Henry Mason Mathews was an American military officer, lawyer, and politician in the U.S. State of West Virginia. Mathews served as 7th Attorney General of West Virginia (1873–1877) and 5th Governor of West Virginia (1877–1881), being the first former Confederate elected to the governorship in the state. Born into a Virginia political family, Mathews attended the University of Virginia and afterward practiced law before the outbreak of the American Civil War. When Virginia seceded from the United States, in 1861, he volunteered for the Confederate States Army and served in the western theater as a major of artillery. Following the war, Mathews was elected to the West Virginia Senate, but was denied the seat due to state restrictions on former Confederates. Mathews participated in the 1872 state constitutional convention that overturned these restrictions, and in that same year was elected attorney general of West Virginia. After one term, he was elected governor of West Virginia.

The Panic of 1873 was a financial crisis that triggered an economic depression in Europe and North America that lasted from 1873 to 1877 or 1879 in France and in Britain. In Britain, the Panic started two decades of stagnation known as the "Long Depression" that weakened the country's economic leadership. In the United States, the Panic was known as the "Great Depression" until the events of 1929 and the early 1930s set a new standard.
