Before I started taking all of Arabia, Iran was pretty scared of my significant land gains in Europe. So like the sakōku phase in Japan's history, they had to isolate themselves from the outside world. Even though that meant no trading, it had to do until they could figure out ways to trade. It has been 15 years since Iran had isolated themselves, and they figured out how to trade. I do give credit to the Persians for their ingenuity, but now is their time to fall. This is going to be another series, just like the African Campaign. I will make the first part now, but I'll do the other parts over the days.
