During the mid-18th century, India was going through a turbulent time marked by the fall of the Mughal Empire and the rise of regional rulers. At the same time, the British East India Company was gaining ground—not just through trade but also through increasing military involvement. Although Mir Qasim, the Nawab of Bengal, initially supported the British, he turned against them due to unfair trade practices and later allied with Shuja-ud-Daula and the Mughal Emperor Shah Alam II. The British, having already taken control of Bengal after the Battle of Plassey in 1757, were looking to expand further, which led to the conflict at Buxar. Many believe it was this battle—not Plassey—that solidified British dominance in India.
Secrets of the Battle of Buxar:
Each participating party in the Battle of Buxar had its inspirations. The English East India Company, driven by Major Hector Munro, planned to tighten its grip on Bengal and gain income privileges over different domains. On the opposite side, Mir Qasim needed to recover Bengal, Shuja-ud-Daula meant to safeguard Oudh, and Shah Alam II looked to reestablish the respect of the Mughal Empire.
| Participants | Respective Roles |
| Mir Qasim | The English terms “Dastak” and “Farmans” offended him. He plotted against the Mughal Emperor Shah Alam II and the Nawab of Awadh by forming an alliance. |
| Shuja-ud-Daulah | He was Awadh’s Nawab. Along with Mir Qasim and Shah Alam II, he established a confederacy. |
| Shah Alam II | The Mughal Emperor was he. His goal was to expel the English from Bengal. |
| Hector Munro | He was a British Army major. He led the English side in the Buxar War. |
| Robert Clive | After winning the Buxar War, he made treaties with Shah Alam II and Shuja-Ud-Daulah. |

The Battle of Buxar was a clash between two opposing forces: the British East India Company and a coalition of Indian rulers. This coalition consisted of Mir Qasim, the Nawab of Bengal; Shuja-ud-Daula, the Nawab of Oudh; and Shah Alam II, the Mughal Emperor.
On the British side, the key leader was Major Hector Munro, a great military commander. He was in charge of the British East India Company’s forces and was known for his tactical brilliance. For the Indian coalition, Mir Qasim Shuja-ud-Daula and Shah Alam II were the principal leaders.
The English had a thoroughly prepared armed force, having unrivalled big guns and restrained troops. Their technique was to utilize their cannons effectively and keep a tight formation to counter the mush but less coordinated Indian powers. The Indian alliance, then again, had a bigger armed force; however, it came up short on discipline and high-level weapons that the English had. Their system was to overpower the English with numbers and utilize their insight into the neighbourhood landscape for their potential benefit.
The battle took place on October 22, 1764. The war’s geographical location is in present-day Bihar, India. The battle of Buxar’s date and its location are significant because the area provided a strategic advantage to the British, allowing them to utilize their artillery effectively.
The Battle of Buxar was a complex military engagement with multiple participants, each with their leader’s strengths and strategies. The British East India Company emerged victorious largely due to their superior military tactics and discipline, forever altering the course of Indian history.
