Simeulue
Simeulue lies in the Indian Ocean off the western coast of northern Sumatra. Hills run through its interior, while villages occupy the coast and valleys. Its inhabitants speak languages including Devayan and Sigulai, distinct from those of the nearby mainland. Local tradition credits Tengku Di with bringing Islam to the island in the seventeenth century and founding a mosque at Salur. Across the sea, the island maintained connections with the wider Acehnese and Sumatran world.
