History
Comparative Study of Unicameral versus Bicameral Post-Communist Legislatures
Quick fact
Most post-communist countries in Central and Eastern Europe adopted unicameral legislatures, but Hungary and Poland chose bicameralism—Poland's Senate survived from its past, while Hungary created a new second chamber.
Why this is interesting
Ever notice that some countries have one parliament and others have two? After communism fell, nearly every country in Eastern Europe had to decide, and their choices still affect how laws are made today.
