The Sultanate of Serdang (ﻛﺴﻠطﺎﻧﻦ سردڠ) was an early modern Malay-Indonesian monarchy, Serdang was founded in 1723 and joined the Republic of Indonesia in 1946. The Sultanate separated from the Sultanate of Deli after a dispute over the royal throne in 1720. Like other kingdoms on the east coast of Sumatra, Serdang prospered due to the opening of tobacco, rubber and oil palm plantations.
