The conspiracy of Gaius Calpurnius Piso in 65 CE was a major turning point in the reign of the Roman emperor Nero (reign 54–68). The plot reflected the growing discontent among the ruling class of the Roman state with Nero's increasingly despotic leadership, and as a result is a significant event on the road toward his eventual suicide and the chaos of the Year of the Four Emperors which followed.^{[citation needed]}
