Antiquity

c. 325 BCE – Pytheas of Massalia (Marseilles) becomes the first to mention the "Pretanic Isles" by name; he refers to the island of Great Britain as “Albion” and Ireland as “Ierne”.

58 BCE–51 BCE – The Gallic Wars of Julius Caesar, during which he not only conquers all of Gaul, but also invades Britannia and Germania.

55 BCE – Caesar’s first invasion of Britain. At this time, Ireland is divided into five provinces, or coicids: Midhe, Ulaidh, Ol-nEchtmachta, Laighin, and Mumhan.

52 BCE – The Gauls rise up against Roman occupation under Vercingetorix.

43 CE – Beginning of the Roman conquest of Britain, under Claudius.

60 CE – The revolt of the Britons led by the Iceni queen Boudica begins. Three Roman towns are entirely destroyed and 50,000 colonists killed, nearly convincing Nero to abandon Britain, but Boudica’s army is annihilated at the Battle of Watling Street the following year.

80 CE – Agricola reaches the River Tay and begins building a fortress at Inchtuil which he plans to be the largest in the Roman Empire, and other fortifications north of the Forth and Clyde, but construction soon halts and the sites are abandoned.

122-157 – Reign of Conn Cétchathach (of the Hundred Battles) as High King of Ireland.

122-128 – Hadrian's Wall is built from the mouth of the River Tyne to the Solway Firth, originally anchored in the east by Pons Aelius (Newcastle-upon-Tyne) and in the west by Luguvalium (Carlisle), until it is extended to the fort of Segedunum (Wallsend) in the east and the fort of Mais (Bowness-on-Solway) in the west. A total of twenty-five forts in all support the Wall.

142-144 – The Antonine Wall is built between the Firth of Forth and the Firth of Clyde, with eleven forts along its length.

164 – The Romans abandon the Antonine Wall and fall back to Hadrian’s Wall.

270 – About this time, the system of forts late known as the Saxon Shore start being built, based on the system of forts supporting the Classis Britannica (the coastal patrol), at first in defense against the Frisians, for whom the North Sea is at the time called Mare Frisia.

274 – The Gallic Empire is reunited with the Roman Empire.

285 – Diocletian divides the Empire into Eastern and Western halves under himself, in the east, and Maximian, in the west as Augusti.

Constantius Chlorus is appointed as Caesar over Gallia, Britannia, and Hispania by Maximian. In a letter to his superior, Constantius mentions raiding by the Frisians along the eastern coasts of Britain.

294 – Carausius is murdered by his treasurer, Allectus, who takes his place.

297 - Allectus is defeated in battle and killed by the Roman army and his dominions are reunited with the Empire. Caesar Constantius divides Britannia Superior into Maxima Caesariensis and Britannia Prima, and Britannia Inferior into Britannia Secunda and Flavia Caesariensis, making it a diocese headed by a vicarius, under the Prefecture of Gaul.

305 – Reportedly about this time a group of Deisi establishes a colony among the Demetae; a group of Laighin is granted land in Lleyn peninsula; and the Eoganachta are given lands in the later Ceredigion (under Lethan), Dumnonia (under Corpre), and Circinn in the north (under Fidig). The Ui Laithin have a colony in Dumnonia. A group of Ui Bairrche settle in Scotland. If true, most or all of these may be colonies of foederati.

It begins after The Roman garrisons along Hadrian’s Wall rebel; the northern and western areas of Britain are overwhelmed.

The so-called Great Conspiracy, and the incipient revolt from within, is finally defeated by a force under Comes Theodosius.

369 – An additional province, Valentia, is added in the north, probably in southern Scotland between the Walls, with its seat at Luguvalium (Carlisle).

His half-brothers Brion, Ailill, and Fiachrae, found dynasties in Ol-nEchtmachta, which takes their family name of Connachta.

382 – Third wave of raiding by Scots, Picts, and Saxons. Aed Brosc of the Deisi is brought over to help repel the raids. After their defeat, Magnus Maximus, the Magister Militum, assigns Roman generals, praefecti gentium, to commands in the north: Quintilius son of Clemens at Alt Clut, Paternus son of Tacitus at Din Paladur (Traprain Law), Catellius Decianus at Din Gefron (Yeavering Bell), Antonius Donatus Gregorius (son of Magnus Maximus) in Novant at first but later in Demetia in Wales. Ruling dynasties later trace their descent back to these praefect'.

383 to 388 – Revolt of Magnus Maximus. First wave of Briton colonists to Armorica.

The Portugese Inquistion begins and will last until 1821.

1541 – Henry VIII has himself declared King of Ireland by the Irish Parliament, and begins the Tudor reconquest of Ireland with the aim of Anglicizing its gentry. The “pacification” begins with an attempt to plant voluntary colonies of English around Ireland on land leased from landowners.

It is worth noting that prior to this, Catholic landlords in Ireland had already been importing tenants from these very same regions, and that many of those planted were Catholic as well as Protestant and Dissenter.

1613 – Through the creation of numerous Protestant-dominated burghs, the crown manages to overthrow the Catholic majority in the Irish parliament.

In reponse, the native Gaelic majority rises, massacring “settlers” in numbers which the latest estimates give as 4,000, with another 12,000 dying from starvation, exposure, and disease. In an attempt to regain control and halt the atrocities, the early leaders of the rebellion establish the Catholic Confederation of Ireland, composed of previously antagonistic native Gaelic and Hiberno-Norman or “Old English” populations. The Confederates fight as allies of the Royalists, but only in their own country, against English Parliamentarians and Scottish Covenanters sent by the government of Edinburgh, in the midst of internecine strife. Owen Roe O'Neill, son of Hugh, returns from Spain to take command of the Confederate armies, but dies of disease in 1649 not long after Oliver Cromwell lands with a huge army and undertakes the thorough reconquest of the country, accompanied by widespread atrocities condoned and encouraged by him, most notably the horrific massacre of the the Confederate defenders at Drogheda, in what are acknowledged as the most ruthless parts of the Wars.

1642-1646 - First English Civil War.
