This study examines the five American Legion battalions of the Canadian Expeditionary Force formed in 1915 specifically to recruit American volunteers for the Canadian overseas contingent of the First World War. This study reviews the organization of Canada's militia and Anglo-American relations before examining the formation of the American Legion, the background of its men, and the diplomatic repercussions it sparked. This study is based largely on material in the Public Archives of Canada including war records and the personal papers of several participants. During its brief existence, the American Legion precipitated constitutional, diplomatic, and political problems. The issues the American Legion raised were mostly solved by America's entry in the war. The episode hastened the maturity of Canada as a nation.

John Hancock was a Texas Unionist. After the Civil War, he became an opponent of the Radical Republicans. He was elected to Congress in 1871 and had some success working on issues important to Texas. As the state was redeemed from Radical Republican rule, Hancock was increasingly attacked for his Unionism. This led to a tough fight for renomination in 1874, and losses in races for the U.S. Senate and renomination in 1876. He was an unsuccessful congressional candidate in 1878, but was elected again in 1882. By then his political influence had waned and he did not seek renomination in 1884. Hancock had the potential to be a major political leader, but lingering resentment to his Unionism hampered his political career.
