Both Binnya Kyan and Binnya Law had been childhood tutors of Takayupti, and are absolutely devoted to him.

Nonetheless, both ministers are executed in 1538 by the young king, who believes Toungoo's misinformation that the ministers are Toungoo moles.

After their death, the king finds himself helpless.

When Toungoo forces arrive once again in late 1538, he decides, rather than fight, to flee Pegu for the Prome Kingdom, where another brother-in-law of his, Narapati of Prome, is king.

(He does not retreat to Martaban, which is nominally still part of Hanthawaddy because he does not trust its governor Saw Binnya.)

The Toungoo forces take the Mon capital without firing a shot.

The city of Oradea, or Nagyvárad, had been captured by the Turks in 1474 after a protracted siege.

Their mostly tolerant policies towards others peoples ensured that the city has become an ethnic mosaic of Romanians, Hungarians, Austrians, Slovaks, Hebrews, Ruthenians and Turks, causing Oradea to grow as an urban area starting with the sixteenth century.

After the Ottoman invasion of Hungary in the first third of the sixteenth century, the city has become a constant point of contention between the Principality of Transylvania, the Ottoman Empire and the Habsburg Monarchy.

The Peace of Várad, mediated in 1538 by Zápolya's adviser, the Paulist bishop György Martinuzzi (Juraj Utje-senovic, “Friar George”), is concluded between Emperor Ferdinand I and John Zápolya here on February 4, 1538, in which they mutually recognize each other as legitimate monarchs of a divided Hungary.

Ottoman naval power is felt at this time even as far afield as India, where a fleet sent out from Egypt assist the Gujaratis in an unsuccessful attempt in 1538 to take the town of Diu from the Portuguese.
