Purnea has a rich Hindu history and a glorious past.During Mughal rule Purnea was an outlying military province, its revenue was mostly spent on protecting its borders against tribes from the north and east. Its local governor raised a rebellion against Siraj ud-Daulah in 1757, after the capture of Calcutta. In 1765, along with the rest of Bengal, the district became a British possession. Purnea is famous for its uniquely designed Ramakrishna Mission where Durga Puja in the month of April is celebrated with due devotion and honour. Purnea is also famous for the oldest temple of Mata Puran Devi, which is hardly 5 km away from the main city. There is a theory that Purnia got its name from that temple. Some people believe that many years ago Purnea was Purna–Aranya which stands for “complete jungle”, and that’s why it has got the name Purnea.
