Patna, the capital, was once the ancient city of Pataliputra, a center of power in ancient India. Despite its historical significance, Bihar faces challenges like poverty and underdevelopment, but it's also seeing growth in agriculture, manufacturing, and education. The state's strategic location has made it a crossroads for trade and culture.
