March 18, c. 303
Nicomedia, Bithynia (now İzmit, Turkey)
10,000 Christians are beheaded
The exact date of the martyrdom of the Christians is unknown as it was over 1700 years ago and likely took place over a large span of time. However, the Roman Martyrology commemorates March 18 stating, “At Nicomedia ten thousand holy martyrs who were put to the sword for the confession of Christ.”
