Information: - Athinhkaya Saw Yun (; also spelled Sawyun; 1299 5 February 1327) was the founder of the Sagaing Kingdom of Myanmar (Burma). The eldest son of King Thihathu set up a rival kingdom in 1315 after Thihathu appointed Uzana I as heir-apparent. Saw Yun successfully resisted two small expeditions by Pinya by 1317. While Saw Yun nominally remained loyal to his father, he was the de facto king of the area roughly corresponding to present-day Sagaing Region and northern Mandalay Region. - Pinya, or Vijayapura, was the capital of the Kingdom of Pinya, located near Ava, Mandalay Region, Myanmar. It was the residence of the Pinya dynasty who ruled this part of central Myanmar from 1313 to 1365. It was founded by King Thihathu as Wizayapura on 7 February 1313. - The Sagaing Kingdom was a small kingdom ruled by a junior branch of the Myinsaing dynasty from 1315 to 1365. Originally the northern province of Sagaing of the Pinya Kingdom, it became de facto independent after Prince Saw Yun successfully fought for autonomy from his father King Thihathu in 131517. Sagaing formally seceded from Pinya in 1325 after Thihathu's death. - See Kyaswa for the king of Pagan of the same name . Kyaswa of Sagaing ( Burmese : ( ) , pronounced : ( tazwa ) ; also known as Kyawswa ; 1323 -- 1349 ) was king of Sagaing from 1339 to 1349 . The eldest son of King Saw Yun was put on the throne by Chief Minister Nandapangyan . The chief minister had killed King Tarabya I , who in turn had organized to have King Shwetaungtet killed . Prior to becoming king , he , along with his brothers , spent about four years in hiding in Mindon , away from Shwetaungtet who had seized the throne in 1335/36 by imprisoning his father Tarabya I. But in 1339 , they were captured and brought back to Sagaing . Meanwhile , Tarabya I planned to kill Shwetaungtet from prison . One of his queens was Saw Pa Oh , daughter of King Uzana I of Pinya . Their daughter was later married to King Uzana II of Pinya . - Thihathu (; 12651325) was a co-founder of the Myinsaing Kingdom, and the founder of the Pinya Kingdom in today's central Burma (Myanmar). Thihathu was the youngest and most ambitious of the three brothers that successfully defended central Burma from Mongol invasions in 1287 and in 130001. He and his brothers toppled the regime at Pagan in 1297, and co-ruled central Burma. After his eldest brother Athinkhaya's death in 1310, Thihathu pushed aside the middle brother Yazathingyan, and took over as the sole ruler of central Burma. His decision to designate his adopted son Uzana I heir-apparent caused his eldest biological son, Saw Yun to set up a rival power center in Sagaing in 1315. Although Saw Yun nominally remained loyal to his father, after Thihathu's death in 1325, the two houses of Myinsaing officially became rival kingdoms in central Burma. What is the relationship between 'kyaswa of sagaing' and 'sawyun'?
