Who was the Republican president elected in 1888 known for significant economic legislation?

Benjamin Harrison, elected as the Republican president in 1888, is recognized for his significant contributions to economic legislation during his term. One of his notable achievements was the passage of the McKinley Tariff Act of 1890, which raised tariffs on imported goods to protect American industries from foreign competition. This legislation reflected a strong protectionist policy that aimed to promote domestic manufacturing and was indicative of the economic context of the late 19th century when the United States sought to expand its industrial base. Additionally, Harrison supported the expansion of the Sherman Antitrust Act, aimed at curbing monopolies and ensuring fair competition in the marketplace. His administration's focus on such policies influenced the economic landscape of the country during that era.
