Answer the following question: Information: - Lower Burma (also called Outer Myanmar) is a geographic region of Burma (Myanmar) and includes the low-lying Irrawaddy delta (Ayeyarwady, Bago and Yangon Regions), as well as coastal regions of the country (Rakhine and Mon States and Tanintharyi Region). - Wareru (; 12531307) was the founder of the Ramanya Kingdom located in today's Lower Burma (Myanmar). The kingdom is more commonly known as Kingdom of Hanthawady Pegu (Bago), or simply Pegu although the kingdom's first capital was Martaban (Mottama). By using both diplomatic and military skills, the commoner of Shan and Mon descent successfully carved out a kingdom for the Mon people in Lower Burma following the collapse of the Pagan Empire in 1287. Wareru was nominally a vassal of his father-in-law Ram Khamhaeng of Sukhothai, and of the Mongols, and successfully repulsed attacks by the Three Shan Brothers of Myinsaing in 1287 and 1294. - King Ram Khamhaeng (c. 1237/1247 1298) was the third king of the Phra Ruang dynasty, ruling the Sukhothai Kingdom (a forerunner of the modern kingdom of Thailand) from 12791298, during its most prosperous era. He is credited with the creation of the Thai alphabet and the firm establishment of Theravada Buddhism as the state religion of the kingdom. Recent scholarship has cast doubt on his role, however, noting that much of the information relating to his rule may have been fabricated in the 19th century in order to legitimize the Siamese state in the face of colonial threats. - Saw Zein ( Burmese : , pronounced : ( s zei ) ; 1303 -- 1330 ) was the fourth king of the Hanthawaddy Pegu from 1323 to 1330 . A nephew of the kingdom 's founder King Wareru , Saw Zein succeeded his brother King Saw O in September 1323 . He lost the southern territories of Tenasserim coast back to his nominal overlord Sukhothai , and looked to expand his territory northwards . He died in battle in his siege of Prome ( Pyay ) .
