Henry Clay was a prominent American statesman in the early 19th century known as "The Great Compromiser". He advocated for the American System to promote economic growth which included high tariffs, a national bank, and federal funding for infrastructure projects. The American System aimed to strengthen the nation by developing domestic industry and markets. However, it ultimately failed after President Madison vetoed federal funding for infrastructure as unconstitutional, leaving individual states without means to build roads. This caused the national market envisioned by the system to not fully develop and intensified regional divisions.
