[6][7] Byzantine historian George Kedrenos identified Aromanians living in what is now Greece in the 11th century.

[9] In 1902, Romanian politician Alexandru Lahovary advocated for the recognition of the Aromanians as a distinct millet, which was granted in 1905.

[10] The group became more distinct towards the end of the 19th century, with a split occurring between Vlachs who identified more closely with Romania and those who were linked more to Greece.

The Orthodox Patriarch decided that if the Vlachs were to conduct services in their own language, they would be denied their own clerical head.

[12] The Ottoman Ministry of Justice and Religious Denomination determined in 1891 that the Vlach had a right to worship in their own language; in 1892, the Ministry of Justice warned the Greek Patriarch that if Vlach-language services were not instituted, the Vlachs would likely established their own church.
