The Middle Ages can also be considered the Medieval period. Many include William the Conqueror's invasion of England in 1066 as a beginning point for this age. This period usually ends in the late 1400s. During this period there were many changes taking place, such as: the English Reformation, the emergence of a subtle middle class, and, of course, wars. At this time period, there were three classes in society in England and they were the Clergy, the Nobility, and the working class. As Chaucer, Spenser and other writers rejected French and wrote in English, the common man's language started to emerge. Most nobility spoke in French because it was the language of the King's Court, but as English began to establish its literary roots, it also began to grow and to become more popular and more widely used. The next step for the working class to threaten the nobility would be if they learned to read and write in English because this would promote more education and learning among the masses. More education means that laborers gain more opinions to what they deserve in life and that would concern any nobleman seeking to maintain control over his workers and land.
