{{short description|None}}

{{Incomplete list|date=February 2011}}

The following is a '''list of border conflicts''' between two or more countries. The list includes only those fought because of border disputes. See [[list of territorial disputes]] for those that do not involve fighting. 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 the [[Middle East]], 80% of the borders of [[Africa]], in [[Asia]] after the independence of the [[British Raj]] and [[French Indochina]] and the borders of [[Europe]] after [[World War I]] as victors, as a result of the [[Treaty of Versailles|Paris treaties]].<ref name=Manning-1990>{{cite book |last=Manning |first=Patrick |title=Slavery and African Life: Occidental, Oriental, and African Slave Trades |publisher=Cambridge University Press |location=London |year=1990}}</ref><ref name="Lovejoy, Paul E. 2012">Lovejoy, Paul E.
