Which person is referred to as the "father of the American system"?

Henry Clay is referred to as the "father of the American system" due to his significant role in advocating for a comprehensive national economic plan in the early 19th century. This American System was aimed at promoting national economic growth and consisted of three main components: a strong banking system to provide credit, a protective tariff to support American manufacturing, and internal improvements to enhance transportation networks across the country.

Clay’s vision sought to unify the growing nation and facilitate economic cooperation among its regions. He believed that these measures were necessary to foster industry, improve infrastructure, and cultivate a sense of national identity. His efforts in Congress and his influence in shaping policies during the era of the early republic firmly established his legacy as a key figure in American economic development.
