India is well-known for its tradition of vegetarianism which has a history spanning more than two millenia. However, this was not always the case. During the Vedic period (1500-500 BC), the priestly castes sacrificed animals to appease and gain boons from the gods, after which the flesh was consumed. But the trend of meat-eating shifted with the times. The anti-meat eating sentiment was already felt at the end of the Vedic period. This period also saw the rise of Buddhisln and Jainism, the founders of which abhorred the practice of sacrificing and consuming the flesh of animals, preaching the principle of ahimsa or ''non-harming''. To win back these converts into their fold, the Hindu priests advocated against killing, their public appeal beginning around the Ist century BC. They embraced ahimsa and followed a vegetarian diet, regarding it as superior to the Brahminical ideas of sacrifice. Advocating this new doctrine, however, did not meet with great opposition from meat lovers as there had already been a religious attitude towards animals since Vedic times. In fact, only the meat of a sacrificed animal was considered food. Among the animals that were sacrificed in Vedic times was the cow, which is virtually deified in the Hinduism of today. In the Atharvaveda, beef-eating was prohibited as it was likened to committing a sin against one's ancestors. But at the beginning of the Epic period (c.l000- 800 BC), this meat was said to be common food that added vigour not only to the body but also to the mind. The tables were turned in the 5th century BC in favour of the cow. When it was discovered at this time that the cattle population was decreasing at an alarming rate, people began to realise that a live cow was a greater asset than its carcass. Since ghee (clarified butter), milk and yoghurt were vital for temple rituals, this animal began to enjoy a greater prominence and thus, its flesh became a prohibited meat. This was the start of the taboo of eating beef which has become a long-standing feature in Hinduism. But vegetarianism goes one step further than the avoidance of beef. Throughout India's history, there are occurrences of vegetarianism being practised. For example, there is evidence that in 800 BC, people began to eat more vegetables, pulses, cereals and fruit, as a consequence of the growing distaste for meat. Even the priestly castes of some areas that took to vegetarianism began to offer vegetarian foods to the gods. That kings such as Ashoka (c. 322-183 13C) forbade the killing of animals further contributed to the development of vegetarianism.
