>What happened to architecture
In Hungary, the pattern was like this:
In the 20s, the government pushed Neo-Baroque as the preferred architecture style instead of Art Deco. This was due to political reasons, the US was an entente power, and the government didn't want anything from countries that fucked up Hungary after WWI.
So they sent the architects to German schools, where Bauhaus started, which started the slippery slope, bauhaus became the main architecture style in the 30s, with a national undertone (coat of arms/soldier murals on the buildings, etc.). 30s Bauhaus was simple, but symmetrical, it was kind of nice in its own way.
After the commies toke over, the real chaos begun: Stalinism was the only accepted style, but the Hungarian architects didn't know what Stalinism was, so they mixed Classicism and Modernism. After Stalin's death, modernism/brutalism became the only preferred style commieblock constructions started, and "experimental" apartments were built. Domes and ornaments were destroyed on old houses, due to political reasons.
In the 90s, there was a split in Hungarian architecture: Some preferred a more conservative/organic architecture style, and others wanted to push the Western modernist/post-modern style.
After 2010, (most likely due to pressure form the government) extreme architecture styles were stopped, only cube/traditional shaped buildings are accepted, while there's a push for traditional reconstructions.
in short: things started to go shit in the 30s, and this process was accelerated by the commies.
