Synonym discussion
Sense: noun/1
Zealot, fanatic, extremist, militant, and devotee all describe someone with strong beliefs, but they differ in intensity and scope. A zealot holds extreme views and actively tries to convert others, often with an aggressive or impatient tone. Fanatic suggests excessive, sometimes irrational enthusiasm that can apply to religion, politics, or hobbies ('a football fanatic'), and it can be used playfully. Extremist focuses on the content of the beliefs themselves — views far outside the mainstream, especially in politics ('a political extremist'). Militant implies a willingness to fight or take confrontational action for one's cause ('militant activist'). Devotee is the mildest of the group, simply describing a dedicated enthusiast without negative judgment ('a devotee of traditional jazz'). Unlike zealot, both fanatic and devotee can be neutral or affectionate in informal conversation.

Etymology
Zealot comes from the Greek word zēlōtēs (ζηλωτής), meaning 'an emulator' or 'a zealous follower', which in turn comes from zēlos (ζῆλος), meaning 'zeal, ardor, or jealousy'. The term entered English through Latin zelotes and later Old French zelote. The word is historically linked to the Zealots, a Jewish political movement in the 1st century AD that fiercely opposed Roman rule in Judea.
