Kedah (Malay pronunciation: [kəˈdɑh]; Jawi: قدح), also known by its honorific Darul Aman or "Abode of Peace" 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 the Langkawi islands. The mainland has a relatively flat terrain, which is used to grow rice, while Langkawi is an archipelago, most of which are uninhabited islands. Kedah was previously known as Kadaram (Tamil: கடாரம்; kadāram) by the ancient and medieval Tamils, Kataha or Kalahbar (Arabic: قتح; qataḥa or Arabic: قلحبر; qalaḥbar) by the Arabs, and Syburi (Thai: ไทรบุรี; RTGS: Sai Buri) by the Siamese when it was under their influence. To the north, Kedah borders the state of Perlis and shares an international boundary with the Songkhla and Yala provinces of Thailand. It borders the states of Perak to the south and Penang to the southwest. The state's capital is Alor Setar and the royal seat is in Anak Bukit. Other major towns include Sungai Petani, and Kulim on the mainland, and Kuah on Langkawi.
