Lothaire II is a recommended character in the Karling-centric scenario who starts off in quite a bit of a bind. For one, your kingdom is sandwiched between your uncles’ kingdoms; though it isn’t likely for them to begin harassing you until much later.
Your biggest dilemma will be Lothaire’s family matters. His wife has been unable to conceive children of their own. While his love affair with Waldrada has bestowed him with bountiful children. Due to his relationship with the church, he’s been unable to file for a divorce. Nor has he been able to legitimize his children.
Lothaire’s above-average intrigue is likely to help keep plots and schemes against him at bay. But without a proper heir, Lothaire will lose his lands to his brother Louis the Younger once the former dies. You can take more active action by trying to legitimize your bastards and divorcing your wife. With some good intrigue-work, along with other efforts, you might just secure Lothaire’s line.
Lothaire II is the son of Lothaire I (how original). His father arranged a political marriage for him with Teutberga, with whom he would have no children. In the partition of Lothaire I’s realm, Lothaire II would receive Middle Francia (later known as Lotharingia or Lorraine). After the death of his younger brother Charles, Lothaire II would divvy up his territories with Louis the Younger.
Caught-up with Love
Lothaire II spent much of his time attempting to annul his marriage with Teutberga. He would seek support from his many relatives, including Charles the Bald and Ludwig the German. A second reason for Lothaire II’s effort into this annulment was to do with his love affair. Waldrada was Lothaire II‘s long-time love interest. The issue would remain for years with multiple sides pulling strings to opposing outcomes.
Eventually, Lothaire would pressure Teutberga to agree to the divorce. She’d approach the newly elected Pope Adrian II for an annulment. However, Lothaire II would be caught by illness before he could further proceedings. He would soon die on his way back from Rome, after his audience with the Pope.
Due to the nature of his son’s illegitimacy, Louis the Younger would become the heir over his realm. But if you’ve read on Charles the Bald or Ludwig the German, then you’d know Lotharingia was split between the two uncles. Lothaire II would not leave much of a legacy, aside from a life worthy of a cautionary tale; now I wonder if there is a tale inspired by his life?
