summaryLong: A synod is a council of a Christian denomination, usually convened to decide an issue of doctrine, administration or application. The word synod comes from the Ancient Greek σύνοδος 'assembly, meeting'; the term is analogous with the Latin word concilium 'council'. Originally, synods were meetings of bishops, and the word is still used in that sense in Catholicism, Oriental Orthodoxy and Eastern Orthodoxy. In modern usage, the word often refers to the governing body of a particular church, whether its members are meeting or not. The term is also sometimes used to refer to a church that is governed by a synod.
lede: In 1059, Pope Nicholas II convened a synod in Rome that fundamentally changed how popes were elected, stripping away the influence of Roman aristocrats and establishing a formal college of cardinals as the sole electorate. This shift moved papal selection from street-level faction warfare to institutional process, and it stuck-the cardinal college still elects popes today.

impactStatement: "The 1059 synod established the cardinal college as the exclusive papal electorate, creating the framework that governs papal succession to this day. It was a deliberate institutional fix to chaos: before this, papal elections were routinely hijacked by Roman noble families and occasionally decided by mob violence. The decree formalized what had been ad-hoc practice and locked it into Church law."

consequences:
- title: Ecclesiastical Independence from Secular Authority

zeitgeistNote: The 1059 Synod of Rome occurred during the Cluniac Reform movement, which sought to purify the Church from corruption and secular interference. Europe was navigating the tension between temporal and ecclesiastical power following the fragmentation of Charlemagne's empire. The East-West Schism had occurred four years prior (1055), making papal authority and legitimate succession particularly urgent matters.
