When a person is ready to use violence to defend extreme political or religious ideas, we say they become “radical”.

For example, in October 2020, a radicalized Muslim killed Samuel Paty, a teacher, to impose an extreme vision of his religion, Islam.

Another example: in 2019, a radicalized man, who was promoting extreme far-right ideas, attacked mosques in Christchurch, New Zealand.

But why do people become radical?

Radicalization doesn’t happen overnight, but bit by bit.
