Page "Civil war" Paragraph 54

Ann Hironaka, author of Neverending Wars, divides the modern history of civil wars into the pre-19th century, 19th century to early 20th century, and late 20th century.

In 19th century Europe, the length of civil wars fell significantly, largely due to the nature of the conflicts as battles for the power center of the state, the strength of centralized governments, and the normally quick and decisive intervention by other states to support the government.

Following World War II the duration of civil wars grew past the norm of the pre-19th century, largely due to weakness of the many postcolonial states and the intervention by major powers on both sides of conflict.

The most obvious commonality to civil wars are that they occur in fragile states.
