Before Partition in 1947, the Punjab used to cover part of Pakistan and present-day Punjab, with Lahore as the capital. Lahore is now the capital of the Punjab state in Pakistan. The main city in the Punjab is Amritsar, the holy city of the Sikhs. The main reason why most people come to Punjab is to see the Golden Temple in Amritsar. I have yet to meet anyone who did not enjoy their trip there.
Some major battles were fought in Punjab, which helped shape the destiny of India. For years, Muslim invaders entered India through Punjab.
In the past there has been tension in Punjab. Sikh militants have wanted to form an independent Sikh nation called Khalistan. In 1983, Jarnail Singh Bhindranwale, the Sikh militant leader, shut himself up in the Golden Temple in Amritsar and the violence in Punjab increased.
