The 10th Sikh Guru was never able to go to Amritsar
Instead he built the city of Anandpur Sahib where he created a new community, new literature and raised four sons. This week Sikhs remember the murder of the 2 youngest sons as Mughals chased the Guru from Anandpur Sahib in 1704

Amritsar was under the control of Masands (hereditary ministers) who were appointed by earlier Gurus but often refused the leadership of their successors. Guru Tegh Bahadur, too, was refused entry to Amritsar by Masands who followed Prithi Chand older brother of Guru Arjan Dev

The 10th Guru focussed his attention on building a new city state in the foothills of the Sivalik mountains. From here, the Guru revolutionised the Sikh world with a court made up of poets and warriors. He punished the Masands and he prepared a new standing army - the Khalsa

His actions were strongly resisted by nearby Hindu nobility and their Mughal overlords who conspired to besiege him in Anandpur, and then chase him, after a series of running battles, 40km further south to Chamkaur.
The two eldest sons were killed in these battles

This week, Sikhs remember the capture and killings of the two youngest sons by the Mughal Nawab of Sirhind.
In a few short days the Guru suffered the loss of his four beloved sons, his mother, many of his most loyal men and many of the manuscripts and texts created by his court

Ultimately, embattled and betrayed but defiant, he escaped from the besieged fortress of Chamkaur to safety - under orders from his Khalsa to whom he was simultaneously Guru and servant.
