What Is Presidential History?

Presidential history is the study of the American presidency — the individuals who held the office, the decisions they made, the crises they faced, and the ways the institution itself has changed from 1789 to the present. It sits at the intersection of political history, biography, constitutional law, and the broader story of American democracy.

An Office Unlike Any Other

When the Constitutional Convention met in Philadelphia in 1787, they had a problem. The whole point of the Revolution was rejecting monarchy. But the Articles of Confederation had proven that a government without a strong executive was too weak to function. They needed a leader who wasn’t a king.

What they invented was genuinely novel. The presidency combined the roles of head of state and head of government in a single person — elected, term-limited (eventually), and constrained by constitutional checks. No European model quite matched it. The framers were making it up as they went, and they knew it.

George Washington understood this better than anyone. Nearly every decision he made set a precedent. He chose to be called “Mr. President” rather than anything grander (John Adams suggested “His Highness the President of the United States and Protector of the Rights of the Same,” which thankfully died in committee). He established a cabinet, set the tone for executive-legislative relations, and — most importantly — voluntarily left after two terms. That last act may have been his greatest contribution.

The Early Republic: Establishing the Rules

The first six presidents — Washington, Adams, Jefferson, Madison, Monroe, and John Quincy Adams — were essentially working out what the job actually was. The Constitution described presidential powers in deliberately vague language. Article II grants “executive power” without fully defining it, makes the president commander-in-chief without specifying what that means in practice, and requires that the president “take care that the laws be faithfully executed” without saying how.

Jefferson tested the boundaries almost immediately. The Louisiana Purchase in 1803 — buying 828,000 square miles from France for $15 million — had no clear constitutional authorization. Jefferson, a strict constructionist, knew this. He did it anyway. The precedent: when a good enough deal comes along, constitutional scruples can be… flexible.

Andrew Jackson (1829-1837) transformed the presidency from a gentlemanly institution into a populist one. He was the first president from the frontier, the first to claim a direct mandate from “the people,” and the first to use the veto aggressively as a policy tool. Previous presidents vetoed bills only when they believed them unconstitutional. Jackson vetoed bills he simply disagreed with. That distinction matters enormously.

The Civil War and the Expansion of Power

Abraham Lincoln’s presidency (1861-1865) represents the most dramatic expansion of executive power in American history. Faced with secession and civil war, Lincoln suspended habeas corpus, issued the Emancipation Proclamation by executive order, spent money Congress hadn’t appropriated, and blockaded Southern ports — all without explicit constitutional authority.

Was it legal? Debatable. Was it effective? The Union survived. Lincoln’s presidency established a principle that would echo through subsequent crises: in emergencies, presidents act first and seek legal justification later.

The post-Civil War period, by contrast, saw relatively weak presidents. Congress dominated the federal government from roughly 1865 to 1901. Presidents like Rutherford B. Hayes, Chester Arthur, and Benjamin Harrison are obscure today partly because the office itself was diminished during their era. The Speaker of the House often held more real power than the president.

The Modern Presidency Emerges

Theodore Roosevelt (1901-1909) changed the game. He articulated the “stewardship theory” of the presidency — the idea that the president could do anything not specifically prohibited by the Constitution, rather than only what was specifically authorized. He busted trusts, built the Panama Canal, established national parks, and projected American power globally. He also gave the presidency something it hadn’t consistently had before: star power.

Woodrow Wilson expanded presidential authority further through World War I, creating federal agencies, implementing the draft, and suppressing dissent (the Espionage and Sedition Acts were pretty extreme, to put it mildly).

But the real watershed was Franklin D. Roosevelt. FDR’s presidency (1933-1945) was so consequential that historians often divide the institution into “pre-FDR” and “post-FDR.” During his tenure:

• The federal government grew massively through the New Deal
• The executive branch expanded from a few hundred employees to tens of thousands
• The president became the primary legislative agenda-setter
• Executive orders became a major governing tool (FDR issued 3,721 — more than any other president)
• The two-term tradition was broken (he won four elections)

FDR created the modern expectation that the president is responsible for the economy, for national morale, and for solving problems that previous generations considered beyond federal authority. That expectation has never gone away.

The Cold War Presidency

The post-World War II era gave presidents enormous new powers. The National Security Act of 1947 created the CIA, the National Security Council, and the Department of Defense — all under presidential control. The president now had intelligence capabilities, military reach, and decision-making authority that would have been unimaginable to the founders.

The Cold War also normalized presidential war-making without congressional declarations. Truman sent troops to Korea without asking Congress. Kennedy and Johnson escalated Vietnam involvement through executive action. The War Powers Resolution of 1973 was supposed to reassert congressional authority over military commitments, but presidents of both parties have largely ignored it.

The imperial presidency — historian Arthur Schlesinger Jr. coined the term in 1973 — was real. Nixon took it to its logical extreme, claiming that “when the president does it, that means it is not illegal.” Watergate proved otherwise, but the underlying expansion of presidential power continued under subsequent administrations.

Presidential Rankings and Legacy

Historians love ranking presidents, and these rankings reveal as much about the rankers as the ranked. Still, some patterns hold across almost all surveys:

Consistently top-tier: Lincoln, Washington, FDR. These three managed existential crises — civil war, national founding, depression and world war — and the nation survived.

Consistently bottom-tier: James Buchanan (who dithered while secession approached), Andrew Johnson (whose Reconstruction vetoes set back civil rights for generations), and Franklin Pierce (who inflamed sectional tensions over slavery).

The risers: Dwight Eisenhower was once considered a do-nothing president. Declassified documents revealed he was actually a sophisticated strategist who managed the Cold War, built the Interstate Highway System, and kept the country out of several wars. Ulysses Grant has also risen, with recent scholarship emphasizing his civil rights record.

The fallers: Woodrow Wilson has dropped as historians reckon more seriously with his racism and his suppression of civil liberties during World War I. Andrew Jackson’s treatment of Native Americans — particularly the Trail of Tears — has increasingly overshadowed his democratic populism.

The Presidency in the Media Age

Television transformed the presidency. John F. Kennedy’s telegenic debate performance against Richard Nixon in 1960 demonstrated that how a president looked and sounded mattered as much as policy positions. Ronald Reagan, a former actor, turned televised communication into a presidential art form.

The 24-hour news cycle, starting with CNN in 1980, made the president a constant presence in American life. Social media accelerated this further. The modern president communicates directly with the public multiple times daily — a far cry from the era when presidential statements were rare and carefully prepared.

This constant visibility has had mixed effects. Presidents can rally public opinion faster than ever. But they’re also subject to constant scrutiny, rapid backlash, and the erosion of the mystique that once surrounded the office.

What Presidential History Teaches

Studying presidential history isn’t just learning names and dates. It reveals patterns.

Crisis creates expansion. Every major national emergency — the Civil War, the Great Depression, World War II, 9/11 — has expanded presidential power, and that power rarely contracts fully when the crisis ends.

Character matters, but so does context. Great presidents tend to be those who faced great challenges. James Polk might have been brilliant, but he governed during relatively calm times and is therefore obscure.

The office shapes the person as much as the person shapes the office. Presidents who enter with limited foreign policy experience often become heavily focused on foreign affairs. The daily intelligence briefings, the military command authority, the diplomatic responsibilities — the job pulls you toward certain priorities regardless of your original agenda.

And perhaps the most sobering lesson: the presidency is simultaneously the most powerful position on Earth and remarkably constrained. Congress controls the budget. The courts interpret the law. The states retain enormous authority. Public opinion limits what’s politically possible. The president proposes; everybody else disposes.

That tension — between enormous power and constant constraint — is the central drama of presidential history. It’s what makes the office endlessly fascinating and endlessly frustrating, for the people who hold it and the people who study it.

Frequently Asked Questions

Who is considered the greatest U.S. president?

Historians consistently rank Abraham Lincoln, George Washington, and Franklin D. Roosevelt as the top three. Lincoln preserved the Union during the Civil War and ended slavery. Washington established presidential norms that lasted centuries. FDR led the country through the Great Depression and most of World War II. Rankings shift over time — Dwight Eisenhower, for instance, has risen significantly in recent decades.

How has presidential power changed over time?

Presidential power has expanded dramatically since 1789. Early presidents deferred heavily to Congress. The modern presidency — beginning roughly with FDR — concentrates far more authority in the executive branch, including expanded war powers, executive orders, and a large federal bureaucracy. The number of executive orders, signing statements, and unilateral military actions has grown substantially since the mid-20th century.

How many U.S. presidents have been assassinated?

Four: Abraham Lincoln (1865), James Garfield (1881), William McKinley (1901), and John F. Kennedy (1963). Several others survived assassination attempts, including Andrew Jackson, Theodore Roosevelt (who finished a speech after being shot), Gerald Ford (twice in 17 days), and Ronald Reagan.

What is the 22nd Amendment?

Ratified in 1951, the 22nd Amendment limits presidents to two terms in office. It was a direct response to Franklin D. Roosevelt winning four consecutive elections (1932-1944). Before FDR, the two-term limit was merely a tradition set by George Washington, who voluntarily stepped down after two terms.
