Roman Law: A Historical Overview of Key Periods and Legal Sources
Early Classical Period (130 BC – 30 BC)
This era is marked by the contrast between Auctoritas (socially recognized knowledge) and Potestas (formal power). Key legal sources include:
Jurisprudence
Based on Auctoritas, lawyers engaged in three main activities:
- Respondere: Providing legal opinions and interpretations to magistrates, judges, and individuals.
- Cavere: Advising individuals on drafting contracts and legal documents to prevent future disputes.
- Agere: Assisting individuals in legal proceedings and court actions.
Law
Laws were categorized as either Lex Publica (public law) or Lex Privata (private law). The process of enacting Lex Publica involved:
- Rogatio: A magistrate proposes a law to the public assembly.
- Iussum Populi: The public assembly approves the law.
- Publication: The law is publicly displayed and takes effect.
Leges rogatae (laws passed by the assembly) had specific components:
- Heading with the proposing magistrate’s name.
- Exposition of the law’s content.
- Praescriptio (preamble).
- Rogatio (main body of the law).
- Sanctio (provisions regarding the law’s validity and enforcement).
- Clause nullifying actions contrary to the law and previous conflicting laws.
Edict of the Praetor
The Praetor’s edict outlined the available legal actions, exceptions, and procedures within their jurisdiction. Edicts could be perpetual (lasting throughout the Praetor’s term) or temporary.
Central Classical Period (30 BC – 130 AD)
During this period, the role of the emperor and the Senate in lawmaking increased. Key developments include:
- Augustus established the ius respondendi, granting certain jurists the authority to issue official legal opinions.
- The role of popular assemblies in lawmaking declined, with the Senate taking on a more prominent role.
- Emperor Hadrian codified the Praetor’s edict into the Edictum Perpetuum, limiting further modifications.
Legal literature flourished, with works such as responsa (case studies), quaestiones (legal treatises), digesta (collections of legal opinions), and commentaries on specific laws or topics.
Late Classical Period (130 AD – 230 AD)
This era saw the rise of imperial officials in legal matters and a shift towards summarizing and commenting on existing legal works. Notable jurists include:
- Pomponius
- Gaius (known for his Institutes)
- Papinian
- Ulpian
- Paul
Rescripta Imperiales: Emperors issued written responses to legal questions, known as rescripts, which held legal authority.
Senatusconsulta: While the Senate’s legislative power diminished, it still issued decrees known as senatusconsulta.
Post-Classical Period (230 AD onwards)
The legal system underwent significant changes, with imperial pronouncements becoming the primary source of law. Key figures and developments include:
- Diocletian: Implemented the Tetrarchy system and established a more centralized imperial administration.
- Constantine: Reintroduced the concept of leges (imperial laws) as the primary source of law.
- Theodosius II: Commissioned the Codex Theodosianus, a compilation of imperial laws.
Legal works during this period often focused on summarizing and simplifying existing legal materials, leading to a trend of legal vulgarism.
Important legal compilations include:
- Pauli Sententiae
- Epitome Gai
- Ulpiani Epitome
- Fragmenta Vaticana
- Collatio Legum Mosaicarum et Romanarum
- Consultatio Veteris Cuiusdam Iurisconsulti
- Lex Romana Visigothorum (Breviary of Alaric)
The culmination of Roman legal development is the Corpus Iuris Civilis, compiled under Emperor Justinian in the 6th century AD, which remains a foundational legal text in many legal systems today.
