Although all of the innovations mentioned above were important, the plow had the greatest potential for social and cultural change. It made more permanent cultivation possible in a greater variety of soils, and thereby led to the widespread replacement of horticulture by agriculture. It also facilitated the harnessing of animal energy which led to increased productivity. The plow and related techniques of agriculture apparently spread by diffusion until agrarian societies were eventually established throughout most of Europe, North Africa and Asia. The plow presupposed certain earlier inventions and discoveries underlying again the cumulative nature of technological change .In the earliest agrarian societies, religion was an extremely powerful force. Technological advance created the possibility of a surplus, but to transform that possibility into a reality required an ideology that motivated farmers to produce more than they needed to stay alive, and persuaded them to turn that surplus over to someone else.Although this has sometimes been accomplished by means of secular and political ideologies, a system of beliefs that defined peoples obligations with reference to the supernatural worked best in most societies of the past .
