In my current game, I am at Peace with Rome and have been consistently sending my caravans to them (btw, that paid off really well in terms of gold, so I’d highly recommend caravans!). In my current 85 years into the game, I see a lot of Roman armies surrounding the borders of my two cities. Either they are planning a hostile takeover but unable to do so because of the Peace pact between us or the AI is stuck in an infinite loop and does not know what to do. They should be declaring war on my neighbour, the Assyria. This made me nervous and I am investing all of my orders to build an army for an impending attack instead of working on something else.
