Lady Canning was in the country during the India Mutiny, a rebellion in India against the rule of the British East India Company that ran from May 1857 to July 1859. Her husband was much criticized for his perceived clemency of the rebels, but the Cannings had the firm support of Victoria. After the end of the Mutiny, rule of India was transferred over to the British Crown. Lord Canning was made its viceroy, making his wife the country's first vicereine. Her new position lacked official duties, but she did play a social role and partook in philanthropic efforts.
