What is the essence of a revolution, its leading class or the social essence it overthrew?
Of course it depends on the result! The result of the February Revolution was to overthrow the feudal government of the Tsar, and the task of anti-feudalism was generally accomplished by the bourgeoisie, so it was called the bourgeois democratic revolution. But for some reason, the Russian feudal government was overthrown by the proletariat, so the February Revolution was a bourgeois democratic revolution led by the proletariat! ! !
