The Roman Empire

The first century was Rome's golden age.

  • Augustus (27 BC - 14 AD)
  • Tiberius (14-37 AD)
  • Caligula (37-41 AD)
  • Claudius (41-54 AD)
  • Nero (54-68 AD)
  • Galba, Otho, Vitellius (69 AD)
  • Vespasian (69-79 AD)
  • Titus (79-81 AD)
  • Domitian (81-96 AD)
  • Nerva (96-98 AD)

Rome's population: Approximately 1 million—the first city in history to reach this milestone.

Empire's population: 55-70 million people across three continents.

Christianity's Origins

The most historically consequential development of the first century:

  • Jesus's ministry (~27-30 AD)
  • Crucifixion (~30-33 AD)
  • Paul's conversion (~33-36 AD)
  • Paul's missionary journeys (45-67 AD)
  • Paul's letters (the earliest Christian writings)
  • Peter and Paul martyred in Rome (~64-67 AD)
  • Gospels written (~65-95 AD)

By century's end, Christianity had spread across the Mediterranean, with communities in Rome, Greece, Asia Minor, Egypt, and beyond.

The Jewish-Roman War (66-73 AD)

A pivotal conflict with lasting consequences:

  • Jewish revolt against Roman rule
  • Roman siege of Jerusalem (70 AD)
  • Destruction of the Second Temple
  • Mass casualties and displacement
  • Fall of Masada (73 AD)

This war fundamentally changed Judaism and accelerated Christianity's separation from its Jewish roots.

Pompeii and Vesuvius (79 AD)

  • Buried Pompeii and Herculaneum
  • Killed approximately 2,000 people
  • Preserved an entire Roman city
  • Provides unparalleled archaeological insight

Pliny the Younger's eyewitness account remains the earliest detailed description of a volcanic eruption.

Technology and Culture

  • Roman concrete perfected
  • Glass-blowing became widespread
  • Codex (book format) began replacing scrolls
  • Improved aqueduct and road engineering
  • Medical advances (Dioscorides' pharmacology)
  • Seneca's philosophical works
  • Pliny the Elder's Natural History
  • Josephus's historical writings
  • Earliest Christian texts
  • Tacitus and other historians

The Wider World

  • Han Dynasty China (contemporaneous major empire)
  • Parthian Empire (Rome's eastern rival)
  • Kushan Empire in Central Asia
  • Early kingdoms in sub-Saharan Africa

Trade connected Rome to China via the Silk Road, with Roman goods found as far as Vietnam.

Why It Matters

  • Christianity emerged to become the world's largest religion
  • Roman legal and political concepts influenced Western civilization
  • Latin evolved into Romance languages
  • Architectural and engineering innovations persisted for millennia
  • Historical records preserve this era in unusual detail
