This timeline is incomplete

• 7000 BC - Mesolithic stone age inhabitants arrived some time after 8,000 BC.
• 4,500 BC - Agriculture followed with the Neolithic Age around 4,500 to 4,000 BC when sheep, goats, cattle and cereals were imported from the Iberian peninsula.

• 4500 BC - Neolithic agriculture and domestication of plant and animal life.
• 4000 BC - The great burial mounds soon begin to appear including the portal tombs and dolmens at Owning, Harristown and Borrismore, as well as the passage graves like those at Clomantagh Hill and Knockroe.
• 3500 BC - Neolithic single burial tombs known as Linkardstown Cists. One was excavated at Jerpoint West.

• 2500 BC - Bronze Age metal working, Ring-ditches, standing Stones, Cairns and Fulachta Fiadha. Standing stones include at Mount Misery, Ferrybank, and the three Friars at Smithstown. Stone circles present in other parts of Ireland are absent from Kilkenny.
• Nicroliths, polished-stone axes and early Bronze bowl cremation have been found.^[2]
• A late Bronze Age fishtrap was excavated from underneath St John's Bridge, Kilkenny.^[3]

• 600 to 500 BC - The Irish Iron Age begins.
• Goidelic-speaking Celts (from Spain? and elsewhere) possibly arrive in Ireland.
• 300 BC - Iron Age La Tene (Celtic) objects.
• 250 BC - The Laigin from Armorica in northwestern France are said to arrive in southeast Ireland. The term Laigin is an early name for Leinster.
• 100 BC - Hillforts and huge linear earthworks make their appearance sometime before or around this period. Earthworks on hilltops include Freestone Hill, Clomantagh Hill, Foulksrath and Cairndubh Hill.
• The Celtic tribes of Ireland include the Brigantes, a name which also belonged to the largest tribe of northern and midland Britain. Another tribe by the 2nd century AD was the Manapii, possibly the same people as the Menapii, a Belgic tribe of northern Gaul.
• Pottery and stone tools used by the first farmers and the remains of houses found in Granny and Newrath.

The ancient Osraige inhabited the fertile land around the River Nore valley, occupying nearly all of what is modern County Kilkenny and the western half of neighbouring County Laois. To the west and south, Osraige was bounded by the River Suir and what is now Waterford Harbour; to the east, the watershed of the River Barrow marked the boundary with Leinster (including Gowran); to the north, it extended into and beyond the Slieve Bloom Mountains. These three principal rivers- the Nore, the Barrow, and the Suir- which unite just north of Waterford City were collectively known as the "Three Sisters" (Irish: Cumar na dTrí Uisce).^[5] Like many other Irish kingdoms, the tribal name of Osraighe also came to be applied to the territory they occupied; thus, wherever the Osraige dwelt became known as Osraige.

• Ptolemy's 2nd-century map of Ireland places a tribe he called the "Usdaie" roughly in the same area that the Osraige occupied.^[6] The territory indicated by Ptolemy likely included the major late Iron Age hill-fort at Freestone Hill and a 1st-century Roman burial site at Stonyford, both in County Kilkenny.^[7]
• c100 - According to tradition, Osraige was founded by Óengus Osrithe in the 1st century and was originally within Laigin's polity.
• c150 - Óengus Osrithe flourishes as first king of the ancient kingdom of Osraighe).
• Loegaire Birn Buadach (fl. 1st or 2nd century AD) was the second king of Osraige after the death of his father, Óengus Osrithe. His epithet "Búadach" means "Victorious". His name became the appellation of his later descendants the Dál Birn who ruled Osraige until the Norman Invasion of Ireland.

• c300 - Agricultural activity increases and the population expands. Ringforts and Early Church sites develop.
• c350 - Christianity reaches Ireland.
• c380 - Roman artifacts at Freestone Hill and at a Stonyford burial site.

From the fifth century, the name Dál Birn ("the people of Birn"; sometimes spelled dál mBirn) appears to have emerged as the name for the ruling lineage of Osraige, and this name remained in use through to the twelfth century. From this period, Osraige was originally within the sphere of the province of Leinster.

• 431 - The first reliable historical event in Irish history, recorded in the Chronicle of Prosper of Aquitaine, is the ordination by Pope Celestine I of Palladius as the first bishop to Irish Christians in 431 - which demonstrates that there were already Christians living in Ireland. Prosper says in his Contra Collatorem that by this act Celestine "made the barbarian island Christian", although it is clear the Christianisation of the island was a longer and more gradual process.
• 432 - The mission of Saint Patrick is traditionally dated around the same time – the earliest date for his arrival in Ireland in the Irish annals is 432 – although Patrick's own writings contain nothing securely dateable.^[9][10] It is likely that Palladius' activities were in the south of Ireland, perhaps associated with Cashel, while Patrick's were later, in the north, and associated with Armagh.

The kingdom of Osraige, later anglicised as Ossory, was one of over 100 small kingdoms which existed in 8th century Ireland. In the middle years of the eighth century, Anmchad mac Con Cherca was the most militarily active king in Munster, and was the first Ossorian king to gain island-wide notice by the chroniclers.^[20]

The Osraige—their name means people of the Deer—inhabited much of modern County Kilkenny and parts of neighbouring County Laois. The most important churches were at Aghaboe (County Laois), chief church of Saint Cainnech, and at Seir Kieran (County Offaly), chief church of Saint Ciarán of Saighir.^[21]

• 749 - The men of Osraighe cause devastation in Fotharta Fea.
• 750 - The battle at Inis Snaic which Anmchad mac Con Cherca won, against whom is not stated, recorded in about 750, It may be that it concerned Leinster,^[31] the principal target of Anmchad's later wars was Leinster, and in particular the kingdoms and peoples of southern Leinster, modern County Carlow, chief among which were Uí Bairrche Tire and Uí Cheinnselaig.
• 754 - the Osraige ravaged a territory to their east known as Fotharta Fea, in the eastern portion of modern Carlow.^[32]

Accordingly, is presumed that Anmchad died at some time between his last appearance in 761 and the coming to power of Tóim Snáma in 769 or earlier.

• 769 - In 769 a war among the Osraige is recorded in which Tóim Snáma mac Flainn, apparently now ruling Osraige, defeated the sons of Anmchad's predecessor Cellach, among whom will have been his eventual successor Dúngal mac Cellaig.

The kingdom of Osraige, occupying roughly the same area as the present County Kilkenny, was considered part of Munster.

• 819 - Conchobar mac Donnchada succeeded Áed Oirdnide as Uí Néill over-king.
• c823 - Annals of the Four Masters record a victory by the foreigners (Norse) over the Osraighi.^[40]

Osraige had been subject for a period to the Eóganachta kings of Munster, but Feidlimid was succeeded by a series of weak kings who had to contend with Viking incursions on the coasts of Munster. As a result, Cerball was in a strong position and is said to have been the second most powerful king in Ireland in his later years.^[42]
• 856 - A victory was gained by Cearbhall, lord of Osraighe, and by Imhar (a Norse chieftain), in the territory of Aradh Tire, over the Cinel Fiachach, with the Gall Gaeidhil (the Dano-Irish) of Leath Chuinn. Four hundred above six thousand was the number which came with Cearbhall and Imhar.

• 863 King of Leinster, Muirecán mac Diarmata died. Domnall mac Muirecáin became King of Leinster, he was of the Uí Fáeláin sept of the Uí Dúnlainge branch of the Laigin. Francis John Byrne suggests that the Uí Dúnlainge kings exercised little real authority due to the aggressions of their western neighbour Cerball mac Dúnlainge, King of Osraige. Cerball, while unable to install himself as king of Leinster, was able to prevent any rival king exercising real power there.^[43]
