Lord Ellenborough was the Governor-General of India at the time of the Annexation of Sindh in 1843.

Background:
Sindh, located in present-day Pakistan, was a region ruled by various dynasties and empires throughout history. By the early 19th century, it came under the control of the Talpur Mirs, who established their rule in the region. However, the British East India Company had a growing interest in expanding its influence in the Indian subcontinent, and Sindh was seen as a strategic location due to its proximity to the Arabian Sea.

Events leading to the Annexation of Sindh:
- In 1838, an agreement was signed between the British and the Talpur Mirs, allowing the British to have commercial and military access to Sindh.
- However, by 1841, the British had become dissatisfied with the Talpur Mirs' administration and their alleged support to anti-British factions in the region.
- In 1842, Charles Napier was appointed as the British Resident in Sindh, with the intent to bring Sindh under British control.
- Napier engaged in a series of military campaigns, defeating the Talpur Mirs in the Battle of Miani and the Battle of Hyderabad in 1843.

Lord Ellenborough's Role:
Lord Ellenborough, as the Governor-General of India, was responsible for overseeing British policies and actions in the Indian subcontinent. He played a significant role in the Annexation of Sindh:
- Ellenborough supported Charles Napier's military campaigns in Sindh and approved his actions.
- He saw the annexation of Sindh as a means to secure British interests in the region, particularly in relation to trade and access to the Arabian Sea.
- Lord Ellenborough issued a proclamation in 1843, declaring the annexation of Sindh by the British East India Company.

Significance of the Annexation:
The annexation of Sindh by the British East India Company had several implications:
- It expanded British territorial control in the Indian subcontinent.
- It provided the British with a strategic location for their naval and commercial activities.
- The annexation of Sindh marked a significant step in the British colonization of the Indian subcontinent, as it further weakened indigenous rulers and paved the way for British dominance.
