To me sounds a lot like Roman rise & conquest of Italy on a big zoom in on Italy, a bit of transalpine Gaul, Epirus & Sicily would enable to include Gallic & Pyrrus invasions + maybe 1st Punic war.

But the image seems distinctly Eastern -> Mithradatic wars, Diadochi or Alexander campaign?.

Someone at TWC had what I think is a neat idea (or at least this is my interpretation of their idea): several mini-Revolt campaigns Spartacus, Carthaginian Mercenary war, Jewish revolt/s (vs Seleucids and/or vs Rome)

A Rise of Persia could be really neat too.
