The biggest way that Biryani was affected by the Indian Pakistan split was due to religion. Back in India, both vegetarian and meat Biryani were equally as important to the food culture. When Pakistan split from India, due to religious differences, it did not take with it the need for vegetarian Biryani. This is because in India, the majority of people at the time were Hindu, and in the Hindu religion, the diet is strictly vegetarian. Whereas, in Pakistan, the majority of people are obviously Muslim and they ate meat. Therefore in Pakistan, meat Biryani is much more popular than Vegetarian Biryani. This is probably why at some Pakistani restaurants, vegetarian Biryani is not even offered.
