| Timeline of geopolitical changes | |
|---|---|
This is atimeline of geopolitical changes around the world between 1900 and 1999. It includes dates ofdeclarations of independence,changes in country name, changes ofcapital city or name, andchanges in territory such as theannexation,cession,concession,occupation, orsecession of land. Territorial conquests as a result of war are included on the timeline at the conclusion ofmilitary campaigns, but changes in the course of specific battles and day-to-day operations are generally not included. Changes inairspace andmaritime territory are included only when they are subject to a dispute.[a] Over 50% of the world's borders today were drawn as a result of British and French imperialism. The British and French drew the modern borders of theMiddle East, 80% of the borders ofAfrica, inAsia after the independence of theBritish Raj andFrench Indochina and the borders ofEurope afterWorld War I as victors, as a result of theParis treaties.[1][2][3]
