1.
war; warfare; turmoil of war
The state of widespread warfare and the chaos and destruction it brings. Emphasizes the prolonged, chaotic nature of conflict rather than a single battle or military operation.
Usage
戦乱 evokes extended periods of conflict and chaos, not a single battle. It is commonly used in historical narratives, particularly about Japan's Sengoku period (戦国時代) or other prolonged civil wars. Compare with 戦争 (war), which is a more general and modern term, and 内乱 (civil war/rebellion), which specifies internal conflict.
