Before the Battle of Chaeronea (338 BC), where Philip II of Macedon prevailed over a common Greek alliance, the city-states had been weakened by years of social and economic turmoil. To read the classical speeches in the Athenian assembly is to learn of the democracy’s constant struggles with declining revenues, insolvency, and expanding entitlements. Rome between the First Triumvirate (59 BC) and the ascension of Caesar Augustus’s autocracy (27 BC) was mostly defined by gang violence, chaos, and civil war, the common theme being a loss of trust in republican values. Russia was in a revolutionary spiral for nearly twenty years between 1905 and the final victory of the Bolsheviks in 1922, ending up with a cure worse than the disease. And Europe between 1930 and 1939 saw most of its democracies erode as fascists and communists gained power—eventually leading to the greater disaster of the outbreak of World War II.
The United States has seen periods of near fatal internal chaos—in the late 1850s leading up to the carnage of the Civil War, during the decade of the Great Depression between 1929 and 1939, and in the chaotic 1960s. Something similar is starting to plague America today on a variety of political, economic, social, and cultural fronts.
