The Anglo-Saxon capitalism originates from growth and development of Anglo-Saxon economy in eleventh century.[13] The growth can be partially explained by England's fertile and accessible land, rich fisheries and mineral deposits.[14] However, people would not have been able to exploit these resources so successfully if there had not have been fundamental changes in English institutions between the eighth and eleventh centuries.[14] The older system of bartering was replaced by the newer system where commodities were exchanged for money.
