Other sections of society included the nobility, clergy, and townsmen. Nobles, both the titled nobility and simple knights, exploited the manors and the peasants, although they did not own lands outright but were granted rights to the income from a manor or other lands by an overlord through the system of feudalism. During the 11th and 12th centuries, these lands, or fiefs, came to be considered hereditary, and in most areas they were no longer divisible between all the heirs as had been the case in the early medieval period. Instead, most fiefs and lands went to the eldest son.[R] The dominance of the nobility was built upon its control of the land, its military service as heavy cavalry, control of castles, and various immunities from taxes or other impositions.[S] Castles, initially in wood but later in stone, began to be constructed in the 9th and 10th centuries in response to the disorder of the time, and provided protection from invaders as well as allowing lords defence from rivals. Control of castles allowed the nobles to defy kings or other overlords. Nobles were stratified; kings and the highest-ranking nobility controlled large numbers of commoners and large tracts of land, as well as other nobles. Beneath them, lesser nobles had authority over smaller areas of land and fewer people. Knights were the lowest level of nobility; they controlled but did not own land, and had to serve other nobles.[T]
In what century were castles first built?
9th

In his work "On the Jews and Their Lies" (1543), German Reformation leader Martin Luther claims that Jewish history was "assailed by much heresy", and that Christ the logos swept away the Jewish heresy and goes on to do so, "as it still does daily before our eyes." He stigmatizes Jewish Prayer as being "blasphemous" (sic) and a lie, and vilifies Jews in general as being spiritually "blind" and "surely possessed by all devils." Luther calls the members of the Orthodox Catholic Church "papists" and heretics, and has a special spiritual problem with Jewish circumcision.
What is said to be a special spiritual problem?
Jewish circumcision

Everton's biggest rivalry is with neighbours Liverpool, against whom they contest the Merseyside derby. The Merseyside derby is usually a sellout fixture, and has been known as the "friendly derby" because both sets of fans can often be seen side by side red and blue inside the stadium both at Anfield and Goodison Park. Recently on the field, matches tend to be extremely stormy affairs; the derby has had more red cards than any other fixture in Premiership history. The rivalry stems from an internal dispute between Everton officials and the owners of Anfield, which was then Everton's home ground, resulting in Everton moving to Goodison Park, and the subsequent formation of Liverpool F.C., in 1892.
In what year was the Liverpool Football Club established?
1892
