Kelantan is a state of Malaysia. The capital and royal seat is Kota Bharu.Due to Kelantan's relative isolation and largely rural lifestyle, Kelantanese culture differs somewhat from Malay culture in the rest of the peninsula; this is reflected in the cuisine, arts and the unique Kelantanese Malay language, which is unintelligible even for some speakers of standard Malay.Early Kelantan had links to the Funan Kingdom, the Khmer Empire, Sri Vijaya, Majapahit and Siam. Around 1411, Raja Kumar, the ruler of Kelantan, became independent of Siam, and Kelantan became an important centre of trade by the end of the 15th century.For centuries, Kelantan was all but separated from the rest of the country by the Titiwangsa Mountains, a mountain range running from north to south through the peninsula. Weeks of hard travel were required to reach Kelantan. The "easy way" to Kelantan was to sail around the peninsula, braving the sea and pirates. For this reason Kelantan's history often involves the sea, and boats. Even today, many of its people are very much tied to the sea. A discussion with many coastal residents will confirm that their ancestors, as far back as they know, were "of the sea."
