Bimbisara vs Kavad II Sheroe

Bimbisara married Chellana, daughter of the Licchavi chief Chetaka of Vaishali. This marriage alliance strengthened Magadha's ties with the powerful Licchavi republic and produced his son Ajatashatru.

Bimbisara annexed the kingdom of Anga (modern Bihar) to the Magadha empire. This conquest gave Magadha control over the Ganges river trade route and access to the sea, strengthening its economic and military power.

Bimbisara met Gautama Buddha and became a lay follower, donating the Veluvana Bamboo Grove monastery near Rajagriha. This patronage helped establish Buddhism in Magadha and provided the Buddha with a permanent residence during the rainy season.

Bimbisara was imprisoned by his son Ajatashatru, who seized the throne. According to Buddhist sources, Bimbisara died in captivity, possibly by starvation or suicide. This event marked a violent succession in Magadha.

Kavad II, then known as Sheroe, led a coup against his father Khosrow II, imprisoning and executing him. This ended Khosrow's long reign and the Sasanian war with Byzantium.

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

Kavad II negotiated a peace treaty with the Byzantine Empire, ending the decades-long Sasanian-Byzantine war. He returned all conquered territories, including Egypt and the Levant, to Byzantine control.

Kavad II died of plague after a reign of only a few months. His death plunged the Sasanian Empire into further chaos and civil war.
