Frequently Asked Questions
Both are correct and used interchangeably. 'World War One' (or 'World War I') is slightly more common in the UK, while both are equally common in the US.
Yes, it is often used in business, sports, or media contexts to describe an intense, large-scale competition (e.g., 'the streaming world war'). When used metaphorically, it is not capitalised.
We use the indefinite article 'a' for the general concept or a hypothetical one (a third world war). We capitalise and omit the article when using it as the proper name for the specific historical events (World War Two).
A 'world war' is distinguished by the truly global scale of its participant nations (from multiple continents) and theatres of combat, and its direct impact on the entire international system, as opposed to a large regional war.
