Why might sikhism appeal to many indians during 1600s?

sikhism is a type of religion that believe in one God (monotheistic) and currently is the 9th largest religion in the world.
In the 1600s, A lot of indian territory  was conquered by Muslim emperor Jahangir and he violently tried to convert everyone to muslim religion. During this time, Sikhism people offer the people with peaceful and tolerate ways of defending themselves against the violence and amanged to win the favor of a lot of people in India

I think Sikhism appealed to many Indians in the past because it emphasized more on equality. Sikhist believed in one good and that people, regardless of their standing in the Indian caste system, regardless of gender, Muslim, Buddhist or Hindu, they are equal in the eyes of one god.
