# Synod of Rome on Papal Elections

> Pope Nicholas II's decree established the papal conclave system, removing secular influence from papal elections and defining the Church's governance for nearly a millennium.

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.

## Summary

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.

## Key facts

- **Pope Who Convened It**: Nicholas II
- **Year**: 1059
- **Location**: Rome (Lateran)
- **Electoral Body Established**: College of Cardinals
- **Groups Previously Influential in Elections**: Roman aristocratic families (Orsini, Colonna, others)
- **Primary Reformer**: Cardinal Humbert of Silva Candida
- **Church Office Affected**: Bishop of Rome (Pope)

## Timeline

- **1046-01-01** - Three Competing Popes
  The papal schism of 1046 exposes the chaos of existing electoral procedures, with multiple claimants backed by different Roman factions.
- **1058-01-01** - Nicholas II Becomes Pope
  Nicholas II assumes office with a mandate to reform Church governance and reduce secular interference, particularly Roman aristocratic meddling in elections.
- **1059-04-13** - Synod Convened
  Pope Nicholas II convenes the Lateran Synod in Rome with the explicit goal of establishing a formal electoral process for papal succession.
- **1059-04-13** - Electoral Decree Issued
  The synod issues a decree stipulating that only cardinals shall elect the pope. The procedure reserves the right of other clergy and laity to 'assent' but strips them of voting power. Significantly, it limits the Holy Roman Emperor's traditional prerogative over papal confirmations.
- **1075-01-01** - Investiture Controversy Escalates
  The 1059 reform becomes fully tested during conflict between Pope Gregory VII and Emperor Henry IV, as the independent cardinal college proves capable of standing apart from imperial pressure.
- **1179-01-01** - Third Lateran Council Refines Process
  The Third Lateran Council (1179) formalizes cardinal voting further, requiring a two-thirds majority-a rule still in force for papal conclaves.

## Consequences

- **1059 - Ecclesiastical Independence from Secular Authority**: Pope Nicholas II's decree at the Synod of Rome established that cardinals, not emperors or kings, would elect popes. This directly challenged Holy Roman Emperor Henry IV's traditional influence over papal succession.
- **1076 - Investiture Controversy Escalation**: The electoral reforms of 1059 contributed to the broader conflict over church-state relations. Henry IV's attempted deposition of Pope Gregory VII in 1076 was partly a response to diminished imperial control over papal elections established in 1059.
- **1179 - Formalization of the College of Cardinals**: The Third Lateran Council under Pope Alexander III codified cardinal voting procedures initiated by the 1059 synod, requiring a two-thirds majority for papal election-a rule still in effect.
- **1294 - Schism Prevention Mechanisms**: Clement VI's establishment of the formal Papal Conclave process in 1294 (refined at Avignon) built directly on the 1059 framework, physically isolating electors to prevent external interference and rival claimants.
- **1917 - Modern Canon Law Codification**: The 1917 Code of Canon Law formally incorporated electoral principles originating from the 1059 synod into universal church law, establishing canonical requirements for all future papal elections.

## Then vs now

- **Papal election process formality**: 1059: Ad hoc, often influenced by secular rulers and Roman nobility → 2024: Codified by Canon Law; Cardinals only; Papal Conclave procedures - The 1059 synod under Pope Nicholas II established the first formal electoral process, eliminating lay influence
- **Number of cardinals eligible to vote**: 1059: Approximately 7-12 senior clergy → 2024: Up to 120 cardinals under age 80 - Modern conclave expanded significantly; John Paul II capped voting cardinals at 120 in 1996
- **Documented election procedures**: 1059: Oral tradition, no unified written rules → 2024: Apostolic Constitution Universi Dominici Gregis (2000) and successor documents
- **Secular ruler veto power**: 1059: Present; Holy Roman Emperor exercised significant influence → 2024: Abolished; Church exclusive authority - Nicholas II's synod explicitly prohibited lay investiture in papal elections

## Impact

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.
