During the inquisition, most notably the Spanish Inquisition, people who were not Christians (Jews and Muslims) had to convert under the penalty of death. Many were also expelled from Spain and other countries. There was no tolerance in that regard.
The people persecuted in the Spanish Inquisition were "New Christians", which is to say Jews and Muslims who converted to Christianity in order to continue living in Spain (since Judaism and Islam were banned), but who were believed to be secretly practicing their faith of birth. Hundreds of thousands of Jews and Muslims who converted to Christianity were persecuted. Later, the Spanish Inquisition also persecuted Protestant reformers.
