After Ḫattušili III as King wrote up a treaty with "Ulmi-Tessup" which confirmed Kurunta's rule over Tarḫuntašša, Ḫattušili elevated Tudḫaliya over his older brother to be his crown prince. Tudḫaliya as king drew up a bronze tablet treaty confirming the links between him and Kurunta.
Tudḫaliya had a sister, Maathorneferure, who served as Great Royal Wife to Pharaoh Ramesses II of Egypt.

Tudḫaliya IV responded by building at least 13 dams to secure water supplies, one of which still survives to this day at Alacahöyük.https://archive.today/20070812073240/http://www.thenewanatolian.com/tna-15106.html
