Speaking as Buddhist, Buddhism def has some reactionary strains, but interestingly also some hardcore anti-imperialist ones in the modern era too, especially in Sri Lanka.

I highly recommend reading a history of christian imperialism in sri lanka, by Walpola Rahula (a buddhist socialist who wrote probably the most famous modern primer on Buddhism, What the Buddha taught), called the heritage of the bhikkhu. It also gets into why Christians tried to depoliticize and de-fang the buddhist monastic movement, to silence it from making criticisms of european imperialism.

Unfortunately most of christianity's anti-imperialist / anti-landlord strains died out by the middle ages, but there even are some in the modern era, like liberation theologists, and some anti-war christians.
