Tales from Saxony - Chapter V
Emperor Rudigar ends up dying at the age of 67 in the year 1034, after 36 years of reign. Unfortunately his son Frederik died before Rudigar, so his second grandson, a young Abo, becomes Emperor.
The first 4 years of Abo's reign serve to pacify the ambitions of various lords, most importantly those furthest from the imperial capital. For several years Abo asked the Pope for his presence for a coronation, but he continued to decline, as he tried to persuade Abo to send the imperial army south to war against the King of Italy, to regain former papal territories.
After years, Abo, tired of the Pope's demands, decides to appoint the Law of Free Investiture in the Empire, contradicting the Pope, who has no other choice but to crown Abo in exchange for making the Investiture of the Empire to be controlled by Rome again.
Emperor Abo's dynastic relative, Count Gelder of Mark, was once a descendant of House Liudolfinger with nothing to inherit. Since then, he has forged his own path as ruler. So he established a cadet branch of the Liudolfingers. From now on, he and all his offspring will be known as members of House Liudolfinger-Mark.
In 1048, Emperor Abo initiates an invasion of Poitou, on behalf of Count Ugues de Blois. 14.000 soldiers arrive in French lands, but Abo commands them to take the capital of the Kingdom of Burgundy at Rougermont. After an assault, the capital is taken, the imperial soldiers find the little Queen Hemma and her cousin, the daughter of King Liutpolt of Navarre. The lords of Burgundy have nothing to do but surrender Poitou in exchange for releasing their queen from imprisonment.
After the war, the Emperor began to change the imperial guard, composed mostly of light cavalry, and a minority of heavy cavalry, for a guard of pikemen and trained archers.
In the year 1053, missionaries from the Empire achieve the feat of performing mass baptisms in Tiundaland. Even though the priests write that they don't feel entirely convinced of the barbarians' sincerity, the ceremony ends up going well and Sweden officially becomes Catholic. King Gudrodr begins a grand ceremony in his capital, in the rest of Christian Europe he would now be known as 'the Confessor'.
