Natshinnaung (, ; 1579âÂÂ1613) was a Toungoo prince and poet known for leading a rebellion in Thanlyin (Syriam) alongside Portuguese mercenary Filipe de Brito.
A grandson of King Bayinnaung and the eldest son of Minye Thihathu, Viceroy of Toungoo, Natshinnaung participated in King Nanda Bayin's campaigns to reconquer Siam in the early 1590s, and took part in the sacking of Nanda's capital Pegu in 1599. On , he married his lifelong love, Princess Yaza Datu Kalaya, for whom his famous poems were written. The marriage was cut short, however, as the princess died only seven months later.
When Natshinnaung succeeded his father on 11 August 1609, much of the country had been reunited under the leadership of his cousin Anaukpetlun, who attacked Toungoo in 1610. Although Natshinnaung was made viceroy of Toungoo as the city surrendered on 4 September that same year (2nd waning of Tawthalin 972 ME), he was deeply dissatisfied with his reduced status and allied with Filipe de Brito to commence a counter-offensive that ultimately failed. Both were executed afterwards upon the fall of Thanlyin, De Brito's domain, to Anaukpetlun's forces.
Natshinnaung had six sons and three daughters from five concubines, but no children came from his marriage with Yaza Datu Kalaya.
Natshinnaung is considered by many to be the greatest yadu () (a classical genre of poetry) poet in Burmese history. Many of his works are dedicated to Princess Yaza Datu Kalyani. The themes of his poetry were often of love, nature, and war. Natshinnaung employed the use of vocabulary and rhymes in his works. In addition, he was a warrior, who advanced many military strategies and tactics of Burma. Some of his yadu poems describe the infantry and the elephant troops. It has been claimed that Natshinnaung sent his poems to Yaza Datu Kalyani through the usage of a parrot. He wrote all of his works during his youth.
Later in life, Natshinnaung focused on obtaining power for his kingdom. His poems on war are said to have been based on his experiences as a young prince.
