Bakhtiyar Khalji in the context of Bakhtiyar Khalji's Tibet campaign

Gauḍa (also known as Gaur, Gour, Lakhnauti, Lakshmanavati and Jannatabad) is a historic city of Bengal in the eastern part of the Indian subcontinent, and one of the most prominent capitals of classical and medieval India, being the capital city of Bengal under several kingdoms. The Gauḍa region was also a province of several pan-Indian empires. During the seventh century, the Gauda Kingdom was founded by King Shashanka, whose reign corresponds with the beginning of the Bengali calendar. Gour gradually became synonymous with Bengal and Bengalis. It was conquered by Bakhtiyar Khalji, a lieutenant of the Ghurid ruler Muhammad of Ghori in 1203.

For a period of 112 years, between 1453 and 1565, Gauda was the capital of the Bengal Sultanate. In 1500, Gauda was the fifth-most populous city in the world, with a population of 200,000, as well as one of the most densely populated cities in the Indian subcontinent. The Portuguese left detailed accounts of the city. The Sultans built a citadel, many mosques, a royal palace, canals and bridges. Buildings featured glazed tiles.

The history of Bangladesh dates back over four millennia to the Chalcolithic period. The region's early history was characterized by a succession of Hindu and Buddhist kingdoms and empires that fought for control over the Bengal region. Islam arrived in the 8th century and gradually became dominant from the early 13th century with conquests led by Bakhtiyar Khalji and the activities of Sunni missionaries like Shah Jalal. Muslim rulers promoted the spread of Islam by building mosques across the region. From the 14th century onward, Bengal was ruled by the Bengal Sultanate, founded by Fakhruddin Mubarak Shah, who established an individual currency. The Bengal Sultanate expanded under rulers like Shamsuddin Ilyas Shah, leading to economic prosperity and military dominance, with Bengal being referred to by Europeans as the richest country to trade with. The region later became a part of the Mughal Empire, and according to historian C. A. Bayly, it was probably the empire's wealthiest province.

Following the decline of the Mughal Empire in the early 1700s, Bengal became a semi-independent state under the Nawabs of Bengal, ultimately led by Siraj ud-Daulah. It was later conquered by the British East India Company after the Battle of Plassey in 1757. Bengal played a crucial role in the Industrial Revolution in Britain, but also faced significant deindustrialization. The Bengal Presidency was established during British rule.
