President Ronald Reagan served as the 40th President of the United States from 1981 to 1989, known for his conservative policies and strong leadership style. His administration focused on reducing the size of government and deregulating various industries, which had a significant impact on the federal bureaucracy and its operations during that time. Reagan's approach to governance emphasized supply-side economics, often referred to as 'Reaganomics', and he believed in empowering state and local governments over federal oversight.
