If any anarchism, and I count historical mutualism (Proudhon...) among these, were the dominant revolutionary ideology, then revolutionary ideologies would have been much more of a fringe phenomenon, and never haven gained such traction and hegemony as they did in the 20th century.
A Christian hegemony in revolutionary thinking would require a PoD before the French Revolution, I suspect. Progressive political philosophy of the 19th century was just so deeply anti-religious that I can`t see that happening. It would be perfectly logical with earlier PoDs, of course.
Nationalism can only be revolutionary until you`ve established your nation state. Then, it can perhaps turn into anti-imperialism, but as a state doctrine, that`s hardly revolutionary.
Fascism was always deeply reactionary, it was the petty bourgeoisie`s frightened reaction to the rise of the revolutionary left (both in socioeconomic field and in the field of religion, morality etc.).
I´ll go for a non-anarchist, non-Marxist Syndicalism therefore. Trade unions were a strong and growing force, and they were open to include almost everyone, appealing to older traditions (guilds and the like) as well as to the latest ideas around (universal participation). Having them fight for the takeover of economic AND political power could gain enough traction to become dominant. In fact, most socialist / working class movements in the late 19th century were a symbiosis between moderately Syndicalist unions and Marxist political thinkers. In some cases, the latter came to dominate the former, while in others, the former was dominant and shed its Syndicalism in favour of parliamentary reform agendas.
