"New Nationalism" was a political philosophy introduced by Theodore Roosevelt in the early 20th century. It emphasized the need for a strong federal government to regulate the economy and protect social welfare. Roosevelt believed that the government should act as a mediator between competing interests, ensuring fairness and justice for all citizens. The movement aimed to address issues such as corporate monopolies, labor rights, and social justice. It advocated for reforms like women's suffrage and improved working conditions, reflecting a commitment to progressive ideals. New Nationalism sought to create a more equitable society through active government intervention.
