Ok so after forming a very successful sprawling Hispanic empire, I thought I would make a small guide for other player to get things going. This guide is intended for semi experienced players who have a fair grasp on the game mechanics. Ill do it in number format to make it easy to read.
How to get started
1. Before you unpause take note that the kingdoms of Portugal Leon and navarra are ruled by family members, and you will see you are the heir to their thrones. Immediately set up a intrigue assassination of the Portugal ruler. Drop gold on those who are 'on the line' about joining your plot.
2. Immediately declare holy war for the Islamic region to the south east of you. Fear not, your friends (while they live) will all join you, raise what you have and take those lands. Make sure its those lands directly in the south east of you, this will keep a lid on navarra and aragon, and seriously weaken them down the line while strengthening your own position.
3. Continue with your assassination these are your top priority, take out that portucale king, then hit leons king, if he has a heir assassinate him too so you become the heir before you bump your brother off. This will all take a bit of time so be patient and drop that gold. Help out in any holy wars in Spain against the Muslims.
Now you have portugal, Leon and the lands of castille, and have expanded at least a bit. Now what?
1. Congratulations your the fattest Christian kingdom now in Spain. The other remaining kingdoms should provide no threat to you (these should be aragon and Navarra and Barcelona) Since they are weaker and are busy with the Muslims.
2. Do not help out Barcelona with anything at all. let them rot, they are the second threat to you after the Muslims so don't let them expand if you can let them get smashed up by Muslim holy wars.
3. Continue to expand your realm via holy wars, smash those Muslims hard and as soon as your peace treaties expire. If you can hit another muslim leaders lands while a truce with another is still active do it. This war is akin to Blitzkrieg, you want to keep the muslims on their toes and so their levies dont replenish. if you lose a war dont worry, go back again asap, but this time make sure you got at lest 500G in the bank for mercs.
4. Once you have booted the majority of the muslims out, you can form the kingdom of andalusia. dont do this theres no point and it will just make vassals want more titles off you.
5. As soon as you can (usually once the muslims are out and you've got mallorca) form the empire of Hispania. Using my tactics above i did this with just my second king. This will be a proud moment for you if it was your first empire in the game you created. Use your newfound De Jure claims to get barcelona, navarra and aragon if any of them still exist to accept vassalage. If they do not, Crush them and put their heads on pikes for their insolence.
Further tips, and ramblings.
1. Set up Ultimogeniture as your succession laws, primogeniture for spain isnt that usefull you will most likely start god knows how many revolts and it would take you dangerously to your third kings to actually manage to implement this. You really dont want the hassle of factions while your on blitzkrieg across spain.
2. Kill unwanted children. If you have a awesome 13 year old son with good traits and healthy but your stupid wife decides to have 6 kids in 6 years straight even though your like 56 years old, have 5 of them executed, kill your wife and don't marry again.This is the medieval era times were ruthless.
3. Keep the king of France happy, in my games we are the best of friends and have gotten each other out of some serious trouble (i helped him fight off HRE, he helped me take a lot of north africa and speed up some of the wars in south spain, he even helped me defend against a Jihad for andalusia.)
4. once your Hispanic empire is done, the world is yours. I had a claim on england but didnt pursue it as i wanted a more Holy war oriented game. Maybe you would pursue it. Maybe you would invade france and aquitane. You are powerful enough now to hold down most other empires in the world using mercs (im making 41.5G a turn currently) and about 10k in troops you have, not to mention retinues up to 5k if you have legacy of rome DLC) Personally, im pushing into africa as i type, and am busy conquering mali, whilst i have a large portion of north africa down. Ill screenshot when i sort out fraps.
