As anti-government protesters demonstrated in Timișoara in December 1989, he perceived the demonstrations as a political threat and ordered military forces to open fire on 17 December, causing many deaths and injuries. The revelation that Ceaușescu was responsible resulted in a massive spread of rioting and civil unrest across the country. The demonstrations, which reached Bucharest, became known as the Romanian Revolution—the only violent overthrow of a communist government in the course of the Revolutions of 1989. Ceaușescu and his wife Elena fled the capital in a helicopter, but they were captured by the military after the armed forces defected. After being tried and convicted of economic sabotage and genocide, they were immediately executed by firing squad on 25 December and Ceaușescu was succeeded as President by Ion Iliescu, who had played a major part in the revolution. Capital punishment was abolished shortly thereafter.
