List of world map changes

Map of the world

Below is a chronological list of political or geological events, which would alter the appearance of a world map. Changes usually include (but are not limited to) the alteration of borders, the creation and fall of states, changes of geographical names, as well as some unusually destructive natural disasters. Through the knowledge of such dates and events, the approximate year and age of a world map could be calculated and estimated.

Not all maps of the world of an age or period will be the same throughout the globe; as different mapmakers (or their employers) may have different views on the sovereignty and/or territorial integrity of the countries of the world and/or possess different levels of technological and/or geographical insight, the maps created by them might differ significantly.
