Shuja-ud-Din Muhammad Khan in the context of Murshid Quli Khan

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.

Sarfarāz Khān (c. 1700 – 29 April 1740), born Mīrza Asadullāh, was a Nawab of Bengal(Independent). Sarfaraz Khan's maternal grandfather, Nawab Murshid Quli Khan of Bengal (Bengal, Bihar and Orissa) nominated him as the direct heir to him as there was no direct heir. After Murshid Quli's death in 1727, Sarfaraz ascended to the Masnad (throne) of the Nawab. Sarfaraz's father, Shuja-ud-Din Muhammad Khan, then the Subahdar of Orissa, getting to know it arrived at Murshidabad, the capital of the Nawabs of Bengal with a huge army. To avoid a conflict in the family the dowager Begum of the Nawab asked Shuja-ud-Din to ascend to the Masnad after Sarfaraz abdicated in favour of his father. However, circumstances led Shuja-ud-Din to nominate Sarfaraz as his heir and after Shuja-us-Din's death in 1739, Sarfaraz Khan again ascended to the Masnad as the Nawab of Bengal (Bengal, Bihar and Orissa).
