Background:
The Burma War was a significant historical event that took place during the British colonial rule in India. Understanding the role of the Viceroys in this conflict is crucial to grasp the context of the question.

Dalhousie:
Lord Dalhousie was the Governor-General of India from 1848 to 1856. During his tenure, he played a pivotal role in the Second Anglo-Burmese War (1852). The war resulted in the British annexation of Lower Burma, marking a significant expansion of British territories in the region.

Dufferin:
Lord Dufferin served as the Viceroy of India from 1884 to 1888. Although he was not directly involved in the Burma War, his term witnessed the aftermath and consequences of British colonial policies in the region, including the administration of the newly acquired territories.

Dalhousie and Dufferin both:
Both Lord Dalhousie and Lord Dufferin had a connection to the Burma War, albeit in different capacities. Dalhousie's direct involvement in the conflict as the Governor-General underscored his role in expanding British influence in Burma. On the other hand, Dufferin's term as Viceroy overlapped with the aftermath of the war, highlighting the continuity of British policies in the region.

Conclusion:
In conclusion, both Lord Dalhousie and Lord Dufferin are related to the Burma War in different ways. Dalhousie's direct role in the conflict and Dufferin's indirect association with the consequences of the war illustrate the enduring impact of colonial expansionism on the Indian subcontinent.
