This is a stupid question: where do you go to change your government type? I've done it once, but I seem to have forgotten what screen it is on.
You just click on the image of your country's flag on the top left of the screen. Then, click on the smaller images the show up along the top of the new "table". On one of them (I think it might be the one with the different idea), there should be your government type on the top. You can click on it and change to any possible government. Though you may not be able to switch at this current time.
Another question.
What are the main factors of morale? I just had a 35-regiment army get routed by a 26-regiment army. Both had commanders. However, I think I'm at Land Tech 8 and the other army was at Land Tech 10 or 11. How big of a factor is that?
To answer your question, if they were at land tech 11, they can use Galloglaigh Infantry, which are quite strong. Here are some other factors
I'm assuming you are playing a latin tech country, so here are a few things to keep in mind:
1. Keep your troops fully funded in a war. If they aren't being payed, they will have horrible morale, and will be almost certainly slaughtered.
2. When looking at the technology screen, keep in mind when you can get your next upgrade in troop types. Modern armies fight much more efficiently than their previous versions.
3. Having a good general may sometimes mean the difference between a defeat and a victory. Having the best general (at the stage you are in, you want a general with high shock skills) is a great boost to your armies.
4. You may want to consider taking some national ideas for the army. When a new idea becomes available (This idea is always my first choice), you may want to choose the "Military Drill" idea, granting you a +1 boost to your morale, which proves very useful indeed. It may also be in your interest (Once you get the required land tech of 7) to take National Conscripts, giving you a plus 50% manpower bonus. This will help you get more reinforcements to you armies.
5. When planning to fight a battle, take a look at the terrain. It is not a very good idea to attack an army of equal size in the Swiss Alps, or in another mountainous region. However, if you attack on some plains, the penalty for attacking will be much smaller. Just flip that around when defending.
I can't think of any more factors right now. I'm sure there are some I'm not thinking of, but whatever.
Hope this helps!
