State flag of Pennsylvania, c. 1863

The 91st Pennsylvania Volunteer Infantry was a Union infantry regiment which fought in multiple key engagements of the American Civil War, including the Battle of Fredericksburg, Battle of Chancellorsville and Battle of Gettysburg. It was established through the combined efforts of Edgar M. Gregory, who had received approval from the U.S. War Department to begin recruiting soldiers for an entirely new regiment during the fall of 1861, and Edward E. Wallace, who had initiated his own recruitment efforts that October. Their recruits were volunteers, the majority of whom initially enlisted for three-year terms of service from their hometown of Philadelphia; they were divided into 10 lettered companies upon muster in during early December 1861: A, B, C, D, E, F, G, H, I, and K. (In later years, as the war dragged on and the need for reinforcements arose, additional men were drafted from communities across the state.)

The men who enrolled with the 91st Pennsylvania wore modified Zouave uniforms (dark blue Zouave-style jacket and vest with yellow trim, sky blue sash, sky blue pantaloons, and red fez with blue tassel). The regiment's leaders were presented with the unit's First State Color on December 6, a flag which had been manufactured by Horstmann Brothers and Company. (Full article...)

Indiana, a state in the Midwest, played an important role in supporting the Union during the American Civil War. Despite anti-war activity within the state, and southern Indiana's ancestral ties to the South, Indiana was a strong supporter of the Union. Indiana contributed approximately 210,000 Union soldiers, sailors, and marines. Indiana's soldiers served in 308 military engagements during the war; the majority of them in the western theater, between the Mississippi River and the Appalachian Mountains. Indiana's war-related deaths reached 25,028 (7,243 from battle and 17,785 from disease). Its state government provided funds to purchase equipment, food, and supplies for troops in the field. Indiana, an agriculturally rich state containing the fifth-highest population in the Union, was critical to the North's success due to its geographical location, large population, and agricultural production. Indiana residents, also known as Hoosiers, supplied the Union with manpower for the war effort, a railroad network and access to the Ohio River and the Great Lakes, and agricultural products such as grain and livestock. The state experienced two minor raids by Confederate forces, and one major raid in 1863, which caused a brief panic in southern portions of the state and its capital city, Indianapolis.

Indiana experienced significant political strife during the war, especially after Governor Oliver P. Morton suppressed the Democratic-controlled state legislature, which had an anti-war (Copperhead) element. Major debates related to the issues of slavery and emancipation, military service for African Americans, and the draft, ensued. These led to violence. In 1863, after the state legislature failed to pass a budget and left the state without the authority to collect taxes, Governor Morton acted outside his state's constitutional authority to secure funding through federal and private loans to operate the state government and avert a financial crisis.

Jefferson F. Davis (June 3, 1808 – December 6, 1889) was an American politician who served as the first and only president of the Confederate States from 1861 to 1865. He represented Mississippi in the United States Senate and the House of Representatives as a member of the Democratic Party before the American Civil War. He was the United States Secretary of War from 1853 to 1857.

Davis, the youngest of ten children, was born in Fairview, Kentucky, but spent most of his childhood in Wilkinson County, Mississippi. His eldest brother Joseph Emory Davis secured the younger Davis's appointment to the United States Military Academy. Upon graduating, he served six years as a lieutenant in the United States Army. After leaving the army in 1835, Davis married Sarah Knox Taylor, daughter of general and future President Zachary Taylor. Sarah died from malaria three months after the wedding. Davis became a cotton planter, building Brierfield Plantation in Mississippi on his brother Joseph's land and eventually owning as many as 113 slaves. (Full article...)
