Examples of Cornish Stone Age, Bronze Age and Iron Age structures are Chûn Quoit, Boscawen-Un and Chysauster Ancient Village. First Cornish hedges.

2000 BC

Mining in Cornwall has existed from the early Bronze Age around 2150 BC and it is thought that Cornwall was visited by metal traders from the eastern Mediterranean. It has been suggested that the Cassiterides or "Tin Islands" as recorded by Herodotus in 445 BC may have referred to the Scilly Islands and Cornwall as when first discovered they were both thought to have been islands.

1600 BC

Cornwall experiences a trade boom driven by the export of tin across Europe.

750 BC

The Iron Age reaches Cornwall, permitting greater scope of agriculture through the use of new iron ploughs and axes.

330 BC

Pytheas of Massilia (now Marseilles), a Greek merchant and explorer, circumnavigated the British Isles between about 330 and 320 BC and produced the first written record of the islands. He described the Cornish as civilised, skilled farmers, usually peaceable, but formidable in war.

100 BC

60 BC: Greek historian Diodorus Siculus named Cornwall "Belerion" – "The Shining Land", the first recorded place name in the British Isles.
55 BC: First attempted invasion of British mainland by Julius Caesar. Over the next century, the Romans come to rule Cornwall, then part of Dumnonia.

1st millennium

Roman invasion and occupation

The Roman inscribed stone at Trethevy (251–253 AD)

19 AD: Total eclipse in Cornwall.
43 AD: Claudian invasion of Britain begins. Roman control of Cornwall comes much later, but at an uncertain date.
55–60 AD: Construction of Nanstallon Roman fort near Bodmin, one of only a few Roman sites in Cornwall.
Roman villa at Magor Farm near Camborne occupied.
360 and after: various Germanic peoples came to Roman Britain: raiders, Roman armies recruited from among German tribes, authorized settlers: ref. Ælle of Sussex

5th century

"King Mark of Cornwall", illustrated by Howard Pyle (1905)

Cornwall's native name (Kernow) appeared on record as early as 400. The Ravenna Cosmography, compiled c. 700 from Roman material 300 years older, lists a route running westward into Cornwall and on this route is a place then called Durocornovio (Latinised from British Celtic duno-Cornouio-n – "fortress of the Cornish people"). In Latin, 'V' represented and was pronounced as a 'W' and the fortress name refers to Tintagel.
410: Emperor Honorius recalls the last legions from Britain. There is some uncertainty: some say that this "rescript" refers not to Britannia (= Britain) but to Bruttium in Italy.
Mid-5th century: first waves of settlers from Cornwall, and Devon, go to Brittany
433: The Britons call the Angles to come and help them (as mercenaries) against the Picts.
about 446: The "Groans of the Britons" last appeal (possibly to the Consul Aetius) for the Roman army to come back to Britain.
King Mark, of Tristan and Iseult fame, probably ruled in the late 5th century. According to Cornish folklore, he held court at Tintagel. King Salomon, father of Saint Cybi, ruled after Mark.

6th century

500: The Kingdom of Cornwall emerged around the 6th century which included the tribes of the Dumnonii and the Cornish Cornovii. The origins of the neighbouring Kingdom of Wessex are also in this period.
490 to 510: likely range of dates for the Battle of Mons Badonicus, in which Romano-British Celts defeated an invading Anglo-Saxon army.
535/6: Extreme weather events of 535–536 cause European famine.
After 540s : Plague of Justinian, which would affect all of Europe.
577: Battle of Deorham Down near Bristol results in the separation of the West Welsh (the Cornish) from the Welsh by the advance of the Saxons. The earliest Cornish saints systematically convert Cornwall to Christianity, a considerable period before the conversion of the Anglo-Saxon peoples of England (the territory east of the River Tamar). According to tradition these early monastic foundations were made by Christian preachers or Christian Druids from other Celtic lands, mainly Ireland (as in the cases of Saint Piran and Saint Gwinear), Wales (as in the case of Saint Petroc and the Children of Brychan), and Brittany (as in the case of Saint Mylor).

7th century

658 Battle of Peonnum drives the Britons from the area around Glastonbury abbey down to the River Parret.
664: The Synod of Whitby determines that England is again an ecclesiastical province of Rome, with its formal structure of dioceses and parishes. The Celtic Church in Dumnonia is not party to the decision and the Cornish Church remains monastic in nature.
682: Centwine, King of Wessex drove the Britons of the West at the sword's point as far as the sea. (ASC) Difficult to place due to the nature of the South-West as a Peninsula but likely to be the North Coast around Bridgewater in Somerset as the border had been set at the River Parret by the Battle of Peonnum

8th century

710: Battle of Llongborth (probably Langport in Somerset) fought to try to prevent further English expansion into Devon.King Geraint of Cornwall's led the fighting and his death is recorded in the Elegy for Geraint in the Black Book of Carmarthen. Tensions possibly exacerbated by Geraint's refusal to allow the Celtic church to follow the call of the English church (which was perhaps 300 years younger) to conform to the standards of Rome. The battle was fought against the West Saxon King Ine and his kinsman, Nonna.
722: Battle of Hehil – The Cornish Britons together with their friends and allies, push back a West-Saxon offensive at "Hehil", unlocated, but probably somewhere in modern Devon.
753 Cuthred of Wessex fights 'Against the Welsh (Cornish)' according to the Anglo-Saxon Chronicle
755 Cynewulf fights 'Hard battles against the Welsh (Cornish)'

9th century

807: Unsuccessful Cornish alliance with Danes.
815: The Anglo Saxon Chronicle states "& þy geare gehergade Ecgbryht cyning on West Walas from easteweardum oþ westewearde."...and in this year king Ecgbryht harried the Cornish from east to west.

The Doniert Stone which may refer to King Dungarth

825: The Battle of Gafulforda, at an uncertain location, thought to be Galford, near Lewdown in West Devon. The Anglo Saxon Chronicle only states: "The Wealas (Cornish) and the Defnas (men of Devon) fought at Gafalforda".
838: Battle of Hingston Down: the Anglo-Saxon Chronicle reports that the Cornish in alliance with the Danes were defeated by Egbert of Wessex at "Hengestesdun", generally considered to be Hingston Down in eastern Cornwall.
850: Settlement at Mawgan Porth occupied. Archaeological excavations revealed a settlement comprising three groups of buildings ('courtyard houses') and a burial ground dating from around 850–1050. Finds included pottery and stone artefacts.
875: King Dungarth (Donyarth) of Cerniu ("id est Cornubiae") drowns in what is thought to be the River Fowey.
880s: the Church in Cornwall is having more Saxon priests appointed to it and they control some church estates like Polltun, Caellwic and Landwithan (Pawton, in St Breock; perhaps Celliwig (Kellywick in Egloshayle?); and Lawhitton). Eventually they passed these over to Wessex kings. However, according to Alfred the Great's will the amount of land he owned in Cornwall was very small.
late 9th century: The earliest known example of written Cornish is a gloss in a late 9th century Latin manuscript of De Consolatione Philosophiae by Boethius, which used the words ud rocashaas. The phrase means "it (the mind) hated the gloomy places".

10th century

Olaf Tryggvason, who supposedly visited the Isles of Scilly in 986. It is said an encounter with a cleric there led him to Christianise Norway.

926: The entry in the Anglo-Saxon Chronicle reads....'This year fiery lights appeared in the north part of the heavens. And Sihtric perished: and king Aethelstan obtained the kingdom of the North-humbrians. And he ruled all the kings who were in this island: first, Huwal king of the West-Welsh (Cornish or Deheubarth); and Constantine king of the Scots; and Uwen king of the people of Guent; and Ealdred, son of Ealdulf, of Bambrough: and they confirmed the peace by pledge, and by oaths, at the place which is called Eamot, on the 4th of the ides of July [12 July]; and they renounced all idolatry, and after that submitted to him in peace.
927: William of Malmesbury, writing around 1120, says that Athelstan evicted the Cornish from Exeter and perhaps the rest of Devon: "Exeter was cleansed of its defilement by wiping out that filthy race". The area inside the city walls still known today as 'Little Britain' is the quarter where most of the Cornish Romano-British aristocracy had their town houses, from which the Cornish were expelled. Under Athelstan's statutes it eventually became unlawful for any Cornishman to own land, and lawful for any Englishman to kill any Cornishman (or woman or child).
928: It is thought that the King Huwal, "King of the West Welsh" (Cornwall or Hywel Dda of Deheubarth) was one of several kings who signed a treaty with Aethelstan of Wessex at Egmont Bridge.
930: Armes Prydein, (the Prophecy of Britain), this early Welsh poem mentions 'Cornyw', the Celtic name for Cornwall. It foretells that the Welsh together with Cornwall, Brittany, Ireland and Cumbria would expel the English from Britain. This poem also demonstrates any early allegiance between the Celtic people of Britain.
936: Athelstan fixed Cornwall's eastern boundary as the east bank of the Tamar. There is no record of Athelstan taking his campaigns into Cornwall and it seems probable that Huwal, King of the Cornish, agreed to pay tribute thus avoiding further attacks and maintaining a high degree of autonomy. Prior to this the West Saxons had pushed their frontier across the Tamar as far west as the River Lynher, but this was only temporary. It was long enough, however, for Saxon settlement and land charters to influence our modern day inheritance of placenames: between Lynher and Tamar there are today many more English than Cornish place names, as is also the case in that other debatable land between Ottery and Tamar in north Cornwall.
944: Athelstan's successor, Edmund I of England, styled himself "King of the English and ruler of this province of the Britons"
981: The Vikings lay waste "Petroces stow" (probably Padstow) according to the Anglo-Saxon Chronicle.
986: Olaf Tryggvason allegedly visits the Isles of Scilly
997: The Dartmoor town of Lydford, near the Cornish/Wessex border just east of the Tamar is completely destroyed by an angry mob of Danish Vikings. The surprise attack on Lydford is ordered by the King of Denmark and Viking leader Sweyn Forkbeard (previously, Lydford was believed to be impregnable against Viking attack). However, Cornwall is left alone as Sweyn Forkbeard has no intention of crushing Cornwall—unlike Wessex.

2nd millennium

11th century

1013: Cornwall's enemy and Anglo-Saxon neighbour, Wessex is crushed and conquered by a Danish army under the leadership of the Viking leader and King of Denmark Sweyn Forkbeard. Sweyn annexes Wessex to his Viking empire which includes Denmark and Norway. He does not, however, annex Cornwall, Wales and Scotland, allowing these "client nations" self-rule in return for an annual payment of tribute or "danegeld".

Subsequently, for Launceston, Reginald's Charter continues that distinction – "To all my men, French, English and Cornish".
1198: William de Wrotham (Lord Warden of the Stannaries) writes of those working tin in Cornwall paying twice the taxation of their Devon counterparts.

1642: The Cornish play a significant role Civil War as Cornwall was a Royalist stronghold in the generally Parliamentarian south-west.
