He threw the money changers out of the Temple, which annoyed the Sanhedrin. This led to him being stoned to death on the eve of Passover. He was *not* crucified, Passover is at the Vernal Equinox, the old pagan festival whose symbol is a cross, to indicate the crossing of Winter into Spring. So Jesus died 'on the cross', but he was in fact stoned to death by his own people, no Roman involvement whatever.
