the Ottomans made another attempt to arrest him but failed again. In the spring of 1910 he and his cheta traversed the Skopje region and organized the revolutionary activities. In early 1911, Aleksandrov became a member of the Central Committee of the IMARO. In 1912, he became a vojvoda in the Kilkis and Thessaloniki districts where he carried out a number of sabotages against Ottoman targets, facilitating this way the Bulgarian cause in the First Balkan War. He supported the Bulgarian Army. In 1913, he was at the headquarters of the Third brigade of the Macedonian Militia in the Bulgarian army. After 1913 he organized the IMARO resistance against other nationalities, such as Serbs and Greeks. With the inclusion of Bulgaria in the First World War in October 1915, Todor Alexandrov was mobilized. At that time, the structures of the Military Defense Forces completely merged into the structure of the Bulgarian army. Aleksandrov himself made considerable efforts to organize the administration in the territories occupied by Sabia. On 4 November 1919, Aleksandrov was arrested by the government of Aleksandar Stamboliyski but he succeeded to escape nine days later.

At the end of 1922, there was a bounty of 250,000 dinars placed on him by the Serbian authorities in Belgrade. In 1924 IMRO entered negotiations with the Comintern about collaboration between the communists 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. Todor Aleksandrov and Aleksandar Protogerov promptly denied through the Bulgarian press that
