Gladstone was an intense opponent of the opium trade. Referring to the opium trade between British India and Qing China, Gladstone described it as "infamous and atrocious". Gladstone emerged as a fierce critic of the Opium Wars, which Britain waged to re-legalise the British opium trade into China, which had been made illegal by the Chinese government. He publicly lambasted the wars as "Palmerston's Opium War" and said that he felt "in dread of the judgements of God upon England for our national iniquity towards China" in May 1840. A famous speech was made by Gladstone in Parliament against the First Opium War. Gladstone criticised it as "a war more unjust in its origin, a war more calculated in its progress to cover this country with permanent disgrace". His hostility to opium stemmed from the effects of opium upon his sister Helen. Before 1841, Gladstone was reluctant to join the Peel government because of the First Opium War, which Palmerston had brought on.
