[15] Aleksandrov was born in Novo Selo, Kosovo vilayet, the Ottoman Empire (present-day suburb of Štip, North Macedonia) to Aleksandar Poporushev and Marija Aleksandrova.
Aleksandrov, in co-operation with Todor Lazarov and Mishe Razvigorov, worked day and night to organize the Štip Revolutionary District.
On 10 January 1905, Aleksandrov's house was surrounded by numerous troops but he succeeded in breaking through the military cordoned and immediately joined the cheta (band) of Mishe Razvigorov where he became its secretary.
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.
In the spring of 1920, Aleksandrov went with a cheta (band) to Vardar Macedonia where he restored the revolutionary organization and attracted the world's attention to the unsolved Macedonian question.
[citation needed] In 1924 IMRO entered negotiations with the Comintern about collaboration between the communists and the creation of a united Macedonian movement.
[citation needed] 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 they have ever signed any agreements, claiming that the May Manifesto was a communist forgery.
On the other hand, other historians have referred to him as "the soul and the brain of the Macedonian resistance" and as "Macedonia’s Robin Hood", attributing to him remarkable organizational skills and will.
This incident caused Bulgarian president Georgi Parvanov to call upon the Macedonian government to review the history of Alexandrov's deeds on his meeting with Branko Crvenkovski in the town of Sandanski.
[28] In March 2021, the new Skopje municipal council majority by the Social Democratic Union of Macedonia decided to rename the names of many local sites.
[29] The former Skopje Mayor from VMRO-DPMNE Koce Trajanovski reacted that his successor Petre Šilegov has deleted part from the Macedonian history at the request of Bulgaria.
