Early Christians faced widespread persecution from the Roman Empire from around 100-313 AD. Christianity was illegal, and Christians who refused to worship Roman gods faced punishments such as imprisonment, exile, torture, and public execution. Prominent early Christian martyrs like St. Stephen, St. Agnes, and St. Cecilia were killed in gruesome ways for their faith. The Great Fire of Rome in 64 AD under Nero led to intense persecution of Christians, who were falsely blamed for starting the fire. Despite the risks of practicing Christianity while it was illegal, the new religion continued to grow due to its hopeful message and the powerful witness of martyrs who died for their beliefs.
