Bayinnaung Kyawhtin Nawrahta (; ; 16 January 1516 – 10 October 1581) was King of Burma from 30 April 1550 until his death in 1581, during the Toungoo dynasty. His reign is considered one of the most momentous in Burmese history, famously described as "the greatest explosion of human energy ever seen in Burma". During his rule, he assembled the largest empire in Southeast Asian history,(Lieberman 2003: 152) which encompassed much of present-day Myanmar, as well as the Shan States, Lan Na, Lan Xang, Manipur, and the Ayutthaya Kingdom.

Though best remembered for his empire-building, Bayinnaung's most enduring legacy was the integration of the Shan States into the Irrawaddy valley administrative system. After conquering the Shan States between 1557 and 1563, he implemented a series of administrative reforms aimed at reducing the power of hereditary rulers, known as saophas, and aligning Shan governance and customs with lowland Burmese norms. These reforms effectively eliminated the persistent threat of Shan raids into Upper Burma, a source of instability since the 13th century. Bayinnaung's integration policy served as a model for successive Burmese monarchs, who continued his approach until 1885.

However, Bayinnaung largely followed the prevailing Mandala administrative model across his vast and culturally diverse empire. His rule over the First Toungoo Empire was described as "an emperor without an empire" holding control through personal allegiance to Bayinnaung as a Chakravartin (Universal Monarch) from it sub-kingdoms, rather than to any institutions. While this loyalty endured during his lifetime, it rapidly unraveled after his death in 1581. Both the kingdoms of Ava and Ayutthaya revolted within just over two years, and by 1599, all vassal states had declared independence, resulting in the complete collapse of the empire.

Bayinnaung is regarded as one of the three greatest Burmese monarchs and is commemorated with major landmarks in his name in modern Myanmar. He is also well known in Thailand, where he is remembered as "Conqueror of the Ten Directions". Despite being a former adversary of Ayutthaya, his influence in Thai historical consciousness stands as a testament to the scale and power of his reign.

Early life

Ancestry

The future king Bayinnaung was born Ye Htut (ရဲထွတ်, ) on 16 January 1516 to Mingyi Swe and Shin Myo Myat. His exact ancestry is unclear. No extant contemporary records, including Hanthawaddy Hsinbyushin Ayedawbon, the extensive chronicle of the king's reign written two years before his death, mention his ancestry.Thaw Kaung 2010: 102–103 It was only in 1724, some 143 years after the king's death, that Maha Yazawin, the official chronicle of the Taungoo Dynasty, first proclaimed his genealogy.

According to Maha Yazawin, he was born to a gentry family in Toungoo (Taungoo), then a former vassal state of the Ava Kingdom. He was descended from viceroys of Toungoo Tarabya (r. 1440–1446) and Minkhaung I (r. 1446–1451) on his father's side; and from King Thihathu of Pinya (r. 1310–1325) and his chief queen Mi Saw U of the Pagan Dynasty on his mother's side.Thaw Kaung 2010: 118–119 Furthermore, Ye Htut was distantly related to then presiding ruler of Toungoo Mingyi Nyo and his son Tabinshwehti through their common ancestor, Tarabya I of Pakhan.(Hmannan Vol. 2 2003: 171): Mingyi Nyo's maternal grandmother Min Hla Htut, Princess of Pyakaung, was a daughter of Minye Kyawswa and Saw Min Hla, daughter of Tarabya of Pakhan. Later chronicles simply repeat Maha Yazawin account. In all, the chronicles (perhaps too) neatly tie his ancestry to all the previous main dynasties that existed in Upper Burma: the Ava, Sagaing, Myinsaing–Pinya and Pagan dynasties.

Despite the official version of royal descent, oral traditions speak of a decidedly less grandiose genealogy: that his parents were commoners from Ngathayauk in Pagan district or Htihlaing village in Toungoo district, and that his father was a toddy palm tree climber, then one of the lowest professions in Burmese society. The commoner origin narrative first gained prominence in the early 20th century during the British colonial period as nationalist writers like Po Kya promoted it as proof that even a son of a toddy tree climber could rise to become the great emperor in Burmese society.Thaw Kaung 2010: 104–105 To be sure, the chronicle and oral traditions need not be mutually exclusive, since being a toddy tree climber does not preclude his having royal ancestors.(Harvey 1925: 342): While "the family trees sported by men after they attain greatness must be suspect", Swe being "a toddy climber no more precludes the possibility of his having royal ancestors than it precluded his becoming vassal king of Toungoo when his son rose to greatness".

Childhood and education Whatever their origin and station in life may have been, both of his parents were chosen to be part of the seven-person staff to take care of the royal baby Tabinshwehti in April 1516. Ye Htut's mother was chosen to be the wet nurse of the prince and heir apparent. The family moved into the Toungoo Palace precincts, where the couple had three more sons, the last of whom died young. Ye Htut had an elder sister Khin Hpone Soe, and three younger brothers: Minye Sithu, Thado Dhamma Yaza II, and the youngest who died young. He also had two half-brothers, Minkhaung II and Thado Minsaw, who were born to his aunt (his mother's younger sister) and his father.Sein Lwin Lay 2006: 247–248

Ye Htut grew up playing with the prince and the king's other children, including Princess Thakin Gyi, who would later become his chief queen. He was educated in the palace along with the prince and the other children. King Mingyi Nyo required his son to receive an education in military arts. Tabinshwehti along with Ye Htut and other young men at the palace received training in martial arts, horseback riding, elephant riding, and military strategy.Sein Lwin Lay 2006: 109 Ye Htut became the prince's right-hand man.Sein Lwin Lay 2006: 99–100

Deputy of Tabinshwehti

Rise to power On 24 November 1530, Mingyi Nyo died and Tabinshwehti ascended the throne.Hmannan Vol. 2 2003: 183 The 14-year-old new king took Ye Htut's elder sister Khin Hpone Soe as one of his two principal queens, and rewarded his childhood staff and friends with royal titles and positions. Ye Htut, already a close confidant of the new king, instantly became a powerful figure in the kingdom which was surrounded by increasingly hostile states.Sein Lwin Lay 2006: 126–127 In the north, the Confederation of Shan States had conquered the Ava Kingdom just three and a half years earlier. To the west was the Confederation's ally the Prome Kingdom. To the south lay the Hanthawaddy kingdom, the wealthiest and most powerful of all post-Pagan kingdoms. The impending threat became more urgent after the Confederation defeated its former ally Prome in 1532–1533. Tabinshwehti and the Toungoo leadership concluded that their kingdom "had to act quickly if it wished to avoid being swallowed up" by the Confederation.Fernquest 2005: 356

It was during the kingdom's mobilizations that Ye Htut made his mark, and was noticed for "his deeds of valor and strength of character".Htin Aung 1967: 105–106 Ye Htut was by the king's side in 1532 when the king and his 500 most skillful horsemen made an uninvited foray into the Shwemawdaw Pagoda at the outskirts of Pegu, the capital of Hanthawaddy, ostensibly for the king's ear-piercing ceremony. The audacious intrusion went unpunished by Hanthawaddy's weak ruler, King Takayutpi. Ye Htut became the constant companion and adviser to the young king.

However, the close relationship between the two was severely tested in 1534, as they prepared for war against Hanthawaddy. Ye Htut had become romantically involved with Thakin Gyi, the king's younger half-sister, and the affair was discovered around April 1534.Chronicles (Maha Yazawin Vol. 3 2006: 75) and (Hmannan Vol. 3 2003: 61) only give 896 ME (29 March 1534 to 29 March 1535) for the date of the marriage between Bayinnaung and Thakin Gyi (Atula Thiri). But they must have got married in early 896 ME around April 1534 since the couple had their second child, Nanda Bayin, in November 1535. The commoner's affair with the king's sister under Burmese law constituted an act of treason. Ye Htut spurned suggestions of mutiny and submitted to arrest. Tabinshwehti deliberated at length with his ministers, and finally came to the conclusion that Ye Htut should be given his sister in marriage, and a princely title of Kyawhtin Nawrahta. With this decision, Tabinshwehti won the loyalty of his brother-in-law "without parallel in Burmese history".Htin Aung 1967: 106

Military leadership

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.Harvey 1925: 153

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.Harvey 1925: 154–155 After the battle, a grateful Tabinshwehti bestowed upon his brother-in-law the title of Bayinnaung ("King's Elder Brother"), the name by which he would be remembered.Hmannan Vol. 2 2003: 193

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 ArakanHmannan Vol. 2 2003: 213 and the Battle of Salin (1544) against the Confederation, enabling Toungoo to take over central Burma as far north as Pagan (Bagan).Hmannan Vol. 2 2003: 220–222 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.Hmannan Vol. 2 2003: 209–211
