Until recently I had never heard of #Vanguardism - I came across that term when I heard about #OrishaLand.

Heres the definition from #400and1 400 s page
https://www.fourhundredandone.com/so/ebNUVWIan#/main :

Vanguardism is a strategy that has been successfully leveraged by revolutionaries, historically. A vanguard party is a collective that is organized hierarchically. Its job is to seize power on behalf of the masses in order to establish a socialist state. (A socialist state is an organized collective that distributes resources equitably and universally.)
