A federal law that restricted the power of labor unions — banning certain strikes, requiring union leaders to swear they weren't communists, and allowing the president to delay strikes that threatened national safety. Significant because it rolled back union power gained under the New Deal and showed growing anti-communist sentiment.

United Nations (1945)

An international organization founded after WWII with the goal of maintaining world peace, promoting cooperation, and preventing future global wars. The U.S. was a founding member.

"Iron Curtain"

NATO (1949)

A military alliance of Western nations — including the U.S., Canada, and Western European countries — agreeing that an attack on one is an attack on all. Significant because it was America's first peacetime military alliance and a cornerstone of the strategy to contain Soviet expansion in Europe.

Korean War (1950–53)

After communist North Korea invaded South Korea, the U.S. led a UN force to defend the South. The war ended in a stalemate with Korea still divided at the 38th parallel. Significant because it was the first "hot" conflict of the Cold War and established the U.S. policy of fighting communism militarily.

Space Race (1957–69)

A competition between the U.S. and Soviet Union to achieve superiority in space exploration.

Significant because it drove massive investment in science and technology and was a key Cold War battleground for global prestige.

Marshall Plan (1948)

Significant because, while much of it failed in Congress, it extended the legacy of FDR's New Deal and set the stage for later liberal reforms.

Rosenberg Case (1953)

Significant because it marked the formal beginning of the U.S. policy of containment and a commitment to fighting communism globally.

Levittown

Federal Highway Act of 1956

Signed by Eisenhower, it authorized the creation of the 41,000-mile Interstate Highway System, the largest public works project in U.S. history.
