What were different types of historical wars?

Throughout history, wars have varied significantly in type and scope. Some common categories include conventional wars, characterized by regular armies fighting in organized battles, such as World War I and II; guerrilla wars, which involve irregular combatants using unconventional tactics, as seen in Vietnam; civil wars, where factions within the same country fight for control or change, like the American Civil War; and colonial wars, which often involved imperial powers clashing over territories, such as the Napoleonic Wars. Additionally, there are religious wars, driven by ideological or religious differences, exemplified by the Crusades.
