Before the 17th century, navigation on the Ganga was limited to local transport between fragmented kingdoms. In the mid-16th century, Akbar brought his army to Bengal by boat. The golden age of navigation was in the mid-19th century when steamboat companies plied as far as Garhmukteshwar. However, soon after, the expansion of railways and construction of canals reduced cargo traffic on the river. Navigation was further impacted by the Upper Ganga Canal diverting water. In 1986, the Inland Waterways Authority was established to develop navigation along the Ganga from Haldia to Allahabad as National Waterway No. 1.
