What was The Harding's presidency marked to be the end of?

Warren G. Harding's presidency, which lasted from 1921 until his death in 1923, is often marked by the end of the Progressive Era in American politics. His administration favored a return to "normalcy" after World War I, emphasizing limited government and pro-business policies, which shifted the focus away from progressive reforms. His presidency was also marred by scandals, such as the Teapot Dome scandal, which further tainted the legacy of the era and underscored the need for reform in government integrity.
