Palembang is a city in the Northern area of Sumatra, Indonesia. It was once a Dutch colony, and later the seat of the Sultanate of Palembang. During Napoleonic Wars in 1812, the sultan at that time, Mahmud Badaruddin II repudiated British claims to suzerainty, which was responded by British by attacking Palembang, sacking the court, and installing sultan's more cooperative younger brother, Najamuddin to the throne.
