Suppiluliuma II was a king of the Hittite Empire, ruling during the late 13th century BCE. He is often considered the last significant ruler of the Hittites, a civilization known for its advanced culture and military prowess. His reign marked a period of decline for the empire, which faced invasions and internal strife. During his rule, Suppiluliuma II attempted to restore the Hittite Empire's former glory by engaging in military campaigns and diplomatic efforts. However, his efforts were ultimately unsuccessful, and the empire fell into decline, leading to its eventual collapse in the following centuries.
