The Normans and French who arrived after the conquest saw themselves as different from the English. They had close family and economic links to the Duchy of Normandy, spoke Norman French and had their own distinctive culture. For many years, to be English was to be associated with military failure and serfdom. During the 12th century, the divisions between the English and Normans began to dissolve as a result of intermarriage and cohabitation. By the end of the 12th century, and possibly as early as the 1150, contemporary commentators believed the two peoples to be blending, and the loss of the Duchy in 1204 reinforced this trend. The resulting society still prized wider French cultural values, however, and French remained the language of the court, business and international affairs, even if Parisians mocked the English for their poor pronunciation. By the 14th century, however, French was increasingly having to be formally taught, rather than being learnt naturally in the home, although the aristocracy would typically spend many years of their lives in France and remained entirely comfortable working in French.
