Not in my opinion. I dont think forcing yourself upon others and establishing totalitarian states is a success. If you mean working as becoming the main party then sure but i think working is establishing its principles. And there are anarchistic projects that worked quite well im that sense. They never lastet but they did often change a lot. For example the spanish civil war, the paris kommune. Those are the biggest ones. But anarchistic principles were always important. Many “primitive” cultures were egalitarian ones, which they did a lot to keep it that way.
