The Church and the Gregorian Reform

In the tenth- and eleventh- centuries, the Church become under what is known as Lay Control.  Lay Control is when authority takes control over some business, agency, etc.  In this case, the local lords controlled the Church.  This led the Church to become a part in the feudal system.  Then all of this signals Pope Leo IX to take a stand and do something.  Later in the eleventh-century, we then see St. Gregory VII, whom the Gregorian Reform was named after, in a fight with the emperor of Germany, Henry IV.  And finally, Christendom and its meaning.
