What is a civil war?

• A. A war between two countries
• B. A war between two groups in the same country
• C. A war fought in a single city
• D. A war that is fought only with nonmilitary means

Answer: (B)

A civil war is an armed conflict between organized groups within the same country. The defining feature is that the fighting happens inside one nation and involves groups competing for political control, governance, or major social change. This internal struggle distinguishes it from wars between different countries, which are international wars, and from conflicts that aren’t about armed fighting at all.

The best answer fits this idea exactly: it describes a battle or war waged by factions within the same nation, rather than between separate countries.

The other options don’t fit because: a war between two countries is an international or interstate war, not a civil war; a war fought in a single city could occur in any type of war and isn’t what defines civil war; and a war fought only with nonmilitary means wouldn’t be a war at all, since true war involves armed conflict.
