In the earlier period,
Mithila was full of industrial estates. There were many industries in the region in regime of
Darbhanga Raj Kingdom. These industries were flourishing the economy of the region. After the
independence of India, the rule of
Darbhanga Raj Kingdom ended and then the industrial estates of the region started gradually closing due to the negligence of the central government as well as state government of
Bihar. The region was full of many sugar mills, cotton mills, paper industries, chocolate factories and many more agricultural industries. In the last three decades, due to the castism politics in
Bihar by the leaders there, the agenda of industrial development got neglected and gradually industries got closed. Nowadays these industrial estates have become ruins. This led to the migrations of labours and human resources from the area to the
metropolitan cities of the country. The sugar mills of
Sakari, Lohat, Raiyam and
Samastipur was very famous in the country.
Mithila was the bowl of sugar in India three decades ago.
Hayaghat was famous for Ashok Paper Industry and similarly
Pandaul was famous for Cotton mills. Purnea, Saharsa, Katihar, Muzaffarpur and, Darbhanga was famous for Jute industries since 1794 up to 1990. == Tourism in Mithila ==
