In Povardarie, in late July 1906, lieutenant Pavle Blažarić-Bistrički was named the head of the mountain headquarters in Poreč replacing Nikola Janković-Kosovski and Panta Radosavljević-Dunavski.

In the First Balkan War, Blažarić was the commander of the Lukovo Chetnik Detachment which liberated the Christian population of Pristina from the Ottoman Turks in 1912.

In the Great War, he was appointed the commander of the 3rd Border Section with the task of preventing Albanian Kachaks and Bulgarian Komitadji (sponsored by IMRO/VMRO) from entering Serbia.

He gave "valuable data regarding the mood of the Serbian and Bulgarian army, commanders of individual units, soldiers on both sides."

And in them he admits that the local population in the town of Kavadarci in Vardar Macedonia and its surroundings offered mass armed resistance to the Serbian troops and assisted in one way or another the Bulgarian units fighting against them.
