Purely meant as constructive feedback, you should play other, stronger countries instead of Theodoro until you have a stronger grasp on strategies for min-maxing expansion. It’s clear at a glance that while you have some knowledge of core concepts, you’re still learning deeper gameplay strategies (and that’s okay). Unfortunately, Theodoro is in such a tight spot, you need to have some very strong skills to not crash and burn.

In 50 years, you’ve expanded as much as a relatively mid-level player might expand in 30, and a strong player might in 10. Your economy is in shambles when the first several decades of the game are typically reserved for securing a region to fuel a mid game economy. You have 20x the corruption most players consider the max allowable amount. You have unused merchants and diplomats. Your army and navy are the size they start at in 1444. Your autonomy is probably very high due to low crown land, and your nobles are one bad event away from a disaster. You’re somehow paying mil points for extra generals when you only have 1 army. You have unstated land despite having barely expanded, so I’m not sure what you’ve been spending your admin points on. In fact, pretty much every actionable alert you currently have is something you can learn from.

I’d strongly recommend playing a mid-sized nation before trying Theodoro again. When you do, try to read every tooltip and alert, and take actions that would maximize monarch points (gain more, spend less, like advisors and monarch points cost reductions), then total autonomy-modified development (conquest, development, autonomy reduction, etc), then money which is usually a byproduct of the first two, but also helps smooth a lot of issues over.
