During the Viceroyalty of Lord Curzon, several significant events took place. First, the establishment of the Department of Archaeology was an important step towards preserving India`s rich historical heritage. This department worked towards the study and preservation of ancient monuments and archaeological sites.
Second, the Second Delhi Durbar was held during Lord Curzon`s tenure. This grand and extravagant event was organized to commemorate the coronation of King Edward VII as the Emperor of India. It was a display of pomp and power, showcasing the might of the British Empire.
Third, the partition of Bengal took place under Lord Curzon`s administration. This controversial decision aimed to divide Bengal along religious lines, which led to widespread protests and political unrest in the region.
However, the formation of the Indian National Congress did not occur during Lord Curzon`s viceroyalty. The Indian National Congress was established in 1885, during the viceroyalty of Lord Dufferin.
