The Langkat Sultanate was a historical Malay state located in what is now North Sumatra, Indonesia. Established in the 17th century, it was known for its rich cultural heritage and strategic position along trade routes. The sultanate played a significant role in regional politics and was influenced by both Islamic and local traditions. The capital of the Langkat Sultanate was Stabat, which served as a center for administration and commerce. The sultanate maintained relationships with neighboring states and European powers, contributing to its prominence in the region until the Dutch colonial period, which led to its decline.
