National Council (Polish: Rada Narodowa) was a local level of government in People's Republic of Poland. Introduced by Polish Constitution of 1952, they were elected for a term of office of 3 years in gminas, cities (and some districts), powiats and voivodships. National Councils had their own presidiums and were subordinate to higher-level National Councils.
They gave the socialist government democracy. In fact the elections were completely free, and National Councils had autonomy.
