The Indiana Civil War refers to the role and impact of the state of Indiana during the American Civil War (1861-1865). Indiana was a significant contributor to the Union effort, providing over 200,000 soldiers to the Union Army. The state was also home to various military camps and training facilities, which played a crucial role in preparing troops for battle. In addition to military contributions, Indiana experienced social and economic changes due to the war. The conflict spurred industrial growth and increased political activism, particularly among abolitionists and women's rights advocates. These developments shaped Indiana's post-war society and economy.
