The system of cooperation known as Feudalism ended around the 15th century is the true statement.
Feudalism flourished in Medieval Europe between the 9th and 15th centuries. This system of cooperation was a combination of legal and military customs. Though the 13th century is evident for the weaknesses of the system yet the system remains a central theme in Europe until the 15th century. There were many factors which caused the decline of Feudalism such as Black Death, nobles became weaker and peasant revolts etc. the decline of Feudalism, therefore,resulted in the Establishment of Central Government.
