Knighthood began in the 9th century. As a request of the fall of Charlemagnes Empire in Western Europe a new way of life began. Little kingdoms replaced the old Empire that were held together by kings or lords. Because of continuous attacks by invading Moors and Vikings , the greatest need in these new settlements was for protection and security. Therefore , a new form of civil government arose. Which was called feudalism based on mutual agreement between the kings and lords , and their knights or servants. The kings or lord gave land to his knight in exchange for the knights loyalty , service , and military protection.
