In January 1990, the Social Council of Citizens, a national body representing all political and ethnic groups, reached a compromise that guaranteed the Turks freedom of religion, choice of names, and unimpeded practice of cultural traditions and use of Turkish within the community. In turn the Bulgarians were promised that Bulgarian would remain the official language and that no movement for autonomy or separatism would be tolerated. Especially in areas where Turks outnumbered Bulgarians, the latter feared progressive "Islamification" or even invasion and annexation by Turkey—a fear that was based on the traditional enmity after the Ottoman rule and had been stirred up after the 1974 invasion of Cyprus. This had been part of the propaganda during by the Zhivkov assimilation campaign and was revived by politicians in post-Communist Bulgaria. Because radical elements of the Turkish population did advocate separatism, however, the non-annexation provision of the compromise was vital.
