AD) this people is declaring himself as Bulgarians. After Macedonia is fallen under Serbian rule (1913), with terror and pressure people are forced to call himself "south-serbians" or "serbians". After this doctrine is failed, Serbia makes a new one: the macedonian doctrine. People are called "macedonians". The macedonian language differs from bulgarian mainly in some serbian word, involve into it.
