context_page_description: Bayinnaung Kyawhtin Nawrahta was king of the Toungoo Dynasty of Burma from 1550 to 1581. During his 31-year reign, which has been called the "greatest explosion of human energy ever seen in Burma", Bayinnaung assembled what was probably the largest empire in the history of Southeast Asia, which included much of modern-day Burma, the Chinese Shan states, Lan Na, Lan Xang, Manipur and Siam.
  Although he is best remembered for his empire building, Bayinnaung's greatest legacy was his integration of the Shan states into the Irrawaddy-valley-based kingdoms. After the conquest of the Shan states in 1557–1563, the king put in an administrative system that reduced the power of hereditary Shan saophas, and brought Shan customs in line with low-land norms. It eliminated the threat of Shan raids into Upper Burma, an overhanging concern to Upper Burma since the late 13th century. His Shan policy was followed by Burmese kings right up to the final fall of the kingdom to the British in 1885.
  Bayinnaung could not replicate this administrative policy everywhere in his far flung empire, however.
context_section_description: Tabinshwehti's decision would pay enormous dividends in the following years. Between 1534 and 1549, Toungoo would bring war to all its neighbors and in the process found the largest polity in Burma since the fall of Pagan in 1287. Ye Htut would win many key battles for his king, and help administer the growing kingdom.
  In late 1534, Toungoo attacked Hanthawaddy, the larger, wealthier but disunited kingdom to their south. It was Toungoo's gambit to break out of its narrow landlocked realm before the Confederation's attention turned to the last remaining holdout in Upper Burma. While Toungoo did not yet have any foreign firearms, due to receiving a constant flow of refugees from elsewhere in Upper Burma for the last three decades, Toungoo did have more manpower than it normally could have enlisted.
  Tabinshwehti and Ye Htut (now styled as Kyawhtin Nawrahta) were to cut their teeth in failure however. Their maiden annual dry-season campaigns (1534–1537) all failed against Pegu's well armed, heavily fortified defenses. But their performance got better with each successive campaign, penetrating deeper and deeper into Hanthawaddy territory. They finally broke through in their 1538–1539 campaign, and captured Pegu. Kyawhtin Nawrahta made his name in the Battle of Naungyo in which his light forces decisively defeated numerically superior Hanthawaddy forces in the Irrawaddy delta. The battle, one of the most famous in Burmese military history, has been called "the first characteristic touch" of the great Bayinnaung. After the battle, a grateful Tabinshwehti bestowed his brother-in-law the title of Bayinnaung ("King's Elder Brother"), the name by which he would be remembered.
  Toungoo went on to conquer all of Hanthawaddy by mid-1541, gaining complete control of Lower Burma's manpower, access to foreign firearms and maritime wealth to pay for them. And Tabinshwehti would use these new assets for further expansions. By incorporating Portuguese mercenaries, firearms and military tactics into the Toungoo armed forces, Tabinshwehti and Bayinnaung continued to grow as military leaders. The duo also benefited from having experienced former Hanthawaddy military commanders like Saw Lagun Ein and Smim Payu serve as their top military advisers and generals. With their help, Bayinnaung delivered key decisive victories at the Battle of Padaung Pass (1542) against Prome's ally Arakan and the Battle of Salin (1544) against the Confederation, enabling Toungoo to take over central Burma as far north as Pagan (Bagan). After Bayinnaung crushed the Arakanese forces in April 1542, Tabinshwehti was so pleased with the victory that he made Bayinnaung the heir-apparent of the kingdom.
  The duo's later campaigns against Arakan (1545–1547) and Siam (1547–1549) however fell short. In both campaigns, Toungoo forces won all major open battles, and went on to lay siege to the capitals, Mrauk-U and Ayutthaya respectively. But they still had no answer to heavily fortified defenses equipped with Portuguese firearms, and had to retreat both times. Toungoo's own Portuguese supplied cannon had little impact on the walls of both capitals. Nor did they have enough manpower (19,000 and 12,000 troops respectively in the Arakanese and Siamese campaigns) for long-term sieges. Nonetheless, despite the setbacks, Tabinshwehti and Bayinnaung had by 1549 built up the largest polity in Burma since the fall of the Pagan Empire in 1287, stretching from Pagan in the north to Tavoy in the south.
