In 1991 the MRF broadened its platform to embrace all issues of civil rights in Bulgaria, aiming "to contribute to the unity of the Bulgarian people and to the full and unequivocal compliance with the rights and freedoms of mankind and of all ethnic, religious, and cultural communities in Bulgaria." The MRF took this step partly to avoid the constitutional prohibition of political parties based on ethnic or religious groups. The group's specific goals were ensuring that the new constitution protect ethnic minorities adequately; introducing Turkish as an optional school subject; and bringing to trial the leaders of the assimilation campaign in the 1980s. To calm Bulgarian concerns, the MRF categorically renounced Islamic fundamentalism, terrorism, and ambitions for autonomy within Bulgaria.
