The monument was built in 1954 on the occasion of the 10th anniversary of the liberation by the Soviet Army, which is the general Russian interpretation of the complex military history of Bulgaria during World War II.

literally lifted from the article linked about the monument, even the invasion link goes on to talk about how the communist forces overthrew the government that were allied to the fucking nazis.

at least it mentions it's going to a museum instead of them destroying it I guess, sill very sad 🫗
