Orai, Jalaun was the scene of much violence during the Revolt of 1857. When the news of the rising at Kanpur reached Kalpi, the men of the 53rd Native Infantry deserted their officers, and in June the Jhansi rebels reached the district, and began their murder of Europeans. It was not until September 1858 that the rebels were finally defeated. In the later 19th century, the district suffered much from the invasive kans grass (Saccharumspontaneum), owing to the spread of which many villages were abandoned and their land thrown out of cultivation. The population of the district was 399,726 in 1901, and the two largest towns are Konch and Kalpi (pop. 10,139 in 1901). The district was traversed by the line of the Indian Midland railway from Jhansi to Kanpur. A small part of it is watered by the Bethwa Canal. Grain, oil-seeds, cotton and ghee were exported.
