He finished the Serbian theological school in Prizren, and started teaching in the Oreše village near Veles.

Because of hectic guerilla warfare and exhaustion, Radivojević and his band were returned to Serbia in late 1906, where they vacated until spring 1907.

At this time, the Internal Macedonian Revolutionary Organization (IMRO) decided on a major offensive against the Serbian bands on the right side of the Vardar.

An IMRO unit of 130 fighters under the command of several Bulgarian officers set off against Poreče and Azot to destroy Serbian bands and villages.

The local Serbian bands were weakened and diminished by the constant warfare, thus, in March 1907 when the Ottoman troops proved strong in the Kumanovo region, Radivojević and his band were sent across Kosovo as aid, and were all wearing Albanian clothes with the plan to reach Poreče disguised as Albanian kachaks.
