A time line of important events from the nineteenth century.
The time line below includes the events and developments covered in the essays in this publication (appearing in small capital letters), which are covered in depth in this chronologically arranged publication under the dates shown. More than 750 other important events and developments, are also included here. Each event is tagged by a general region or regions; by this means, the time line can be used to consider general trends in the same region over time. However, because many events, although occurring in one or two regions nevertheless had a global or cross-regional impact, they have been left in chronological order to facilitate a better understanding of simultaneous events and their occasional interaction. The abbreviation “c.” is used below to stand for “circa.”
