When did the Crisis of the Third Century begin?

The crisis of the third century began in 235 AD due to a series of complex factors that led to political instability, military conflicts, and economic hardships in the Roman Empire. The assassination of Emperor Alexander Severus marked the start of a turbulent period characterized by frequent changes in leadership, civil strife, and invasions from external forces. The crisis was fueled by internal power struggles, weak emperors, rampant corruption, economic decline, and military pressures. This tumultuous period lasted for several decades and significantly weakened the Roman Empire, laying the foundation for its eventual decline and fall.
