At Agincourt, Henry V fought to reclaim what he believed belonged to his inheritance: the Duchy of Normandy. A chef must think like a scientist shirt. It was in the hands of the British more than 200 years before the French king took it from King John, his vassals. The intense confrontation between England and France began in 1066, when the Duke of Normandy conquered England. But the Normandy dignity was always the vassal of France, so even though William became King of England, William did not change this relationship. In the middle of the 12th century, the British king Norman was replaced by another dynasty, the Anjou court, who possessed vast lands in western and southwestern France.
