Generally when a country starts running vassal states, though I suppose you could argue that it doesn't really apply until a country's economy will collapse if it doesn't keep expanding its holdings. You're already pretty well established as an imperial power by the time that's likely to become a problem, though. (In fact, Rome and the British Empire were both already on the way down when that became clear.)
