On 15 May 1992, a JNA column was ambushed in Tuzla. 92nd Motorised JNA Brigade (stationed in "Husinska buna" barracks in Tuzla) received orders to leave the city of Tuzla and Bosnia-Herzegovina, and to enter Serbia.

The Republic of Bosnia and Herzegovina was admitted as a member State of the United Nations on 22 May 1992.

The Army of Republika Srpska was newly established and put under the command of General Ratko Mladić, in a new phase of the war. Shelling on Sarajevo on 24, 26, 28 and 29 May were attributed to Mladić by UN Secretary-General Boutros Boutros-Ghali.

On 5 and 6 June the last JNA personnel left the city during heavy street fighting and shelling.

On 19 June, a conflict between the units of the TO on one side, and HVO and HOS units on the other side broke out in Novi Travnik.

The 20 June cease-fire, executed in order for UN takeover of the Sarajevo airport for humanitarian flights, was broken as both sides battled for control of the territory between the city and airport.

On 21 June 1992, Bosniak forces entered the Bosnian Serb village of Ratkovići near Srebrenica and murdered 24 Serb civilians.

In June 1992, the Bosnian Serbs started Operation Corridor 92.

The airport crisis led to Boutros-Ghali's ultimatum on 26 June, that the Serbs stop attacks on the city, allow the UN to take control of the airport, and place their heavy weapons under UN supervision.

On 21 July 1992, the Agreement on Friendship and Cooperation was signed by Tuđman and Izetbegović, establishing a military cooperation between the two armies.

On 12 August 1992, the name of the Serbian Republic of Bosnia and Herzegovina was changed to Republika Srpska (RS).

In 1992, the Croat-Bosniak conflict erupted in Bosnia and Herzegovina, just as each was fighting with the Bosnian Serbs. The war was originally fought between the Croatian Defense Council and Croatian volunteer troops on one side and the Army of the Republic of Bosnia and Herzegovina (ARBiH) on the other, but by 1994, the Croatian Army had an estimated 3,000 to 5,000 troops involved in the fighting.

On 7 January 1993, Orthodox Christmas Day, 8th Operational Unit Srebrenica, a unit of the ARBiH under the command of Bratunac Killings, attacked the village of Kravica near Bratunac. 46 Serbs died in the attack: 35 soldiers and 11 civilians.

On 8 January 1993, the Serbs killed the deputy prime minister of the ARBiH Hakija Turajlić after stopping the UN convoy taking him from the airport.

On 16 January 1993, soldiers of the ARBiH attacked the Bosnian Serb village of Skelani, near Srebrenica. 69 people were killed, 185 were wounded. Among the victims were 6 children.

By 26 January, the ARBiH seized control of several villages in the area, including Kaćuni and Bilalovac on the Busovača–Kiseljak road, thus isolating Kiseljak from Busovača. In the Kiseljak area, the ARBiH secured the villages northeast of the town of Kiseljak, but most of the municipality and the town itself remained in HVO control.

On 30 January, ARBiH and HVO leaders met in Vitez, together with representatives from UNPROFOR and other foreign observers, and signed a ceasefire in the area of central Bosnia, which came into effect on the following day.

On 22 February 1993, the United Nations Security Council passed Resolution 808 that decided "that an international tribunal shall be established for the prosecution of persons responsible for serious violations of international humanitarian law".

On 31 March 1993, the United Nations Security Council issued Resolution 816, calling on member states to enforce a no-fly zone over Bosnia-Herzegovina.

On 12 April 1993, NATO commenced Operation Deny Flight to enforce this no-fly zone.

The April incidents escalated into an armed conflict on 15 April in the area of Vitez, Busovača, Kiseljak and Zenica. The outnumbered HVO in the Zenica municipality was quickly defeated, followed by a large exodus of Croat civilians.

On 16 April, the HVO (The Croatian Defence Council) launched a spoiling attack on the village of Ahmići, east of Vitez. After the attacking units breached the ARBiH lines and entered the village, groups of irregular HVO units went from house to house, burning them and killing civilians.

On 16 April, 15 Croat civilians and 7 POWs were killed by the ARBiH in the village of Trusina, north of Jablanica.
