Besides its demographic and communal diversity (the Yugoslav census of 1931 distinguished Serbo-Croats, Slovenes, Germans, Magyars, Romanians, Vlachs, Albanians, Turks, ‘Other Slavs’, Jews, Gypsies and Italians), Yugoslavia also displayed wide disparities of custom, wealth and economic development. In parts of it, the Middle Ages had barely faded away by 1950, while others were modern, urbanized and contained significant industry. Overall, what were mainly agricultural economies had been impoverished by fast-growing populations. Yet Yugoslav politics between the two wars had turned out to be in the main about a Croat–Serb antagonism and this was deepened by wartime atrocity and struggle in a three-sided civil war between Croatians, the mainly Serb Communists (themselves led by the Croatian, Tito) and Serb royalists after 1941. This struggle began with a campaign of terror and ethnic cleansing launched against the 2 million Serbs of the new Croatia (which included Bosnia and Herzegovina). It ended in Communist victory in 1945, and the effective containment of the different nationalities by Tito’s dictatorship within a federal structure; this seemed to solve the old Bosnian and Macedonian problems and was likely to be able to ward off the territorial ambitions of outsiders. Forty-five years later, and ten years after Tito’s death, however, the old issues suddenly revealed themselves to be still vigorously alive.
In 1990 the Yugoslav federal government’s attempts to deal with its economic troubles were accompanied by accelerating political fragmentation. Democratic self-determination finally undid the Tito achievement as Yugoslavs of different nationalities began to cast about to find ways of filling the political vacuum left by the collapse of Communism. Parties formed representing Serb, Croat, Macedonian and Slovene interests as well as one in favour of the Yugoslav idea and the federation itself. Soon, all the republican governments, except that of Macedonia, rested on elected majorities, and new national minority parties had even begun to make themselves heard inside the individual republics. Croatian Serbs declared their own autonomy and there was bloodshed in the Serbian province of Kosovo, four-fifths of whose inhabitants were Albanian. The proclamation of an independent republic there had been a major symbolic affront to the Serbians – as well as of concern to the Greek and Bulgarian governments, whose predecessors had not ceased to cherish Macedonian ambitions since the days of the Balkan wars. In August, sporadic fighting by air and ground forces had begun between Serbs and Croats. Precedents for intervention by outsiders did not ever seem promising – though different views were held by different EC countries – and prospects for it became even less attractive when the USSR in July uttered a warning about the dangers of spreading local conflict to the international level. By the end of the year Macedonia, Bosnia-Herzegovina and Slovenia had all, like Croatia, declared themselves independent.
The Soviet warning was the last diplomatic
