Post-presidency
Upon leaving the White House in 1913, Taft was appointed the Chancellor Kent Professor of Law and Legal History at Yale Law School. While at Yale, Taft was initiated as an honorary member of the Acacia Fraternity. At the same time, Taft was elected president of the American Bar Association. He spent much of his time writing newspaper articles and books, most notably his series on American legal philosophy. He was a vigorous opponent of prohibition in the United States, predicting the undesirable situation that the Eighteenth Amendment and prohibition would create. He also continued to advocate world peace through international arbitration, urging nations to enter into arbitration treaties with each other and promoting the idea of a League of Nations even before the First World War began. Taft was elected a Fellow of the American Academy of Arts and Sciences in 1914.
When World War I did break out in Europe in 1914, however, Taft founded the League to Enforce Peace. He was a co-chairman of the powerful National War Labor Board between 1917 and 1918. Although he continually advocated peace, he strongly favored conscription once the United States entered the War, pleading publicly that the United States not fight a "finicky" war. He feared the war would be long, but was for fighting it out to a finish, given what he viewed as "Germany's brutality."
