The origin of the name Katihar is shrouded in mystery and is the subject of much debate among historians and linguists. Some theories suggest that the name is derived from the Sanskrit word “Kathivara,” which means “wooden door,” while others believe that it is derived from the name of a local tribe called “Kathi.” Another theory suggests that the name is a corruption of the words “Kashi” and “Har,” referring to the city’s association with the holy city of Varanasi and the Hindu god Shiva, who is also known as “Har.” Despite the various theories, the exact origin of the name Katihar remains unknown, and it continues to be a subject of fascination for locals and visitors alike.
