Eras Beginning from 1816 to 1857 CE

This group gathers eras that began between 1816 and 1857 CE, placed among the eras of The Long Nineteenth Century. From 1816 to 1857 industrial growth, liberal reform and the expansion of European empires opened new named periods, among them the Victorian era in Britain, which this atlas dates from 1837. An era belongs here when its cited source gives a start date inside this span. It excludes eras that began earlier or later, which sit in the neighboring groups of the same period band, and it does not turn on how long an era lasted or how widely it is remembered.
