Shishunaga had transferred the capital of Magadha to Vaishali. Kalashoka succeeded his father Shishunaga. Kalashoka again transferred the capital to Pataliputra. According to Buddhist literature, the Second Buddhist Council, held 100 years after the Maha Parinirvana of Lord Buddha, in Vaishali, was patronised by King Kalashoka. But despite King Kalashoka's best efforts, differences among the Buddhists persisted. He divided his kingdom between his ten sons, who ruled simultaneously.
