<em> The Sultanate of Bengal (Bengali: শাহী বাংলা, Persian: شاهی بنگاله Shāhī Bangālah), also known as the Bengal Sultanate or simply Bengal (Persian: بنگاله Bangālah, Bengali: বাংলা, romanized: Bangla),[2] was an empire[3][4][5] based in Bengal for much of the 14th, 15th and 16th centuries. It was the dominant power of the Ganges–Brahmaputra Delta, with a network of mint towns spread across the region. The Bengal Sultanate had a circle of vassal states, including Odisha in the southwest, Arakan in the southeast,[6] and Tripura in the east.[7] In the early 16th-century, the Bengal Sultanate reached the peak of its territorial growth with control over Kamrup and Kamata in the northeast and Jaunpur and Bihar in the west. It was reputed as a thriving trading nation and one of Asia's strongest states. Its decline began with an interregnum by the Suri Empire, followed by Mughal conquest and disintegration into petty kingdoms.</em>
