# bio (long form, separated for readability)
bio: |
  Otto spent his early years in England and France as a follower of Richard the Lionheart, who made him Count of Poitou in 1196. With Richard's backing, he was elected King of Germany by one faction in 1198, triggering a decade of civil war that ended only when his rival Philip of Swabia was assassinated in 1208. He marched to Italy in 1209 and Pope Innocent III crowned him emperor, but the alliance shattered within a year when Otto moved to absorb the Kingdom of Sicily into the Empire. Innocent excommunicated him in 1210. Otto threw in with England against France and rode to catastrophic defeat at Bouvines in 1214. By 1215 most of his supporters had deserted him, and he spent his final three years in quiet retirement on his estates near Brunswick.
