What is Wahhabism? Where does it have the most influence?

The influence of Wahhabism is much stronger in south India than in the north. Groups such as the Popular Front of India (PFI) and its political front, the Social Democratic Party of India, have gained considerable influence in Kerala and coastal Karnataka.

Explanation:

Wahhabism is an Islamic doctrine and religious movement founded by Muhammad ibn Abd al-Wahhab. It has been variously described as "ultraconservative", "far-right" "austere", "fundamentalist", or "puritan (ical) "; as an Islamic "reform movement" to restore "pure monotheistic worship" by devotees; and as a "deviant sectarian movement", "vile sect" and a distortion of Islam by its detractors
