3. History of Sundarbans
Ancient History
The Sundarbans has been shaped by centuries of river movement and sediment deposition from the Ganga, Brahmaputra and Meghna rivers.
For thousands of years, the region remained covered with dense mangrove forests due to its difficult terrain, tidal movements and harsh environmental conditions.
Early communities depended on the rivers and forests for fishing, honey collection and natural resources.
British Period
During British rule, systematic surveys and forest management began in the Sundarbans.
The British administration classified large parts of the region as forest reserves to control timber resources and manage land.
However, human settlements expanded gradually as people cleared parts of the forest for agriculture and established villages.
