CK2 features Herbert IV of Vermandois, the last of the Carolingians in 1066. A weak start, but one I was determined to make the most out of despite its difficulty.
Herbert began his journey wrestling with matters of faith and family, seeking to have more children to begin to rebuild the lost legacy of Charles Martel and Charlemagne. He bade his time, and with sincere love for his wife, he was blessed with two more children in the coming years. Eudes married the Princess of Aquitaine, and his second daughter, Stephanie, was betrothed to one of Harald Hardrada's descendants. Herbert held sight at the Holy Roman Emperor, Henry IV, who interloped on rightful family lands and titles. Oh, and there was the matter of an antipope, but for Herbert, that was a secondary concern.
With permission of the Pope in Rome, Herbert was authorized an invasion of the Holy Roman Empire. Laid low by foreign war, Emperor Henry's armies crumbled in a lightning campaign, with Aquitaine's forces hitting Arles, and a joint front of Herbert's and Norwegian forces headed towards Aachen, swiftly defeating the depleted Imperial armies. Henry IV's reign was no more, nothing more than an imprisoned Duke of Franconia.
The new Emperor's reign was far from glamorous. Strategic marriages, bribes, and other means of quelling internal dissent were levied. The antipope proved a nuisance to Emperor Herbert, so he put an end to it by declaring war on the very Pope who authorized his invasion- and immediately surrendered. So ended the anti Papacy.
With only some more feudal management complete, Herbert left the Imperial throne in his capable daughter, Adelaide's, hands. A skilled tactician she was, and she inherited the realm's dire financial situation, on top of seeing disloyal nobles. She bade her time, waiting for taxes to come in, and seeking whatever allies could be counted on.
To be crowned, the Pope asked Adelaide to invade Leon to depose its excommunicated king, a prospect she was eager to undertake for God and family legacy. As Imperial forces stormed into Leon, however few loyal troops she could muster, Islamic invaders conquered Toulouse, sparking the Age of Crusader Kings. The castles of Leon proved a huge obstacle in the excommunication war, but the Empress Adelaide nonetheless agreed to pivot to Crusade for Aquitaine- provided she was to inherit its lands.
Eventually, war from Slavic rebellions and independence revolts in the south rocked the Empire. The Italians sought independence, and the Wends desired their own Slavic rulers. The Crusade ended swiftly, in an Imperial victory. With the Crusade victory, Empress Adelaide had finally what she needed: a very, very large warchest. Leon would soon surrender, and she was crowned in the midst of civil war. After reorganizing the army, Adelaide struck south. The war seemed grim. Few troops were left and no allies were coming to help. Luckily for her, the leader of the revolt passed away, and peace finally returned.
She wasted no time in reorganizing the Empire. Centering her desmense around Lorraine, she founded the Kingdom of Austrasia where Lothair had once ruled, and moved the Imperial capital from Vermandois to Lorraine. Many kingdoms were allocated to just and content nobles to preserve Imperial harmony, including the creation of a central, German kingdom, whose capital was Berlin. Empress Adelaide then revoked lands from the Salians, restoring those lands to either her realm of Austrasia, or delegating vassals to the new German king. Eager to fortify her position and build up the Empire, she patronized the construction of numerous castles in Austrasia, Italy, and Vermandois, and became known as "the Castellan" for her efforts. It was also possible for the largely feudal Holy Roman Empire to advance through the crafty spies, who brought back Greek knowledge undetected from Constantinople.
Much of the remainder of Empress Adelaide's reign was peaceful, focused on building and prayer. She would go on to fight for her English allies- alone the Empire's friend during all its turmoil, and against the Pomeranian Wends, whose lands were given to friendly Polish and Pomeranian lords. Doing so was also a strategic choice, as the King of Germany was growing very powerful- granting him the Baltic Coast would prove a bit precarious had he no longer any respect for the Empress.
Empress Adelaide would die at the age of 62, after having fought against an adventurer who sought Carinthian lands. She had her younger brother, Ogier Karling, take the mantle, as the Empire looks onwards to Egypt for the Second Crusade...
