Several movements whose goals were the establishment of an autonomous Macedonia, which would encompass the entire region of Macedonia, began to arise in the late 19th century; the earliest of these was the Bulgarian Macedonian-Adrianople Revolutionary Committees, later becoming Secret Macedonian-Adrianople Revolutionary Organization (SMARO). In 1905 it was renamed the Internal Macedonian-Adrianople Revolutionary Organization (IMARO), and after World War I the organisation separated into the Internal Macedonian Revolutionary Organization (IMRO) and the Internal Thracian Revolutionary Organisation (ITRO).
