Saw E Binnya

Saw E Binnya (, ; –1390) was governor of Tari from to 1387. Over his long tenure, he actively participated in two separate rebellions by his father Viceroy Laukpya of Myaungmya and his uncle Viceroy Byattaba of Martaban against their Martaban–Hanthawaddy overlords. It was during the second rebellion that he lost Tari in 1387, and was later assassinated by the Hanthawaddy commander Dein Mani-Yut in 1390.

Early life Saw E Binnya was born to a large powerful noble family in the Mon-speaking Martaban–Hanthawaddy Kingdom. He was the third child of Mwei Daw and Gov. Laukpya of Myaungmya, a half-cousin, once-removed of King Binnya U (r. 1348–1384). (Laukpya's father [E Binnya's paternal grandfather] Saw E Pyathat was a son of Smin E Kan-Kaung, a half-brother of King Saw Zein (r.) 1323–1330). King Binnya U was the only son of King Saw Zein and Queen Sanda Min Hla. (or 65) half siblings.

Circa early 1360s, he left his native Myaungmya to become governor of Tari (, ), a small district of just south of Donwun in the Martaban Province (modern Mon State and southern Kayin State). The appointment was made by the then reigning king Binnya U himself. The king had also wedded E Binnya to his half-niece Tala Thazain Saw Ngaik. E Binnya and Saw Ngaik were first cousins as she was a daughter of E Binnya's paternal elder uncle Byattaba and Princess Tala Mi Hsan. Through her mother, she was a granddaughter of King Saw Zein (r. 1323–1330) and Queen May Hnin Htapi of Martaban.

Career For the next twenty plus years, E Binnya would serve as a vassal ruler of Tari. However, his loyalties lay not with the king but with his uncle and his father. He would actively participate in his father's and uncle's two major rebellions against kings Binnya U and Razadarit.

First rebellion E Binnya was part of the rebellion that drove King Binnya U out of Martaban. In 1364, Byattaba seized control of the royal capital Martaban (Mottama) while the king and his retinue were away on a sojourn, searching for a white elephant. From the outset, E Binnya served as a senior commander in Byattaba's rebel force,

For the next dozen years, E Binnya's Tari became the de facto northern border of Byattaba's realm. To his north lay Donwun, which was governed by Smin Sam Lek, a Binnya U loyalist.

Second rebellion E Binnya's fief, Tari, was south of Donwun. His fort at Daybathwe was near Myaungmya, guarding the invasion route from Dala.

E Binnya again joined his uncle and his father when they raised another rebellion in 1384. The rebellion this time was against Binnya U's successor, Razadarit. His father Laukpya went on to invite the northern kingdom of Ava to invade their southern kingdom, and put him on the Hanthawaddy throne in 1385. This touched off the Ava–Hanthawaddy War (1385–1391). Although his overlord Byattaba was not officially part of the war, E Binnya decided to help his father, and went over to Myaungmya, by 1387. He left Baw Lagun, son of his paternal uncle E Bya-Bon, in charge of Tari. After all of Martaban fell to Razadarit's forces in late 1388 (or early 1389), Razadarit appointed one of his ministers to be governor of Tari, and the previous interim governor Than Byat to be governor of Donwun with the title of Byat Za.

By then, E Binnya had already resettled in his father's province. He had been put in charge of Daybathwe, a key fort near Myaungmya.

Death It was outside Daybathwe that E Binnya was assassinated in early 1390.

E Binnya found Dein's defection story credible. After all, the Hanthawaddy army had indeed just come off a disastrous defeat at the battle of Bassein (Pathein), and had retreated back to their base at Dala (Twante). Dein's regiment was the only Hanthawaddy rearguard force remaining in the Myaungmya province.

At any rate, he agreed to Dein's request to personally take Dein in, outside the gates of Daybathwe. On the agreed upon day, E Binnya waited by the gates on his war elephant, accompanied by 20 guards. When he saw that Dein also on his war elephant was approaching with 100 guards, E Binnya asked Dein to come forward alone. After Dein ordered his men to stay behind, E Binnya allowed Dein's elephant to get near his elephant. It was a mistake. When their elephants were side-by-side, Dein then suddenly jumped over to E Binnya's elephant, and killed him.
