Bengal SultanateThe Bengal Sultanate (Middle Bengali: শাহী বাঙ্গালা Shahī Baṅgala, Classical Persian: Saltanat-e-Bangālah) was a Sunni Muslim empire 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 in the subcontinent, including parts of Odisha in the southwest, Arakan in the southeast, and Tripura in the east.
Bengali language movementThe Bengali language movement (Bhasha Andolôn) was a political movement in former East Bengal (renamed East Pakistan in 1952) advocating the recognition of the Bengali language as an official language of the then-Dominion of Pakistan to allow its use in government affairs, the continuation of its use as a medium of education, its use in media, currency and stamps, and to maintain its writing in the Bengali script.
Mughal EmpireThe Mughal Empire was an early modern empire based in South Asia between the 16th and 19th centuries. For some two hundred years, the empire stretched from the outer fringes of the Indus River Basin in the west, northern Afghanistan in the northwest, and Kashmir in the north, to the highlands of present-day Assam and Bangladesh in the east, and the uplands of the Deccan Plateau in South India.
Delhi SultanateThe Delhi Sultanate, or the Sultanate of Delhi, was a Muslim empire based in Delhi that stretched over large parts of the Indian subcontinent during the period of Medieval India, for 320 years (1206–1526). Following the invasion of South Asia by the Ghurid dynasty, five largely unrelated dynasties ruled over the Delhi Sultanate sequentially: the Mamluk dynasty (1206–1290), the Khalji dynasty (1290–1320), the Tughlaq dynasty (1320–1414), the Sayyid dynasty (1414–1451), and the Lodi dynasty (1451–1526).
