The Reagan Era or Age of Reagan is a periodization of recent American history used by historians and political observers to emphasize that the conservative "Reagan Revolution" led by President Ronald Reagan in domestic and foreign policy had a permanent impact. It overlaps with what political scientists call the Sixth Party System. In Wilentz's (2008) view, Reagan dominated this stretch of American history in the same way that President Franklin Roosevelt and his New Deal legacy dominated the four decades that succeeded it. The Reagan Era included ideas and personalities beyond Reagan himself; he is usually characterized as the leader of a broadly based conservative movement whose ideas, whether good or bad, dominated national policy making in areas such as taxes, welfare, defense, the federal judiciary and the Cold War. Liberals generally lament the Reagan Era, while conservatives generally praise it and call for its continuation in the 21st century.
Campaigning for the Democratic nomination in 2008, Barack Obama interpreted how Reagan changed the nation's trajectory:
"I think Ronald Reagan changed the trajectory of America in a way that Richard Nixon did not and in a way that Bill Clinton did not. He put us on a fundamentally different path because the country was ready for it. I think they felt like with all the excesses of the 1960s and 1970s and government had grown and grown but there wasn't much sense of accountability in terms of how it was operating. I think that people... he just tapped into what people were already feeling, which was we want clarity, we want optimism, we want a return to that sense of dynamism and entrepreneurship that had been missing."
Most historians begin the era in 1980, when Reagan was elected president. Historians usually probe back into the 1970s for the origins of the Reagan Era. For example, Kalman (2010) explores multiple crises of the 1970s that eroded confidence in liberal solutions: the rise of the religious right and the reaction against feminism and the ERA; grass roots reactions against busing ordered by federal judges; the defeat in Vietnam, the collapse of détente and fears of Soviet power; the challenge of imported cars and textiles, the deindustrialization of the Rust Belt, soaring inflation, stagflation, and the energy crisis, as well as the humiliation the nation suffered during the Iran hostage crisis and the sense of malaise as the nation wondered if its glory days had passed. She shows step by step the process by which one political alternative after another collapsed, leaving Reagan standing.  The ending point is usually seen as the election of Democrat Barack Obama in 2008. However, the results of the 2010 midterms in which the Republican Party produced the greatest landslide of either party in any midterm election since 1938, seem to suggest that the nation is still largely continuing the Reagan legacy of conservative policies. The Clinton presidency (1993-2001) is often treated as an extension of the Reagan Era, as is the Bush presidency (2001-2009). Historian Eric Foner noted that the Obama candidacy in 2008 "aroused a great deal of wishful thinking among those yearning for a change after nearly thirty years of Reaganism."
Tom Clancy wrote three best-selling novels that illuminate the Reagan era: The Hunt for Red October (1984), Red Storm Rising (1986), and The Cardinal of the Kremlin (1988). They reflect Reagan-era Cold War values. The Soviet Union as an evil empire and the superiority of American values and technology are all themes both of Clancy's thrillers and Reagan's rhetoric. Policy elites used these novels (and the filming of one of them) to promote their ideas of national security to the American public.
Many scholars take an international perspective, linking the Reagan Era with the Thatcher Era in Britain. As socialist scholar explained,
- Throughout many of the capitalist democracies in Western Europe and in North America, the recession that began with the sharp rise in petroleum prices in 1973-74 signaled an epochal shift in the patchwork of growth- based economic and social policies....The demise of Keynesianism which followed meant far more than the obsolescence of an economic doctrine that had been used to justify a broad range of economic policies. It represented a significant retreat from a vision of society - the Keynesian welfare state - that had motivated state strategies to harmonise interests through social policy, to politically regulate the market economy and thereby reduce class and diverse social conflicts, and to promulgate for the state a tutelary role in securing business and trade union acquiescence (and less commonly approval) for a limited set of important economic policies.
Historian Doug Rossinow reported in 2007, "As of this writing, among academic historians, the Reagan revisionists—who view the 1980s as an era of mixed blessings at worst, and of great forward strides in some renditions—hold the field." Other scholars agree on the importance of the Reagan Era.
