Myeik (, mjeɪʔ or beɪʔ; ဗိက်, pòik; มะริด, , má(ʔ).rít; formerly Mergui, mɜːrˈɡwiː) is a rural city in Tanintharyi Region in Myanmar (Burma), located in the extreme south of the country on the coast off an island on the Andaman Sea. , the estimated population was over 209,000. Myeik is the largest city in Tanintharyi Region, and serves as the regional headquarters of Myanmar Navy's Tanintharyi Regional Command. The area inland from the city is a major smuggling corridor into Thailand. The Singkhon Pass, also known as the Maw-daung Pass, has an international cross-border checkpoint. Myeik was the southernmost part of the Pagan Kingdom between the 11th and 13th centuries. After the Pagan Empire's collapse in 1287, Myeik became part of successive Thai kingdoms from the late 13th century to the middle of 18th century: first the Sukhothai Kingdom and later the Ayutthaya Kingdom. A brief period of Burmese rule interrupted this between 1564 and 1593. From the 16th century on, the city was an important seaport and trading center with the Europeans, who would land at Mergui, travel upriver to Tenasserim and then cross the mountains to reach Ayutthaya. The French officer Chevalier de Beauregard was made Governor of the city of Myeik after the Anglo-Siamese War (1687) that resulted in the English being expelled from Siam. De Beauregard was named Governor by Narai, the king of the Ayutthaya Kingdom, replacing an Englishman, Samuel White. The French were then expelled from Myeik following the Siamese revolution of 1688. The Burmese captured Myeik in 1765 as part of an invasion that would ultimately topple the Ayutthaya Kingdom in 1767. In 1826, the Burmese ceded the region to the British after the First Anglo-Burmese War (1824–1826). In the Pacific Theater of World War II, Imperial Japanese forces used laborers to construct the Mergui Road to aid their retreat after rail line were destroyed by Allied bombings. Myeik has a tropical monsoon climate (Köppen climate classification Am) that is hot throughout the year.
