Cuius regio, eius religio as the agreements of Westphalia decided in 1648 - or Whose realm, whose religion. This produced some stability, but not for long. You could read that line, after all, very personally and see what it demanded next: My realm, my religion.

Individuals — and the very birth of the idea of individualism was another heretical slap at the old institutions - could balance and contend and argue as equals. The notion that men were “created equal” became increasingly evident in this generation, even as establishing that equality triggered the French Revolution, the American Civil War and countless similar conflicts. Democratic systems aspired to enshrine this new balance, shifting countries from rule-by-birth to rule-by-majorities. In economics, markets reflected the new picture of power too. How good is that product? What is the price? Is there demand? became the essential questions, not Which Lord controls that field.
