Colonial Era and the American Revolution
The Colonial period and the founding generation are among the most heavily tested segments of US history in NHBB. Essential knowledge includes the causes and course of the American Revolution (the Stamp Act, the Intolerable Acts, Lexington and Concord, the Declaration of Independence, the role of France and Spain), and the major founders: Washington as commander and president, Jefferson as author of the Declaration and the Louisiana Purchase, Adams and the XYZ Affair, Hamilton's financial system and the First Bank of the United States, and Madison's role in drafting the Constitution. The Articles of Confederation, the Constitutional Convention of 1787, and the ratification debates (including the Federalist Papers, whose authorship and arguments are frequently tested) are all recurring NHBB topics.
The Early Republic Through the Civil War
The antebellum period is dense with testable material. The Missouri Compromise of 1820, the Compromise of 1850, and the Kansas-Nebraska Act of 1854 are the three critical attempts to manage sectional conflict over slavery, each with distinct provisions and consequences. The Mexican-American War, the Dred Scott decision, and John Brown's raid on Harpers Ferry form a chain of escalating crises. The Civil War itself demands thorough knowledge: Lincoln's war aims and the evolution of emancipation policy, the major campaigns and turning points (Antietam, Gettysburg, Vicksburg, Sherman's March to the Sea), the leadership of Grant and Lee, and the political debates over Reconstruction that followed the war's conclusion. The Emancipation Proclamation — its limited legal scope, its strategic purpose, and its symbolic significance — is a classic NHBB question topic.
Reconstruction Through the Progressive Era
Reconstruction (1865–1877) is often underestimated by competitors. The 13th, 14th, and 15th Amendments, the Freedmen's Bureau, Radical Republican policy, the impeachment of Andrew Johnson, and the compromise of 1877 that ended Reconstruction are all testable. The subsequent Gilded Age brought the rise of industrialists (Carnegie, Rockefeller, J.P. Morgan), the emergence of labor unions, and the Supreme Court cases that entrenched racial segregation: Plessy v. Ferguson (1896) is a perennial NHBB question. The Progressive Era of the early 20th century — the Sherman Antitrust Act, the muckrakers, Teddy Roosevelt's trust-busting, Woodrow Wilson's New Freedom agenda — rounds out this period. US entry into World War I and the subsequent debate over the League of Nations connect this era to global history.
WWII, the Cold War, and Civil Rights
The mid-20th century is tested intensively. For World War II: FDR's Lend-Lease policy, the attack on Pearl Harbor, the internment of Japanese Americans, D-Day and the European theater, island-hopping in the Pacific, the Manhattan Project, and the decision to use atomic bombs on Hiroshima and Nagasaki. For the Cold War: the Truman Doctrine and Marshall Plan, NATO, the Korean War, McCarthyism, the Cuban Missile Crisis, the Vietnam War from Eisenhower through Nixon, and détente. For the Civil Rights Movement: Brown v. Board of Education (1954), Rosa Parks and the Montgomery Bus Boycott, the Little Rock Crisis, the sit-ins, Freedom Riders, the March on Washington and King's "I Have a Dream" speech, the Civil Rights Act of 1964, and the Voting Rights Act of 1965. Each of these deserves individual attention, as questions often begin with specific legal provisions, speeches, or individual names before arriving at the familiar landmark.
Landmark Supreme Court Cases and Presidential Doctrines
NHBB regularly tests the Supreme Court as an institution. The most frequently appearing cases: Marbury v. Madison (establishing judicial review), McCulloch v. Maryland (implied powers), Plessy v. Ferguson (separate but equal), Brown v. Board of Education (overturning Plessy), Engel v. Vitale (school prayer), Miranda v. Arizona (Miranda rights), Roe v. Wade, and United States v. Nixon (executive privilege during Watergate). Presidential doctrines are similarly tested: the Monroe Doctrine, the Truman Doctrine, the Eisenhower Doctrine, the Nixon Doctrine, and the Carter Doctrine each have specific contexts and provisions that questions will describe before naming the doctrine. Knowing which president articulated which foreign policy principle, and why, is essential preparation.
