Georgia Re‑Admitted to the Union — 1870

Boeing’s engineering innovations help propel aviation from experimental novelty to essential infrastructure. Over the coming decades, the company becomes a central force in shaping modern flight, producing aircraft that transform transportation, warfare, and global connectivity. Its founding marks a turning point in American technological ambition and industrial capability.

Nixon Announces Wage and Price Freeze — 1971

Facing inflation and economic instability, President Richard Nixon declares a 90‑day freeze on wages and prices as part of his “New Economic Policy.” The measure shocks markets and temporarily stabilizes consumer confidence.

Economists debate the long‑term impact, but the policy marks a major expansion of presidential authority in economic management. The freeze reflects growing federal intervention during crises and sets precedents for future economic strategy. It becomes one of the most consequential economic decisions of the 20th century.
