Kavad II vs Ramesses X

Kavad II, then known as Sheroe, led a coup against his father Khosrow II, imprisoning and later executing him. This act ended Khosrow's long reign and the Sasanian-Byzantine war, but plunged the empire into civil war and decline.

Kavad II ordered the execution of 17 of his brothers to eliminate potential rivals to the throne. This massacre decimated the Sasanian royal family and weakened the dynasty's legitimacy, contributing to the empire's instability.

Kavad II negotiated a peace treaty with the Byzantine Empire, ending the decades-long war. The treaty restored pre-war borders and returned the True Cross to Jerusalem, but the Sasanian Empire was left exhausted and weakened.

Ramesses X began construction of his tomb in the Valley of the Kings, designated KV18. The tomb was left unfinished and never used for burial, reflecting the instability and reduced resources of his reign.

During Ramesses X's brief reign, Egypt lost effective control over Nubia, a key source of gold and resources. The withdrawal of Egyptian garrisons and administrative presence allowed local Nubian leaders to assert independence, weakening Egypt's southern frontier.

During Ramesses X's reign, the royal tomb workers at Deir el-Medina went on strike due to delayed wages and food supplies. This labor action, recorded in ostraca, highlighted the economic decline and administrative failures of the late New Kingdom.
