The organization was established in Sofia, Bulgaria, in 1891 as a type of cultural and educational society by Macedonian emigrants.
[6] In 1892, it created and published a monthly magazine called Loza (The Vine), which is where their name "Lozari" (Lozars) was derived from.

The Greek national activist from Aromanian background Konstantinos Bellios was considered a "Macedonian compatriot" by the Lozars.
