Kedah (also known by its honorific, Darul Aman, or "Abode of Peace"[citation needed]) is a state of Malaysia, located in the northwestern part of Peninsular Malaysia. The state covers a total area of over 9,000 km², and it consists of the mainland and Langkawi. The mainland has a relatively flat terrain, which is used to grow rice. Langkawi is an archipelago of islands, most of which are uninhabited. Kedah was called Kadaram (Tamil:காடாரம்) by Tamil people and Syburi (Thai: ไทรบุรี; RTGS: Sai Buri) by the Siamese when it was under their influence.
