Which reminds me, I realised earlier that this period of time is a single war! The Clone War! It isn’t Clone Wars at all! The Star Wars are a collection of wars, of which the Clone War is one such war, which contains multiple battles and crises. Like Yoda says at the end of Attack of the Clones, “Begun, the Clone War has.”
I can’t recall if it’s singular or plural in ANH but technically there are several wars going on around each other all tied into the main Republic vs CIS war. The Republic invasion of Mandalore, the Shadow Collective vs. Mandalorian war, the CIS vs. the Nightsisters, the Republic vs. various pirates and slavers, the CIS vs. the Hutts, the Onderron rebels vs. the CIS.
It’s an oddity it’s referred to as a ‘clone’ war in the first place where a term like ‘Galactic War’ would suite better, though that is mostly ANHs fault. But the Republic vs. CIS war is the trigger for the other side-wars both sides are fighting so it can be said to be a collection of wars.
