The Mughals in their heyday had a profound and lasting effect on Bengal. When Akbar ascended the throne at Delhi, a road connecting Bengal with Delhi was under construction and a postal service was being planned as a step toward drawing Bengal into the operations of the empire. Akbar implemented the present-day Bengali calendar, and his son, Jahangir (1605-27), introduced civil and military officials from outside Bengal who received rights to collect taxes on land.
