This is a list of conflicts in Europe ordered chronologically, including wars between European states, civil wars within European states, wars between a European state and a non-European state that took place within Europe, and global conflicts in which Europe was a theatre of war. There are various definitions of Europe and in particular, there is a significant dispute about the eastern and southeastern boundaries, specifically about how to define the countries of the former Soviet Union. This list is based on a wide definition that includes much of the interface between Europe and Western Asia.
