On November 24, 1946, the first municipal elections in Belgium since the end of the Second World War were held. The Communist Party of Belgium (PCB-KPB), which had relatively little presence in the municipalities until then, achieved what would be its best electoral and political performance at this level. Based on the data collected, it appears that the PCB-KPB had candidates on the ballots of 865 communal elections and won 811 seats in total. Notably, it won twenty mayoral positions and 134 of its candidates were elected as aldermen in 123 communal majorities.
