Sukhothai dynasty

Naresuan (1555/1556 – 25 April 1605), commonly known as Naresuan the Great, or Sanphet II was the 18th monarch of the Ayutthaya Kingdom and the 2nd of the Sukhothai dynasty. He was the king of the Ayutthaya Kingdom from 1590 and overlord of Lan Na from 1602 until his death in 1605. Naresuan is one of Thailand's most revered monarchs as he is known for his campaigns to free Ayutthaya from the vassalage of the First Toungoo Empire. During his reign, numerous wars were fought against Taungoo Burma. Naresuan also welcomed the Dutch.

Ekathotsarot (, , ) or Sanphet III (); 1560 – 1610/11) was the King of Ayutthaya from 1605 to 1610/11 and overlord of Lan Na from 1605 to 1608/09, succeeding his brother Naresuan. His reign was mostly peaceful as Siam was a powerful state through the conquests of Naresuan. It was also during his reign that foreigners of various origin began to fill the mercenary corps. In particular, the king had a regiment of professional Japanese guards under the command of Yamada Nagamasa.

King Songtham () also known as King Borommaracha I () was the king of the Ayutthaya Kingdom from 1611 to 1628, of the Sukhothai dynasty.

It also saw the beginning of expanded overseas trade, particularly with the Dutch and the Japanese. Songtham employed foreign mercenaries as royal guards; most notably the Japanese soldier Yamada Nagamasa (Okya Senaphimuk), commander of the Japanese volunteer corps.
