The Turkish minority, once considerably more substantial in size, dates back to the centuries of Turkish rule (see ch. 2). A steady emigration of Turks from Bulgaria to Turkey after World War I and the expulsion of some 150,000 in the 1950-51 period reduced their number. Most of the remaining Turks are tobacco growers or artisans, who live in rural areas in the eastern third of the country and along the Danube River. Their traditional peasant conservatism, bolstered by their Islamic faith, has made them less willing to adapt to the contemporary social order than the rest of the population. A majority would like to emigrate to Turkey, but the Bulgarian government has been unwilling to let them go because the country cannot afford such a population loss. Turkey, for its part, could not absorb the Bulgarian Turks without seriously endangering its own economy and therefore has not encouraged their desires. By agreement between the two governments, about 30,000 close relatives of Turks who left Bulgaria in the 1950-51 period will be allowed to emigrate during the 1970s. The majority of Bulgarian Turks, however, have little hope of leaving in the foreseeable future. In spite of the desire of its members to leave the country, the Turkish minority has posed no serious problem to the Bulgarian government. The government has made an effort to integrate the minority into national life, at the same time preserving its cultural distinctions, which are guaranteed by the constitution. Gypsies are not considered a national minority by the state, although they consider themselves such. Strongly attached to their nomadic way of life, the Gypsies have been reluctant to settle in a permanent place and to integrate themselves into the national society. They continue to follow their traditional occupations as musicians, tinsmiths, and horsemen. The existence of a Macedonian minority has been disputed over many decades by Yugoslavia and Bulgaria. Bulgaria has consistently claimed that Macedonians are ethnically Bulgarians, that their language is a dialect of Bulgarian, and that their land is a part of Bulgaria. Yugoslavia, on the other hand, has given legal recognition to a Macedonian nationality by establishing the People's Republic of Macedonia and by designating the Macedonian language one of the official languages of the federal republic (see ch. 2; ch. 10).
