History of vegetarianism
The history of vegetarianism has its roots in the civilizations of ancient India and ancient Greece. Vegetarianism is the theory and practice of voluntary non-consumption of the flesh of any animal (including sea animals), with or without also eschewing other animal derivatives (such as dairy products or eggs). The earliest records of vegetarianism as a concept and practice amongst a significant number of people concern ancient India and the ancient Greek civilizations in southern Italy and Greece. In both instances the diet was closely connected with the idea of nonviolence toward animals (called ahimsa in India), and was promoted by religious groups and philosophers.
