One party won this state's first assembly election, by a landslide.

The Indian National Congress won 149 of the 238 seats up for election in West Bengal, a clear majority in the young assembly.

It took 38.8% of the vote share — the slice of all ballots cast that went to one party or candidate — well ahead of the Communist Party of India in second, on 10.8%.

This was also the state's first constituency map.

Drawing it is called delimitation — the official redrawing of constituency boundaries, which happens every so often as India's population shifts.

Some constituencies also sent more than one member to the state legislature at once.

51 of the 187 constituencies worked this way that year.

Altogether 238 people were elected to the assembly, more than the number of constituencies themselves.

A few numbers from that first count stand out.

The closest race: Muchipara, West Bengal was decided by just 9 votes — the smallest margin, how far ahead the winner finished, in votes, over whoever came second, of any seat that year.

Baraset, West Bengal saw the widest gap of the night, with 75.0% of the vote separating the top two candidates.

Turnout — the share of registered voters who actually cast a ballot — ran as high as 75.4% in Sutahata, West Bengal.

The single largest electorate belonged to Arambagh, West Bengal, with 1,19,109 registered voters.

This state's electoral history begins here — every later comparison in this project's own record starts from this first count.
