Independence of Croatia
The independence of Croatia was a process started with the changes in the political system and the constitutional changes in 1990 that transformed the Socialist Republic of Croatia into the modern Republic of Croatia, which in turn proclaimed the first Constitution of Croatia, and held the 1991 Croatian independence referendum.
After the country formally declared independence in June 1991 and the dissolution of its association with Yugoslavia, it introduced a three-month moratorium on the decision when urged to do so by the European Community and the Conference on Security and Cooperation in Europe. During that time the Croatian War of Independence started.
On 8 October 1991, the Croatian Parliament severed all remaining ties with Yugoslavia. The Badinter Arbitration Committee had to rule on the matter. Finally, Croatian independence was internationally recognized in January 1992, when both the European Economic Community and the United Nations granted Croatia diplomatic recognition, and the country was accepted into the United Nations shortly thereafter.
Background
During the World War II period from 1941 to 1945, Croatia was established as a puppet state called the Independent State of Croatia, governed by the ultranationalist, fascist Ustaše, backed by Nazi Germany and Fascist Italy within the territory of the Kingdom of Yugoslavia. From 1945 it became a Socialist federal unit of the Socialist Federal Republic of Yugoslavia, a one-party state run by the League of Communists of Croatia created at the end of World War II in Yugoslavia. Croatia enjoyed a degree of autonomy within the Yugoslav federation. At the turn of the 1970s, a Croatian national protest movement called the Croatian Spring was suppressed by Yugoslav leadership. Still, the 1974 Yugoslav Constitution gave increased autonomy to federal units, essentially fulfilling a goal of the Croatian Spring and providing a legal basis for independence of the federative constituents.In the 1980s, the political situation in Yugoslavia deteriorated, with national tension fanned by the 1986 Serbian SANU Memorandum and the 1989 coups in Vojvodina, Kosovo and Montenegro.
As Slovenia and Croatia began to seek greater autonomy within the federation, including confederate status and even full independence, the nationalist ideas started to grow within the ranks of the still-ruling League of Communists. As Slobodan Milošević rose to power in Serbia, his speeches favored continuation of a unified Yugoslav state—one in which all power would be centralized in Belgrade. In March 1989, the crisis in Yugoslavia deepened after the adoption of amendments to the Serbian constitution that allowed the Serbian republic's government to re-assert effective power over the autonomous provinces of Kosovo and Vojvodina. Up until that time, a number of political decisions were legislated from within these provinces, and they had a vote on the Yugoslav federal presidency level.
In the Gazimestan speech, delivered on June 28, 1989, Milošević remarked on the current "battles and quarrels", saying that even though there were currently no armed battles, the possibility could not be excluded yet. The general political situation grew more tense when in 1989 Vojislav Šešelj publicly consorted with Momčilo Đujić, a World War II Chetnik leader. Years later, Croatian Serb leader Milan Babić testified that Momčilo Đujić had financially supported the Serbs in Croatia in the 1990s. Conversely, Franjo Tuđman made international visits during the late 1980s to garner support from the Croatian diaspora for the Croatian national cause.
Transition to democracy and political crisis
In mid-1989, political parties other than the Communist Party were first allowed, starting a transition from the one-party system. A number of new parties were founded in Croatia, including the Croatian Democratic Union , led by Franjo Tuđman.In January 1990, the Communist Party fragmented along national lines, with the Croatian faction demanding a looser federation. At the 14th Extraordinary Congress of the League of Communists of Yugoslavia, on 20 January 1990, the delegations of the republics could not agree on the main issues in the Yugoslav federation. The Croatian and Slovenian delegations demanded a looser federation, while the Serbian delegation, headed by Milošević, opposed this. As a result, the Slovenian and Croatian delegates left the Congress. Having completed the anti-bureaucratic revolution in Vojvodina, Kosovo, and Montenegro, Serbia secured four out of eight federal presidency votes in 1991, and it was able to heavily influence decision-making at the federal level, because unfavorable decisions could be blocked; this rendered the governing body ineffective. This situation led to objections from other republics and calls for reform of the Yugoslav Federation.
In February 1990, Jovan Rašković founded the Serb Democratic Party in Knin. Its program stated that the "regional division of Croatia is outdated" and that it "does not correspond with the interest of Serb people". The party program endorsed redrawing regional and municipal lines to reflect the ethnic composition of the areas, and asserted the right of territories with a "special ethnic composition" to become autonomous. This echoed Milošević position that internal Yugoslav borders should be redrawn to permit all Serbs to live in a single country. Prominent members of the SDS were Milan Babić and Milan Martić, both of whom later became high-ranking RSK officials. During his later trial, Babić would testify that there was a media campaign directed from Belgrade that portrayed the Serbs in Croatia as being threatened with genocide by the Croat majority and that he fell prey to this propaganda. On 4 March 1990, a meeting of 50,000 Serbs was held at Petrova Gora. People at the rally shouted negative remarks aimed at Tuđman, chanted "This is Serbia", and expressed support for Milošević.
Political moves and civil unrest
In late April and early May 1990, the first multi-party elections were held in Croatia, with Franjo Tuđman's win resulting in further nationalist tensions.A tense atmosphere prevailed in 1990: on 13 May 1990, a football game was held in Zagreb between Zagreb's Dinamo team and Belgrade's Crvena Zvezda team. The game erupted into violence between football fans and police.
On 30 May 1990, the new Croatian Parliament held its first session. President Tuđman announced his manifesto for a new Constitution and a multitude of political, economic, and social changes, including a plan for Yugoslavia as a confederation of sovereign states.
On 25 July 1990, Croatia made constitutional amendments that asserted and effected its sovereignty – the "Socialist" prefix was dropped from the country's name, the President of Croatia replaced the President of the Presidency, in addition to other changes.
The changes in the July 1990 Croatian Constitution did not relate to the status of the Serbs, which remained identical to the one granted by the 1974 Croatian Constitution.
Nationalist Serbs in Croatia boycotted the Sabor and seized control of Serb-inhabited territory, setting up road blocks and voting for those areas to become autonomous. The Serb "autonomous oblasts" would soon become increasingly intent on achieving independence from Croatia.
After HDZ came to power, they conducted a purge of Serbs employed in public administration, especially the police. The Serbs of Croatia held a disproportionate number of official posts: in 1984, 22.6% of the members of the League of Communists of Croatia and 17.7% of appointed officials in Croatia were Serbs, including 28-31% in the Ministry of the Interior. Whereas, in 1981, they represented 11.5% and in 1991, 12.2% of the total population of Croatia. An even greater proportion of those posts had been held by Serbs in Croatia earlier on, which created a perception that the Serbs were guardians of the communist regime.
President Tuđman made several clumsy remarks — such as the one from a 16 April 1990 speech that he was 'glad that his wife is not a Serb' that the Croatian historian has described as something taken out of context. All this was deliberately distorted by Milošević's media in order to artificially spark fear that any form of an independent Croatia is a new "ustashe state": in one instance, TV Belgrade showed Tuđman shaking hands with German Chancellor Helmut Kohl, accusing them of plotting to impose "a Fourth Reich". The new Tuđman government was nationalistic and insensitive towards Serbs, but did not pose a threat to them before the war.
The political crisis escalated when the Serb-populated areas attempted to form an enclave called Serbian Krajina which intended to separate from Croatia if Croatia itself attempted to separate from Yugoslavia. The Serb leadership in Krajina refused to recognize the government of the Republic of Croatia as having sovereignty over them. The crisis began in August 1990 with the Log Revolution as Croatian Serbs cut down trees and used them to block roads. This hampered Croatian tourism and caused alarm in the province of Dalmatia as Croatia was hosting the 1990 European Athletics Championships in Split.
On 21 December 1990, a new "Christmas Constitution" was passed, that adopted a liberal democracy. The constitution defined Croatia as "the national state of the Croatian nation and a state of members of other nations and minorities who are its citizens: Serbs... who are guaranteed equality with citizens of Croatian nationality...." The status of Serbs was changed from an explicitly mentioned nation to a nation listed together with minorities. This constitutional change was also read by the majority of Serb politicians as taking away some of the rights that the Serbs had been granted by the previous Socialist constitution, and it fuelled extremism among the Serbs of Croatia. This was not based on the literal reading of the former Constitution of SR Croatia, which had also treated solely Croats as a constitutive nation, saying Croatia was "national state" for Croats, "state" for Serbs and other minorities.
On 21 February 1991, Croatia declared its Constitution and laws supreme to that of the SFRY, and the Parliament enacted a formal resolution on the process of disassociation from SFR Yugoslavia and possible new association with other sovereign republics.
Over two hundred armed incidents involving the rebel Serbs and Croatian police were reported between August 1990 and April 1991.
