When Americans knew classical history, they could reach beyond partisan differences by drawing on the shared roots of our civilization. American students once learned, for example, about the Greek victory at Marathon in 490 B.C. This kept Greece from being swallowed up by the Persian Empire and ushered in the Golden Age of Athenian democracy which, for all its shortcomings, was a pathbreaking achievement.
Democratic Athens, counterbalanced by Sparta’s tripartite system, led to broad-based polities and ultimately the Roman Republic. From there we trace a clear line to Magna Carta and the Renaissance republics, to the Enlightenment, and ultimately to the American Founding in the years around 1776.
