Most of Bengal is in the enormous delta area formed by a complex of three rivers. The Ganges flows roughly west-to-east across much of northern India, and is historically the country's most important river. The Brahmaputra is the greatest river of northeast India, and both it and the Meghna are important in Bangladesh. By the time they reach the sea, the combined rivers (called the Padma in this region) are the world's third largest by volume of water discharged. The Brahmaputra, considered by itself, ranks eighth. At times political units called "Bengal" extended into nearby areas which were not ethnically or linguistically Bengali. When the British defeated the last Nawab of Bengal and his French allies at the Battle of Plassey in 1757, they took not only Bengal itself but also the Nawab's other territories, now the states of Bihar, Odisha and Jharkhand. Under the British, what is now Assam was administered as part of the Bengal Presidency.
