The Hittite empire suffered serious losses of territory during Tudhaliya's reign, with even the capital itself being burnt down. But, under the able guidance of Tudhaliya's son, the future Suppiluliuma I, the Hittites began to make a recovery while Tudhaliya reigned.
The proper numbering of the Hittite rulers who bore the name Tudhaliya is problematic. There was a Hattian era figure who bore the name Tudhaliya who may or may not have ruled as king. Other reconstructions insert a Tudhaliya directly after Muwatalli I, but before the more famous ruler frequently credited with founding the Empire. The Tudhaliya discussed in this article will be generally found as either "the second" or "the third".
