Explanation:

The First Battle of Anandpur 1701 A.D. : After two years of the creation of the Khalsa, Guru Gobind Singh Ji had to declare war against the Kings of hill states. The main cause of this battle was that the kings of hill states became nervous by the creation of the Khalsa. The principles of the Khalsa were also against the religion of the Kings of hill states. So Bhim Chand the ruler of Bilaspur asked Guru Sahib to either have Anandpur Sahib or pay appropriate rent for it. Guru Sahib rejected his demand. As a result, in 1701 A.D. armies of Bhim Chand and other Kings of hill states besieged Anandpur Sahib. Guru Sahib, Sahibzada Ajit Singh (14-15 years old) and other Sikhs made the enemies suffer a great loss. As a result, the disappointed Kings of hill states wanted to enter into an agreement with Guruji. Guruji who also did not want to fight with them made the agreement. According to the agreement, Guruji left Anandpur Sahib and went to stay at Nirmoh near Kiratpur Sahib.
