The Martyrs of Córdoba were forty-eight Christian martyrs who were executed under the rule of Muslim administration in Al-Andalus (name of the Iberian Peninsula under the Islamic rule).[1][2][3] The hagiographical treatise written by the Iberian Christian and Latinist scholar Eulogius of Córdoba describes in detail the executions of the martyrs for capital violations of Islamic law (sharīʿa), including apostasy and blasphemy.[1][2][3] The martyrdoms recorded by Eulogius (the only contemporary source) took place between 850 and 859 AD,[4] which according to the Mālikī judges of al-Andalus broke the treaty signed between Muslims and their Christian subjects.
