Pulau Tiga, near Laguna Merbok was once the location of His Highness Sultan Ahmad Tajuddin's palace and his headquarters after being defeated and drove away by the Siamese in the Battle for Kuala Kedah Fort in the 18th. century. For not so long after, the Siamese attacked the new palace and razed it down. The Sultan escaped to Penang and then Malacca. Kedah was then broken into several administrative territories and ruled by respective Siamese Military Governors. A few years later, after a peace negotiation, the Siamese agreed to re-install His Highness as the Sultan of Kedah with a new throne at the Kuala Muda Fort. The smaller territories were then merged back as Kedah state with the military governors replaced by a Siamese Resident Advisor.
