West Bengal Foundation Day: History, Facts, Timeline & Its Lasting Significance
West Bengal, a culturally vibrant and historically rich state of India, observes West Bengal Foundation Day every year to mark a significant and somewhat painful chapter of Indian history. Unlike other state foundation days that are widely celebrated with pride, West Bengal’s origin story is embedded in the complex emotional aftermath of Partition, where division, displacement, and identity crisis deeply affected the region.
In this article, we explore everything about West Bengal Foundation Day — from its origin and timeline to its significance, societal impact, and why it’s still a controversial yet essential remembrance in today’s India.
📜 History of West Bengal Foundation Day
The story of West Bengal begins on 20th June 1947 — a date that remains etched in the memories of those affected by the brutal reality of Partition.
✅ Why was this date chosen?
The British Parliament’s Indian Independence Act of 1947 mandated the division of British India into two dominions — India and Pakistan. This led to the partition of Bengal into:
-
West Bengal (part of India)
-
East Bengal (later East Pakistan, now Bangladesh)
On 20th June 1947, the Bengal Legislative Assembly held a historic vote. It was decided that Bengal would be divided along religious lines. Hindu-majority areas would remain in India as West Bengal, while Muslim-majority areas would go to Pakistan as East Bengal.
This marked the formal foundation of West Bengal as a state of India.
