In fact, initially the real aim of Garvanov was to take over the IMRO, and thus prevent the early outbreak of an uprising which he believed would bring disaster upon the population.

As president of the Central Committee, he convened in January 1903 a congress in Thessaloniki, that resolved to launch an uprising against the Ottomans.

The Centralists' majority was convinced that if the Organization would unleash an uprising, Bulgaria would declare war of the Ottomans and after the subsequent intervention of the Great Powers the Empire would collapse.

The left-wing faction warned against the risks of such unrealistic plans, opposing the uprising as inappropriate as tactics and premature by time.

Garvanov, along with Boris Sarafov was killed by Todor Panitsa, close to the left wing leader of IMARO Yane Sandanski, in 1907.
