The Golden Age of Freethought describes the socio-political movement promoting freethought that developed in the mid 19th-century United States.
 The period roughly from 1875 to 1914 is referred to as "the high-water mark of freethought as an influential movement in American society".

The Polish Golden Age refers to the period from the late 15th century Jagiellon Poland to the death of the last of the Jagiellons, Sigismund August in 1572.
 Some historians claim that the Golden Age lasted until the mid-17th century, when in 1648 the Polish-Lithuanian Commonwealth was ravaged by the Khmelnytsky Uprising, and Swedish invasion.
 During its Golden Age, the Commonwealth became one of the largest kingdoms of Europe, stretching from modern-day Estonia, to Moldavia and Silesia.
 Its army was able to defend the realm against numerous Teutonic knights, Turkish, Swedish, Russian, and Tatar invasions.
 The country prospered thanks to its enormous grain, wood and salt exports.
