What is "bulgarisation"

Bulgarisation (also known as Bulgarianisation; ) is the spread of Bulgarian culture within various areas in the Balkans.

A number of government policies are considered to be examples of Bulgarisation, including the attempt of the former communist leadership in the 1980s to assimilate a Turkish minority living in Bulgaria and, more recently, allegedly similar efforts towards the Slavic-speaking people inhabiting Pirin Macedonia. This view is disputed because the ethnic Macedonian identity and nationalism emerged in the 20th century outside Pirin Macedonia and actually the local Slavic people in Pirin Macedonia have always been Bulgarians since Middle Ages, with no other than Bulgarian self-identification, and de facto never could have been bulgarisated.
