That picture at the bottom of the previous page is the Kingdom of Aquitaine in 1218 shortly after the incorporation of the Duchy and Kingdom of Aragon.
I started as the Duke, in 1066 (coronation of the Bastard on Christmas Day). Guilhem managed to strengthen his hand within the realm, before eventually breaking away, founding his own kingdom, which only included Poitou, Gascony, Aquitaine and the Bourbon.
His son began the task of trying to consolidate all the Occitan lands under the crown of Bordeaux. First he had to reorganise the realm. A couple of overmighty vassals; and then a rather bitter defensive war against the vengeful Capets. To be honest, I was losing, badly. But then, a fight under the walls of Poitiers changed everything. I personally slew the king, and captured three of his dukes. War over, the French were off the table for a decade. Really promising ruler, went and died young on me. Wounds picked up at that glorious battle.
The next one (also Guilhem), was young enough that I had to sit through a lengthy minority. At this point, the French king was more powerful, so I needed opportunism to prosper. Luckily, there was a shit-fight with the Anglo-Normans, allowing me to sneak a victory on the southern bank of the Loire, landing the Auvergne in the process.
His son, called Louis, was the one who crushed the power of the French King. An Anglo-alliance neutered the Capets, perhaps permanently. I took the Duchy of Berry, and the Normans Flanders. I half suspect that their involvement in several crusades was an attempt to find breathing space. It didn't work. County after county, I chewed up the Duchy of Toulouse, while expanding my power within the realm - I think all the lower duchies now have ancestors descended from that first victorious duke who became a king. I had hoped to move against Brittany, but the English started to , so I concentrated on expelling France from the south. After that, long campaign was over, a new avenue opened up. My wife had a claim on the duchy of Dauphin. One of the many excommunicated emperors was facing enough wars and rebellions that I took it for my own. I sat back after that, strengthening while my threat rescinded. The only fly in the ointment was a female ruler, whose own son - a five star ruler in the making - was crippled and died in the war for Dauphin.
Eventually, Louis died at a grand old age. His already aged daughter succeeded in Aquitaine, while her mother ran Dauphin. Two years later, the queen was succeeded by her grandson. six months after that, he gained Dauphin when his great granny died. Seriously, that couple were very long lived.
The beginning of the reign required lots of charm. Female ruler, two year reign, now passed on to a nineteen year old. One with, frankly, shocking skills. Louis had got a decent set of kids and grandkids, but taken his eye off the ball after that generation. However, I've avoided any rebellions, with a combination of charm, force, and whacking great pay-offs. Holy War for Barcelona took me south of the Pyrenees, but the Emirate/Duchy was centred on Zaragoza, so I just got the county, and a load of vassal counts, who were a bit fractious, to say the least. I waited for another decadence revolt, then went for a holy war for Aragon. That's allowed me to form the Kingdom of Aragon and its two duchies. The duchy of Aragon has gone to my brother, who I'm hoping will loyally hold the line south of the Pyrenees. Once my threat dies down, I have a decision to make.
Where next? Finish the consolidation of the Occitan realm, by going for Provence? Finish off France, once and for all? Fight for Christendom, by pushing down the coast to Valencia?
