Question: How old was the Duke of Saxony when he appointed Adolf I to hold Holstein and Stormarn? Passage:He was appointed to hold as fiefs Holstein and Stormarn, including Hamburg, by Lothair, Duke of Saxony, in 1111. By this appointment Adolf became the leader of the defence of Germany against the Wagri. Allied with Henry, the prince of the Obotrites, he repeatedly waged war on Wagria and the Rugians. After Henry's death (1127), Adolf remained allied with his sons Canute and Sventepolk, but they were soon dead and Lothair, by then King of Germany, had made Canute Lavard, a Danish prince, Duke of Schleswig. Feeling his authority threatened by the Danish upstart, Adolf attacked his castle of Albergs, captured the garrison, and destroyed its defences. He left his counties intact to his second son, Adolf II, since his eldest, Hartung, had been killed in the Second Battle of Chlumec in 1126.

Question: Which game in the 90s that Yuri is a playable character in sold the most copies? Passage:Yuri is also a playable character in The King of Fighters series first as part of the Women Fighters Team along with Mai Shiranui and King participating in the annual King of Fighters tournaments. In The King of Fighters '96, Yuri is requested by Takuma to participate in the Art of Fighting Team along with Ryo and Robert as Takuma decided to retire from the team. The King of Fighters '98 too features Yuri playable with her Art of Fighting 2 moveset as a hidden character. Due to the new rule that teams must be composed of four members, Takuma returns to the Art of Fighting Team in The King of Fighters '99. In The King of Fighters 2000, Yuri returns to the Women Fighters Team along with Mai, Hinako Shijou and Kasumi Todoh, having asked King to replace her in the Art of Fighting Team wanting more independence. Yuri once again returns to the Art of Fighting Team in The King of Fighters 2001 wanting to win the prize money to help Robert with several economical problems his company has. Although The King of Fighters 2002 does not feature a storyline, Yuri is once again in the Women Fighters Team with Mai and May Lee, but was moved back to the Art of Fighting Team in the remake, The King of Fighters 2002: Unlimited Match. In The King of Fighters 2003 and XI, Yuri continues in the Art of Fighting Team, but only with Ryo and Robert as the tournament once again requires only 3 fighters per team. Yuri's next official King of Fighters appearance was in The King of Fighters XIII, where she joins her fellow team members from The King of Fighters '94. However, by The King of Fighters XIV, Takuma fell ill as he had to not only manage the dojo but also his restaurant named "Kyokugen BBQ", thus prompting Yuri to not only leaving her '94 team members for her '96 team members Ryo and Robert, also to surpass her family.
