The Sikhs become a Martial Sect ever since the death of Guru Har Krishan causing the Sikhs to lose trust in different communities.
Explanation:
Sikh communities came together during the period of Guru Har Krishans death and some coronation. With some sects of Sikhism they believe in an lineage of Gurus or believe in following a living guru. The main religions of the area at the time were Hinduism and Islam. The Sikh faith began around 1500 CE, when Guru Nanak began teaching a faith that was quite distinct from Hinduism and Islam. The different beliefs all happened because of a different teacher. I believe that the Sikhs began to hate the muslims because of their different beliefs.
