Bengal Subah in the context of "Azim-ush-Shan"

The British Empire comprised the dominions, colonies, protectorates, mandates, and other territories ruled or administered by the United Kingdom and its predecessor states. It began with the overseas possessions and trading posts established by England in the late 16th and early 17th centuries, and colonisation attempts by Scotland during the 17th century. At its height in the 19th and early 20th centuries, it became the largest empire in history and, for a century, was the foremost global power. By 1913, the British Empire held sway over 412 million people, 23 percent of the world population at the time, and by 1920, it covered 35.5 million km (13.7 million sq mi), 24 per cent of the Earth's total land area. As a result, its constitutional, legal, linguistic, and cultural legacy is widespread. At the peak of its power, it was described as "the empire on which the sun never sets", as the sun was always shining on at least one of its territories.

During the Age of Discovery in the 15th and 16th centuries, Portugal and Spain pioneered European exploration of the world, and in the process established large overseas empires. Motivated by the great wealth these empires generated, England, France, and the Netherlands began to establish colonies and trade networks of their own in the Americas and Asia. A series of wars in the 17th and 18th centuries with the Netherlands and France left Britain the dominant colonial power in North America. Britain became a major power in the Indian subcontinent after the East India Company's conquest of Mughal Bengal at the Battle of Plassey in 1757.

The Battle of Plassey was a decisive victory of the British East India Company, under the leadership of Robert Clive, over the Nawab of Bengal and his French allies on 23 June 1757. The victory was made possible by the defection of Mir Jafar, Nawab Siraj-ud-Daulah's commander in chief, as well as much of the Bengal Subah's armies being earlier committed against an Afghan invasion led by Ahmad Shah Durrani against the Mughal Empire. The battle helped the British East India Company take complete control of Bengal in 1773. Over the next hundred years, they continued to expand their control over vast territories in the rest of the Indian subcontinent and Burma.

The battle took place at Palashi (Anglicised version: Plassey) on the banks of the Hooghly River, about 150 kilometres (93 mi) north of Calcutta (now Kolkata) and south of Murshidabad in West Bengal, then capital of Bengal State. The belligerents were the British East India Company, and the Nawab Siraj-ud-Daulah, the last independent Nawab of Bengal. He succeeded Alivardi Khan (his maternal grandfather). Siraj-ud-Daulah had become the Nawab of Bengal the year before, and he had ordered the English to stop the extension of their fortification. Robert Clive bribed Mir Jafar, the commander-in-chief of the Nawab's army, and also promised to make him Nawab of Bengal. Clive defeated Siraj-ud-Daulah at Plassey in 1757 and captured Calcutta.

Bangladesh, officially the People's Republic of Bangladesh, is a country in South Asia. It is the eighth-most populous country in the world and among the most densely populated with a population of over 171 million within an area of 148,460 square kilometres (57,320 sq mi). Bangladesh shares land borders with India to the north, west, and east, and Myanmar to the southeast. It has a coastline along the Bay of Bengal to its south and is separated from Bhutan and Nepal by the Siliguri Corridor, and from China by the Indian state of Sikkim to its north. Dhaka, the capital and largest city, is the nation's political, financial, and cultural centre. Chittagong is the second-largest city and the busiest port of the country.

The territory of modern Bangladesh was a stronghold of many Hindu and Buddhist dynasties in ancient history. Following the Muslim conquest in 1204, the region saw Sultanate and Mughal rule. During the Mughal period, particularly under the Bengal Subah, the region emerged as one of the most prosperous and commercially active parts of the world, known for its thriving textile industry and agricultural productivity. The Battle of Plassey in 1757 marked the beginning of British colonial rule for the following two centuries. In the aftermath of the Partition of India in 1947, East Bengal became the eastern and most populous wing of the newly formed Dominion of Pakistan and was later renamed to East Pakistan.

Bengal (/bɛnˈɡɔːl/ ben-GAWL) is a geographical, ethnolinguistic, historically geopolitical region in South Asia, located north of the Bay of Bengal. Today, it is politically divided between the sovereign state of Bangladesh, the Indian state of West Bengal, and Karimganj district in the Indian state of Assam.

The ancient Vanga Kingdom is widely regarded as the namesake of the Bengal region. The Bengali calendar dates back to the reign of Shashanka in the 7th century CE. The Pala Empire was founded in Bengal during the 8th century. The Sena dynasty and Deva dynasty ruled between the 11th and 13th centuries. By the 14th century, Bengal was absorbed by Muslim conquests in the Indian subcontinent. An independent Bengal Sultanate was formed and became the eastern frontier of the Islamic world. During this period, Bengal's rule and influence spread to Assam, Arakan, Tripura, Bihar, and Odisha (formerly- Orissa). Bengal Subah later emerged as a prosperous part of the Mughal Empire.

The Bihar Subah (Persian: صوبه بهار) was a province (suba) of the Mughal Empire that was formed in 1575. It was one of the original twelve subas established by Emperor Akbar. Its seat was in the city of Patna which was also known as Azimabad. The seat of Azimabad was named after the Mughal prince, Azim-ush-Shan who was the son of Emperor Shah Alam I.

The suba was bordered to the west by the subas of Illahabad and Awadh and to the east by Bengal Subah.

The Nawabs of Bengal were the Independent hereditary rulers of Bengal. In the early 18th-century, the Nawab of Bengal was the independent ruler of Bengal (Bengal, Bihar and Orissa which constitute the modern-day Indian states of West Bengal, Bihar and Odisha and the sovereign country of Bangladesh). The Bengal Subah reached its peak during the reign of Nawab Shuja-ud-Din Muhammad Khan. They are often referred to as the Nawab of Bengal, Bihar and Orissa (Bengali: বাংলা, বিহার ও উড়িষ্যার নবাব). The Nawabi Bengal's capital were based in Murshidabad which was centrally located within Bengal, Bihar, and Odisha. Their chief, a former prime minister, became the first Nawab. The Nawabs governed as independent monarchs. The Nawabs, backed by bankers such as the Jagat Seth, became the financial backbone of the Subcontinent court.

The Nawabs, especially under the rule of Alivardi Khan of 16 years, were heavily engaged in various wars against the Marathas. Towards the end, he turned his attention to rebuilding and restoring Bengal.

Murshidabad (Bengali pronunciation: [murʃidabad]), is a town in the Indian state of West Bengal. This town is the headquarters of Lalbag subdivision of Murshidabad district. It is located on the eastern bank of the Bhagirathi River. During the 18th century, Murshidabad was a prosperous and cosmopolitan town. Murshidabad was the capital of the Bengal Subah for seventy years. This town was the home of wealthy banking and merchant families from different parts of the Indian subcontinent and wider Eurasia. European companies, including the British East India Company, the French East India Company, the Dutch East India Company and the Danish East India Company, conducted business and operated factories around the city. The town was also a centre of art and culture.

The city's decline began with the defeat of the last independent Nawab of Bengal Siraj-ud-Daulah at the Battle of Plassey in 1757. The Nawab was demoted to the status of a zamindar known as the Nawab of Murshidabad. The British shifted the treasury, courts and revenue office to Calcutta. In the 19th century, the population was estimated to be 46,000. Murshidabad became a district headquarters of the Bengal Presidency. It was declared as a municipality in 1869.
