Long game
I first attacked the Moors. I captured all their European lands. I then changed my capital to Cordoba. I then got Pamplona from Portugal. The pope threatned to excommunicate me if I fight it further. I stopped but they attacked so they got excommunicated. So I was able to fight them. I took Portugals second and last piece of land and hence they got eliminated. I took 2 rebel cities and this marked my complete control of the Spanish peninsula. I also put 3 cogs in that narrow strait between Africa and Spain so the Moors can't go through. Later the Moors sent a diplomat and they offered a ceasefire anyways.
Next I made 3 more cogs and put a full army in it with 2 generals including my faction leader. We sailed up North to Irealnd. Dublin was a rebel city. I captured it. We went north-east to Scotland and captured the northmost rebel city. I captured a rebel city between England and scotland and hence Scotland and its only city is sorrounded. However they have a very strong army so I can't attack them...
England and Sicily offered to be my allies. I accepeted. But soon I will have to destory England.
Sorry I forgot to take a pic.
