Based on historical evidences, it is believed by Bulgarian, Western and Russian historians that in 1896 or 1897 this first and probably unofficial name was changed to Bulgarian Macedonian-Adrianople Revolutionary Committees (BMARC); and the organisation existed under this name until 1902, when it was changed to Secret Macedonian-Adrianople Revolutionary Organization (SMARO). While part of the Macedonian historians also acknowledge the existence of the name "ВMARC" in the very early period of the Organisation (1894–1896), in the Republic of Macedonia it is generally assumed that in the 1896–1902 period the name of the organization was "SMARO". Both sides lack conclusive documentary evidence, as neither of these names appears in the IMRO documents but is known from undated printed or handwritten statutes. However, Macedonian historians point to the fact that a copy of the "SMARO" statute is kept in London under the year of 1898. It is not disputed that the organization changed its name to Internal Macedonian-Adrianople Revolutionary Organization (IMARO) in 1905 and it is under this name referred to in Bulgarian historiography. After disbanding itself during the first Bulgarian annexation of Macedonia (1915–1918), the organization was revived in 1920 under the name Internal Macedonian Revolutionary Organization (IMRO), under which it is generally known today.
