Chak people

The Chaks (သက်, চাক), are a community inhabiting the Chittagong Hill Tracts of Bangladesh and also in Burma.

History
By the mid-13th century, the Saks had diverged from the Kadu people, who now reside in northwestern Myanmar's Sagaing Region. The Chaks entered the Chittagong Hill Tracts in the 14th century after their kingdom was overrun by the Arakanese. Despite this, there are still Chaks living in Arakan.
