Overview Timeline


First Century

  • c. 56 - Túathal Techtmar, a local Irish prince is expelled from Ireland and goes into exile in Scotland.
  • c. 74 - A settlement is founded on Lambay Island by refugees from Burgantia, fleeing the Romans in Britain. This settlement, over time, grows into a successful trading post.
  • 81 - C. Julius Agricola, Governor of Britannia, launches an expedition across the Irish Sea to scout areas known only to Roman traders.
    • A fort at Drumanagh, a headland several miles north of OTL Dublin is established as a military beachhead and to protect a local trade post with Irish merchants.
  • 82 - Irish attack on the Romans in Drumanagh. The fort survives, but is heavily damaged. This prompts Agricola to invade Ireland instead of Caledonia as he did in OTL.
  • 83 - Agricola amasses a fleet and returns to Ireland instead of launching an invasion of Caledonia. The XX Valeria Victrix under his command, supported by a large number of British auxiliaries, lands near Drumanagh. The Romans number at least 8000 auxiliaries, including four cohorts of Batavians and two cohorts of Tungrian swordsmen, 3000 cavalry, and 17,000 to 30,000 overall.
    • With support from the Romans, Túathal Techtmar, son of High King Fíachu Finnolach, begins raising Irish auxiliaries to join him in his cause.
    • The Romans advance south, defeating the Eblani tribe in battle south of the river Bolinna (subject to change), named from the Irish word Bhóinn.
    • The city of Eblana near modern day Dublin, named by the Romans based on the neighboring tribe, is captured and raided.
    • A second tribe is encountered south of Eblana, known as the Cauci.
  • 83 - Agricola is recalled from Britain by Domitian.
  • 87 - Domitian launches an invasion of Dacia. The praetorian prefect Cornelius Fuscus crosses the Danube into Dacia with five or six legions on a bridge built on boats, but is ambushed and defeated at the First Battle of Tapae by the Dacian leader Diurpaneus, who was subsequently renamed Decebalus and was chosen to be the new king.
  • 88 - Under the command of Tettius Julianus the Romans defeat the Dacians at the outlying Dacian fortress of Sarmizegetusa. After this battle Decebalus, now the king of the four reunited arms of the Dacians, asks for peace but is again refused. Domitian later accepts the offer, in order to move his legions to the Rhine, against the revolt of Lucius Antonius Saturninus, the Roman governor of Germania Superior, who had allied with the Marcomanni, Quadi and Sarmatian Yazgulyams against Domitian.
  • 89 - Decebalus becomes a client king of the Romans, but instead uses Roman funds and aid to construct defenses against the Romans.
  • 93 - Agricola dies on his family estates in Gallia Narbonensis aged fifty-three.
  • 96 - Emperor Domitian is assassinated in a palace conspiracy organized by court officials.
    • That same day the Senate proclaims M. Cocceius Nerva emperor. The hasty ascension is due largely in part to the Senate’s hope of preventing civil war.
    • Damnatio Memoriae is passed by the Senate on Domitian’s memory. His coins and statues are melted, his arches are torn down, and his name is erased from all public records.
    • The people of Rome are largely indifferent to the news of Domitian’s death, however rioting breaks out among the army. The Praetorian Guard demands the execution of Domitian’s assassins, which Nerva refuses.
  • 97 - The Praetorian Guard, led by Casperius Aelianus, lays siege to the Imperial Palace and takes Nerva hostage. He is forced to submit to their demands, agreeing to hand over those responsible for Domitian's death and gives a speech thanking the rebellious Praetorians.
  • 98 - Nerva announces his adoption of M. Ulpius Traianus as his successor, before all but abdicating. Trajan is officially bestowed the title of Caesar, and shares the consulship with Nerva that year. Before he can take his place in this capacity, Nerva dies.

Second Century

  • 101 - Trajan launches an invasion of Dacia, in an effort to relieve the economic difficulties brought on by previous military campaigns, replenish the gold supply following Nero’s spending, and secure other valuable resources, such as copper and iron. Trajan’s advance is successful and he defeats the Dacians decisively at the Second Battle of Tapae. Trajan makes peace with the Dacians, establishing an allied zone that can defend against attacks from further north and east.
  • 105 - Trajan launches a second war into Dacia after the Roman client Decebalus begins inciting rebellion among tribes of the Danube, and raiding Roman colonies in the region.
  • 106 - Legions II Adiutrix and IV Flavia Felix, supported by a detachment vexillatio from VI Ferrata, surround the Dacian capital of Sarmizegetusa after gradually capturing the kingdom’s mountainous fortresses.
  • 107 - Trajan devalues the Roman currency, by decreasing the silver purity of the denarius from 93.5% to 89%, with the actual silver weight dropping from 3.04 grams to 2.88 grams. This devaluation, coupled with the massive amount of gold and silver carried off after Trajan's Dacian Wars, allows the emperor to mint a larger quantity of denarii. He also withdraws from circulation silver denarii minted before the previous devaluation by Nero, allowing him to increase civil and military spending.
