Mahinthrathirat was king of Ayutthaya 1564 to 1568 and again in 1569. He ruled his first reign as a vassal of Toungoo Burma before restoring his father in 1568 as the sovereign king. He became king again in 1569 after his father's death during the Third Siege of Ayutthaya by Toungoo forces. Mahinthrathirat was the last monarch of the Suphannaphum Dynasty as the kingdom fell to the Burmese in 1569. Mahinthrathirat was known for his efforts to counter Burmese and Phitsanulok power by seeking alliance with Setthathirath of Lan Xang.

The Ayutthaya Kingdom or the Empire of Ayutthaya was a Mon and later Siamese kingdom that existed in Southeast Asia from 1351 to 1767, centered around the city of Ayutthaya, in Siam, or present-day Thailand. European travellers in the early 16th century called Ayutthaya one of the three great powers of Asia. The Ayutthaya Kingdom is considered to be the precursor of modern Thailand, and its developments are an important part of the history of Thailand.
