The Maoist uprising only occurred within the last 20 years, starting around 1996 and the monarchy was abolished in 2006. There were a lot of concessions made for this to happen and restrictions put on the most militant Maoists to re-integrate them into society and work with them through political processes instead of further violence. They've been ruled by a Democratic coalition government for a while that includes a few different communist groups. But they aren't a wholly socialist country and there's still elements of monarchism and things like that.

As other posters have said yeah the communist uprising and now coalition state have outlawed slavery and sought restitution from the Monastery system for it, outlawed the monarchy, and additionally the quality of life significantly went up especially child and maternal health. Also don't feel bad about asking questions leftists love answering questions
