Sylhet is the Northeastern division of Bangladesh, named for its main city, Sylhet.

Under British rule, it used to be a part of the Indian province of Assam. Having a Muslim majority, it was handed to Pakistan in 1947, and thus became part of Bangladesh when the former "East Pakistan" gained freedom.

In Bangladesh, the Sylhet area is known for its tea-gardens, its natural resources, and for its distinctive Sylheti dialect, difficult for other Bengali-speakers to follow.
