Peel often started from a traditional Tory position in opposition to a measure, then reversed his stance and became the leader in supporting liberal legislation. This happened with the Test Act, Catholic Emancipation, the Reform Act, income tax and, most notably, the repeal of the Corn Laws as the first two years of the Irish famine forced this resolution because of the urgent need for new food supplies. Peel, a Conservative, achieved repeal with the support of the Whigs in Parliament, overcoming the opposition of most of his own party. Many critics accordingly saw him as a traitor to the Tory cause, or as "a Liberal wolf in sheep's clothing", because his final position reflected liberal ideas. Historian A.J.P. Taylor says: "Peel was in the first rank of 19th century statesmen. He carried Catholic Emancipation; he repealed the Corn Laws; he created the modern Conservative Party on the ruins of the old Toryism."
