99.237.236.218 (talk) chipmunk that logic doesn't follow imo. I would agree that palestine's symbolic declaration did not change the world map and therefore doesn't make sense on this list. the other entry is about a country changing its name. that changes the world map. |

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 nations, the 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.
Note that 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.
