Civil War Wiki

Marcus[1] H. MacWillie[2] was a politician who represented the Confederate Arizona Territory in the Congress of the Confederate States during the American Civil War.

Little is known of MacWillie's birthplace, date of birth, or his early life. MacWillie passed his bar exam and established a legal practice in Texas. He later moved to La Mesilla in what is now New Mexico and resumed his legal career.[3]

Following the outbreak of the Civil War, MacWillie became the Attorney General of the Confederate-claimed Arizona Territory in the newly designated capital of La Mesilla.[4] Through the shrewd political efforts of his powerful friend John R. Baylor, MacWillie was selected in early 1862 to replace Baylor's rival Granville Henderson Oury as the territory's representative to the permanent Congress.[5] Despite Arizona and New Mexico being taken over by the Union Army later in 1862, MacWillie continued to represent the territory throughout the First Confederate Congress (March 11, 1862 – February 17, 1864). He then served in the Second Confederate Congress until the end of the war.[6]

MacWillie's activities following the war are uncertain, as is his date and place of death or his burial location.
