From December 1984 the Bulgarian government carried out what it called the Revival Process, compelling more than 800,000 ethnic Turks and other Muslims to replace their names with Slavic ones within about three months and restricting Turkish-language and Muslim religious practice. Protests were suppressed by force, including with live rounds at Momchilgrad in December 1984. In the summer of 1989 the authorities opened the border and pressed the minority to leave for Turkey in what was officially styled the 'Great Excursion'; around 320,000 people, about a third of Bulgaria's Turkish population, crossed within months, in the largest single displacement in Cold War Europe. After the fall of Zhivkov in November 1989 and the restoration of names and rights, up to 200,000 returned by the end of 1991. The Bulgarian parliament formally declared the events a form of ethnic cleansing in 2012; charges brought against communist-era leaders in the early 1990s were reduced or dropped and no one was ever convicted.
The Bulgarian communist government under Todor Zhivkov forcibly renamed its Turkish and Muslim minority and then drove roughly a third of it across the border into Turkey
Bulgaria's communist censuses after 1975 recorded no Turkish nationality, so the size of the minority is estimated rather than counted: Western and Turkish estimates for 1989 run from 800,000 to 900,000, and the first post-communist census in 1992 recorded 800,052 people declaring Turkish ethnicity. Bulgarian official statements at the time denied the existence of a Turkish minority altogether.
RFE/RL reports that the crackdown accompanying the forced name changes killed up to 2,500 Turks, an upper-bound figure drawn from community and activist accounts. No state investigation produced an official count, prosecutions were abandoned, and no lower bound is authoritatively established.
RFE/RL and Balkan Insight document the compulsory replacement of Turkish names for over 800,000 people and state restrictions on Turkish ethnic and Muslim religious expression.
