Sylvester III was briefly Pope during the huge mess that was caused by his predecessor,Pope Benedict IX. When the Romans grew sick of Benedict and his tawdry ways,they ran him out of town and quickly elected Giovanni de’ Crescenzi,the Bishop of Sabina,who took the name Sylvester III. Sylvester was by all accounts a very devout and holy man who didn’t even want to be the Pope,but he stepped up to the plate to try to help bring order to the chaos caused by Benedict. Unfortunately,Benedict didn’t stay gone long and returned with a force to reclaim his title. Sylvester was confined to a monastery and later on he was officially disposed by Holy Roman emperor Henry III. Due to the massive confusion caused by Benedict’s three separate terms as Holy Father(!),Sylvester was sometimes thought to be an anti-Pope but he’s still officially listed as a rightful Pope.
