Kolkata: Nearly 79 years after legislators from western Bengal voted to join India, paving the way for the creation of West Bengal, June 20 has re-emerged as a potent political symbol, reopening old debates over Partition, identity and historical memory.As the BJP government marks Paschimbanga Divas with official ceremonies across the state for the first time on this date, the observance has evolved from a largely forgotten date into a political marker in a wider contest over how Bengal remembers its birth and defines its identity.Read more: PM Modi to mark Paschimbanga Divas, lead Yoga Day events in KolkataUnlike most states whose foundation days commemorate linguistic aspirations or administrative reorganisation, West Bengal was born amid the upheaval of partition, communal violence and mass migration.

That history, long relegated to the margins of public discourse, has acquired fresh political resonance under the BJP, which sees June 20 as a defining moment in the state's journey within the Indian Union.For the BJP, the day symbolises the campaign led by Syama Prasad Mookerjee that ultimately led to the state's formation.

Its critics, however, see the observance as an attempt to reinterpret a complex historical process through a contemporary ideological lens.The significance of June 20 lies in the events of 1947, when legislators from the western districts of undivided Bengal voted in favour of partition and joining India, a decision that laid the foundation for the state that emerged after Independence.Yet the debate over Paschimbanga Divas is no longer confined to history.
