In his revolutionary activity Delchev was guided by one thought: the Macedonian people must be organized and well armed, so that when the deciding moment arrived they might rise in revolt as one man against the tyranny of Abdul Hamid. "The liberation of Macedonia," wrote Delchev, "is possible only by an internal insurrection. Whoever thinks otherwise for the freedom of Macedonia, he fools himself and fools the others." Throughout his revolutionary career Delchev was guided solely by the interests of the Macedonian people as a whole regardless of race or creed.
In spite of the fact that in the Bulgarian schools of Salonica and Sofia he had been educated in the spirit of nationalism, Delchev looked upon all races in Macedonia as his brothers and fellow-countrymen. He was struggling for the freedom not only of the Macedonian Bulgars, but also of all nationalities inhabiting Macedonia (Bulgarians, Turks, Greeks, Roumanians, Albaninas, Gypsies, Jews etc.). He accepted and preached the principle pronounced by Gladstone "Macedonia for the Macedonians." Delchev was against the annexation of Macedonia to Bulgaria. When in the early period of the formation of the revolutionary movement, a current developed with purely nationalistic tendencies, Delchev was the first to oppose them. Energetically, with words and deeds, he opposed any movement which did not profess the unity and independence of Macedonia. "The purpose of the orgaization is,"said Delchev,"not to make Bulgarians or Greeks, but to work for freedom from the Turks and then let anybody become whatever he pleases." Delchev was a revolutionist Pro-Macedonian par excellence. He was not a hater of nationalities but despised those who oppress peoples-the tyrants-regardless of their nationality.
