Has Mao had a greater historical impact than Lenin? Obviously Mao built from Lenin, but if you look at the lasting socialist states and contemporary struggles for socialist states, history seems to be more in line with a Maoist conception.
The most glaring example is China, now almost the most powerful nation, regardless of whether you think its socialism or not, but consider that temporary allegiances with the national bourgeois in the name of the goal of national liberation is part of Mao's thought.
In the current day, there are several ongoing armed communist insurgencies around the world, nearly all of them are Maoist. The Naxalites, The New Peoples Army in the Philippines.
Rojava, called anarchist by some, has its roots as a Protracted Peoples War for national liberation.
While the zapatistas do not claim roots in Maoism, their struggle looks almost identical to that of other Maoist groups.
Mao also had a huge influence on othe rLatin American struggles, in Columbia, Peru, even the Che and FIdel were heavily influenced by Mao.
The largest armed communist group in US history, the Black Panther Party, was mainly influenced by Mao, the free breakfast programs an attempt to "serve the people" as Mao instructed.
