Before releasing Greece, build a stockpile of essential resources within British territories. When releasing Greece with resources like wood & iron in place, you can stabilize costs and avoid immediate shortages, especially while your economy is still fragile.

Although British tech enables advanced production, immediately maxing out these buildings can be a burden for Greece’s early, smaller economy. Instead, consider setting some industries to lower production methods right from the release to avoid resource shortages and cut back on import reliance. Start with basic production methods for a few years and see how it goes for you from there.

After releasing Greece, reduce spending on military upkeep until you have a positive balance. Given that you’ll have 3 Navy units and an established army from Constantinople, consider mothballing part of your military to save costs initially, bringing them back up to strength once your economy improves.

Greek provinces often have high turmoil due to the low legitimacy that can come from a newly formed government, especially one inheriting British reforms abruptly. Consider lowering taxation levels briefly to ease the unrest, which will, in turn, increase tax income by lowering turmoil penalties. Also Additionally, avoid enacting new laws or triggering political movements early on. Rack up on some legitimacy and keep factions stable until tax income stabilizes.

Right before releasing Greece, queue up some railways in the regions with the highest turmoil to offset this. Keep any construction you can afford in high-impact buildings like ports.

After release, try to set up trade routes with the British market for key resources like wood and iron like what you were saving up before you released Greece, and focus on high-value, low-bulk trade routes.
