The Decian persecution refers to a period of intense persecution of Christians that began in 249 AD under the Roman Emperor Decius. This campaign aimed to restore traditional Roman religious practices and required all citizens to perform a sacrifice to the Roman gods, effectively targeting Christians who refused to comply. During this time, many Christians faced imprisonment, torture, and execution for their beliefs. The persecution was notable for its systematic approach, as authorities sought to identify and punish Christians, leading to a significant impact on the early Christian community and its growth in the Roman Empire.
