This trend for the king to rely on his own men at the expense of the barons was exacerbated by the tradition of Angevin royal ira et malevolentia "anger and ill-will" and John's own personality. From Henry II onwards, ira et malevolentia had come to describe the right of the king to express his anger and displeasure at particular barons or clergy, building on the Norman concept of malevoncia royal ill-will. In the Norman period, suffering the king's ill-will meant difficulties in obtaining grants, honours or petitions; Henry II had infamously expressed his fury and ill-will towards Thomas Becket; this ultimately resulted in Becket's death. John now had the additional ability to "cripple his vassals" on a significant scale using his new economic and judicial measures, which made the threat of royal anger all the more serious.
John had to additional ability to do what?
cripple his vassals

War work again brought local prosperity during World War II, this time centered on Boeing aircraft. The war dispersed the city's numerous Japanese-American businessmen due to the Japanese American internment. After the war, the local economy dipped. It rose again with Boeing's growing dominance in the commercial airliner market. Seattle celebrated its restored prosperity and made a bid for world recognition with the Century 21 Exposition, the 1962 World's Fair. Another major local economic downturn was in the late 1960s and early 1970s, at a time when Boeing was heavily affected by the oil crises, loss of Government contracts, and costs and delays associated with the Boeing 747. Many people left the area to look for work elsewhere, and two local real estate agents put up a billboard reading "Will the last person leaving Seattle Turn out the lights."
During WWII what company added substantially to Seattle's economy?
Boeing aircraft

It was temporarily under the control of the Tibetan empire and Chinese from 650680 and then under the control of the Umayyads in 710. The Samanid Empire, 819 to 999, restored Persian control of the region and enlarged the cities of Samarkand and Bukhara (both cities are today part of Uzbekistan) which became the cultural centers of Iran and the region was known as Khorasan. The Kara-Khanid Khanate conquered Transoxania (which corresponds approximately with modern-day Uzbekistan, Tajikistan, southern Kyrgyzstan and southwest Kazakhstan) and ruled between 9991211. Their arrival in Transoxania signaled a definitive shift from Iranian to Turkic predominance in Central Asia, but gradually the Kara-khanids became assimilated into the Perso-Arab Muslim culture of the region.
Who conquered Tansaxania?
