Internal Macedonian Revolutionary Organization - Interwar Period

Interwar Period

The post-war Treaty of Neuilly again denied Bulgaria what it felt was its share of Macedonia and Thrace. After this moment the combined Macedonian-Adrianopolitan revolutionary movement separated into two detached organizations: Internal Thracian Revolutionary Organisation (bulg. Вътрешна тракийска революционна организация) and Internal Macedonian Revolutionary Organisation. ITRO was a revolutionary organisation active in the Greek regions of Thrace and Macedonia to the river Strymon and Rhodope Mountains between 1922 and 1934. The reason for the establishment of ITRO was the transfer of the region from Bulgaria to Greece in May 1920. ITRO proclaimed its goal as the "unification of all the disgruntled elements in Thrace regardless of their nationality", and to win full political independence for the region. Later IMRO created as a satellite organisation the Internal Western Outland Revolutionary Organisation (bulg. Вътрешна западнопокрайненска революционна организация), which operated in the areas of Tsaribrod and Bosilegrad, ceded to Yugoslavia. IMRO began sending armed bands called cheti into Greek and Yugoslav Macedonia and Thrace to assassinate officials and stir up the spirit of the oppressed population. Оn 23 March 1923 Aleksandar Stamboliyski, who favoured a détente with Greece and Yugoslavia, so that Bulgaria could concentrate on its internal problems, signed the Treaty of Niš with the Kingdom of Serbs, Croats and Slovenes and undertook the obligation to suppress the operations of the IMRO carried out from Bulgarian territory. However, in the some year IMRO agents assassinated him. IMRO had de facto full control of Pirin Macedonia (the Petrich District of the time) and acted as a "state within a state", which it used as a base for hit and run attacks against Yugoslavia with the unofficial support of the right-wing Bulgarian government and later Fascist Italy. Because of this, contemporary observers described the Yugoslav-Bulgarian frontier as the most fortified in Europe.

In 1923 and 1924 during the apogee of interwar military activity according to IMRO statistics in the region of Yugoslav (Vardar) Macedonia operated 53 chetas (armed bands), 36 of which penetrated from Bulgaria, 12 were local and 5 entered from Albania. The aggregate membership of the bands was 3245 komitas (guerilla rebels) led by 79 voivodas (commanders), 54 subcommanders, 41 secretaries and 193 couriers. 119 fights and 73 terroristic acts were documented. Serbian casualties were 304 army and gendarmery officers, soldiers and paramilitary fighters, more than 1300 were wounded. IMRO lost 68 voivodas and komitas, hundreds were wounded. In the region of Greek (Aegean) Macedonia 24 chetas and 10 local reconnaissance detachments were active. The aggregate membership of the bands was 380 komitas led by 18 voivodas, 22 subcommanders, 11 secretaries and 25 couriers. 42 battles and 27 terrorist acts were performed. Greek casualties were 83 army officers, soldiers and paramilitary fighters, over 230 were wounded. IMRO lost 22 voivodas and komitas, 48 were wounded. Thousands of locals were repressed by the Yugoslav and Greek authorities on suspicions of contacts with the revolutionary movement. The population in Pirin Macedonia was organized in a mass people's home guard. This militia was the only force, which resisted the Greek army when the Greek dictator, General Pangalos launched a military campaign against Petrich District in 1925. In 1934 the Bulgarian army confiscated 10,938 rifles, 637 pistols, 47 machine-guns, 7 mortars and 701,388 cartridges only in the Petrich and Kyustendil Districts. At the same time an youth's extension of IMRO, the Macedonian Youth Secret Revolutionary Organization was created. The statute of MYSRO was approved personally from IMRO's leader Todor Alexandrov. The aim of MYSRO was in concordance with the statute of IMRO – unification of all of Macedonia in an authonomous unit, within a future Balkan Federative Republic.

The Sixth Congress of the Balkan Communist Federation under the leadership of the Bulgarian communist Vasil Kolarov and the Fifth Congress of the Comintern, an adjunct of the Soviet foreign policy, held concurrently in Moscow in 1923, voted for the formation of an “Autonomous and Independent Macedonia and Thrace.” In 1924 IMRO entered negotiations with the Macedonian Federative Organization and the Comintern about collaboration between the communists and the Macedonian movement and the creation of a united Macedonian movement. The idea for a new unified organization was supported by the Soviet Union, which saw a chance for using this well developed revolutionary movement to spread revolution in the Balkans and destabilize the Balkan monarchies. Alexandrov defended IMRO's independence and refused to concede on practically all points requested by the Communists. No agreement was reached besides a paper "Manifesto" (the so-called May Manifesto of 6 May 1924), in which the objectives of the unified Macedonian liberation movement were presented: independence and unification of partitioned Macedonia, fighting all the neighbouring Balkan monarchies, forming a Balkan Communist Federation and cooperation with the Soviet Union. Failing to secure Alexandrov's cooperation, the Comintern decided to discredit him and published the contents of the Manifesto on 28 July 1924 in the "Balkan Federation" newspaper. VMRO's leaders Todor Aleksandrov and Aleksandar Protogerov promptly denied through the Bulgarian press that they've ever signed any agreements, claiming that the May Manifesto was a communist forgery.

Shortly after, Todor Alexandrov was assassinated in unclear circumstances and IMRO came under the leadership of Ivan Mihailov, who became a powerful figure in Bulgarian politics. While IMRO's leadership was quick to ascribe Alexandrov's murder to the communists and even quicker to organise a revenge action against the immediate perpetrators, there is some doubt that Mihailov himself might have been responsible for the murder. Some Bulgarian and Macedonian historians like Zoran Todorovski speculate that it might have been the circle around Mihailov who organised the assassination on inspiration by the Bulgarian government, which was afraid of united IMRO-Communist action against it. However, neither version is corroborated by conclusive historical evidence. The result of the murder was further strife within the organisation and several high-profile murders, including that of Petar Chaulev (who led the Ohrid-Debar Uprising against the Serbian occupation) in Milan and ultimately Protogetov himself.

In this interwar period IMRO led by Aleksandrov and later by Mihailov took actions against the former left-wing assassinating several former members of IMORO's Sandanist wing, who meanwhile had gravitated towards the Bulgarian Communist Party and Macedonian Federative Organization. Gjorche Petrov was killed in Sofia in 1922, Todor Panitsa (who previously killed the right-wing oriented Boris Sarafov and Ivan Garvanov) was assassinated in Vienna in 1924 by Mihailov's future wife Mencha Karnichiu. Dimo Hadjidimov, Georgi Skrizhovski, Alexander Bujnov, Chudomir Kantardjiev and many others were killed in the events on 1925. Meanwhile, the left-wing later did form the new organisation based on the principles previously presented in the May Manifesto. The new organization which was an opponent to Mihailov's IMRO was called IMRO (United) was founded in 1925 in Vienna. However, it did not have real popular support and remained based abroad with no revolutionary activities in Macedonia. Mihailov's group of young IMRO cadres soon got into conflict with the older guard of the organization. The latter were in favour of the old tactic of incursions by armed bands, whereas the former favoured more flexible tactics with smaller terrorist groups carrying selective assassinations. The conflict grew into a leadership struggle and Mihailov soon in turn ordered the assassination in 1928 of a rival leader, General Aleksandar Protogerov, which sparked a fratricidal war between "Mihailovists" and "Protogerovists". The less numerous Protogerovists soon became allied with Yugoslavia and certain Bulgarian military circles with fascist leanings and who favoured rapprochement with Yugoslavia. The policy of assassionations was effective in making Serbian rule in Vardar Macedonia feel insecure but in turn provoked brutal reprisals on the local peasant population. Having lost a lot of popular support in Vardar Macedonia due to his policies, Mihailov favoured the "internationalization" of the Macedonian question.

He established close links with the Croatian Ustashi and Italy. Numerous assassinations were carried out by IMRO agents in many countries, the majority in Yugoslavia. The most spectacular of these was the assassination of King Alexander I of Yugoslavia and the French Foreign Minister Louis Barthou in Marseille in 1934 in collaboration with the Croatian Ustashi. The killing was carried out by the VMRO assassin Vlado Chernozemski and happened after the suppression of IMRO following the 19 May 1934 military coup in Bulgaria. IMRO's constant fratricidal killings and assassinations abroad provoked some within Bulgarian military after the coup of 19 May 1934 to take control and break the power of the organization, which had come to be seen as a gangster organization inside Bulgaria and a band of assassins outside it. In 1934 Mihailov was forced to escape to Turkey. He ordered to his supporters not to resist to the Bulgarian army and to accept the disarmament peacefully, thus avoiding fratricides, destabilization of Bulgaria, civil war or external invasion. Many inhabitants of Pirin Macedonia met this disbandment with satisfaction because it was perceived as relief from an unlawful and quite often brutal parallel authority. IMRO kept its organization alive in exile in various countries, but ceased to be an active force in Macedonian politics except for brief moments during World War II. Meanwhile a resolution of the Comintern for recognition of a distinct ethnic Macedonian ethnicity, which was accepted also by the Internal Macedonian Revolutionary Organization (United), was published in January, 1934. IMRO (United) remained active until 1936, when it was absorbed into the Balkan Communist Federation.
