County Mayo has a long history and prehistory.  throughout the county, there is a wealth of archaeological remains from the Neolithic period (about 4,000BC to 2,500BC), especially when it comes megalithic tombs and ritual stone circles.
Megalithic at Faulagh, Erris
The first people who came to Ireland – mainly coastal areas as the interior was heavily forest – arrived during the Middle Stone Age, as long as eleven thousand years ago.  The object of hunter / gatherers sometimes found in middens, garbage pits around the hearths where people would have rested and cooked over the large fireplaces. As rocks erode, Midden-remain the victim as blackened areas containing charred stones, bones and shells. They are usually a meter below the surface. Mesolithic people do not have great rituals associated with funerals, unlike the Neolithic (New Stone Age) period. 
The Neolithic period followed Mesolithic about 6000 years ago. People began to cultivate the land, domesticate animals for food and milk, and settle in one place for long periods. The people had the skills to make pottery, build houses of wood, weaving, and knapping (stone tools work). The first farmers cleared forest to graze cattle and grow crops. In North Mayo, where ground cover was flimsy, thin soils washed away and blanket bog covered the land is used by neolithic peoples.
Extensive pre-bog field systems have been discovered under the blanket bog, especially along the north Mayo coast of Erris and northern Tyrawley in places Ceide Fields, centered on the northeastern coast.
The Neolithic people developed rituals associated with burying their dead;that’s why they built large, complex, galleried stone tombs of their dead leader, known today as the megalithic tombs. There are over 160 registered megaliths in County Mayo, such Faulagh.
There are four different types of Irish megalithic Type– court tombs, portal tombs, passage tombs and wedge tombs -examples of all four types can be found in County Mayo.  Areas particularly rich in megalithic tombs include Achill, Kilcommon, Ballyhaunis, Killala and Behy / Glenurla area around Ceide Fields.
The Bronze Age (2500 BC to about 500 BC)
Megalithic tomb building continued into the Bronze Age, when the metal began working tools alongside stone tools. The Bronze Age lasted from about 4,500 years ago to 2,500 years ago (2,500BC to 500BC). Archaeological remains from this period include stone specializations, stone circles and fulachta fiadh (early cooking sites). They continued to bury their chiefs in megalithic tombs that changed the design during this period, more fuss wedge tomb type and casket funerals.
The Iron Age (500 BC to 500 AD approximately)
Approximately 2,500 years ago the Iron Age took over from the Bronze Age, as more and more metal took place. This is thought to have coincided with the arrival of the Celtic-speaking peoples and the introduction of the Irish ancestor. Towards the end of this period, the Roman Empire was at its height in the UK but it is not thought that the Roman Empire extended to Ireland to any great extent. Remains from this period, which lasted until the early Christian period began about 325AD (with the arrival of St. Patrick to Ireland as a slave) includes Crannogs (Lake homes), promontory fort, ring forts and Souterrains of which there are many examples across the county. The Iron Age was a time of tribal warfare with king ships, each struggling neighboring kings, vying for control of areas and take slaves. Areas marked by high stone markers, Ogham stones, with the help of the first written word, using the Ogham alphabet .Järnålders is the period during which the stories of the Ulster Cycle and the stories took place. The Táin Bó Flidhais which occurred mainly in Erris sets the scene well.
Early Christian period (325 AD – 800 AD approximately)
Statue of St. Patrick Aghagower
Christianity came to Ireland around the beginning of the 5th century. It took many changes, including the introduction of writing and recording events.Strain “tuatha” and the new religious settlements were side by side.Sometimes it suited chiefs to become part of the early churches, other times they remain as separate entities. Patrick (4th century AD) may have spent time in County Mayo and it is believed that he spent forty days and forty nights on Croagh Patrick pray for the people of Ireland. From the middle of the 6th century hundreds of small monastery settlements were established around the county.  Some examples of well-known early monastic sites in Mayo include Mayo Abbey, Aughagower, Ballintubber, Errew, Cong, Killala, Turlough on the outskirts Castlebar, and island settlements outside Mullet Peninsula and the islands Inishkea, Inishglora and Duvillaun.
In 795AD the first of the Viking raids took place. The Vikings came from Scandinavia to raid monasteries as they were places of wealth of precious metal processing takes place in them. Some of the major ecclesiastical settlements erected around the tower to prevent their valuable items looted and also to show their status and strength against these pagan raiders from the north. There are round towers on Aughagower, Balla, Killala, Turlough and Meelick. The Vikings established settlements that later evolved into cities (Dublin, Cork, Wexford, Waterford, etc ..) but no one was in County Mayo. Between the ages of Kings of Connacht, Cathal mac Conchobar mac Taidg (973-1010) and Tairrdelbach Ua Conchobair (1106-1156), various tribal areas incorporated into the kingdom of Connacht and controlled by Siol Muirdaig dynasty, originally based on Rathcroghan in County Roscommon, and from c. 1050 at Tuam. The families of O’Malley and O’Dowd Mayo served as admirals of the fleet of Connacht, while families O’Lachtnan, Mac Fhirbhisigh, O’Cleary was ecclesiastical and bardic clans.
Anglo-Normans (12th to 16th centuries)
From 1169 AD, when one of the warring kings (Dermot MacMurrough) in eastern Ireland appealed to the King of England for help in his fight with a neighboring king, the answer was the arrival of the Anglo-Norman colonization of Ireland. County Mayo came under Norman control in 1235AD. Norman control meant the eclipse of many Gaelic lords and chieftains, principally the O’Connors of Connacht.  During the 1230s, the Anglo-Normans and Welsh according to Richard Mór de Burgh (c. 1194-1242 invaded and settled in the county, introduce new families as Burke, Gibbons, Staunton, Prendergast, Morris, Joyce Walsh, Barrett, Lynott, Costello, Padden and price, Norman names are still common in County Mayo. After the collapse of domination in the 1330s, all these families became estranged from Anglo -irländska administration based in Dublin and is equivalent to the Gaelic-Irish, adopting their language, religion, dress, laws, customs and culture, and married for Irish families. they “became more Irish than the Irish themselves.”
The most powerful clan to emerge during this time was Mac William Burke, also known as Mac William Iochtar (see Burke Civil War 1333-1338), descended from Sir William Liath de Burgh, who defeated Gaelic-Irish at the Second Battle of Athenry in August 1316. they were often at war with their cousins, Clanricarde of Galway, and in alliance with or against different factions of O’Conor’s Siol Muiredaig and O’Kelly’s of Uí Maine. The O’Donnellär of Tyrconnell regularly invaded in an attempt to secure their right to rule.
Anglo Norman encouraged and established many religious orders from continental Europe to settle in Ireland. Mendicant orders-August, Carmelites, Dominicans and Franciscans started new settlements throughout Ireland, and built great churches, many under the patronage of prominent Gaelic families. Some of these sites include Cong, Strade, Ballintubber, Errew, Burrishoole Abbey and Mayo Abbey.  During the 15th and 16th centuries, despite periodic conflicts between them as England chopped and changed between the religious beliefs, the Irish usually considered the king of England as their king. When Elizabeth came to the throne in the mid 16th century, the English people, as was customary at the time, followed the religious practices of the reigning monarch and became Protestant. Many Irish Grainne O’Malley, had the famous pirate queen close relations with the British monarchy and the English kings and queens were welcome visitors to the Irish coast. The Irish, however, generally kept their Catholic religious practices and beliefs. The early crop of settlers in Ireland began in the Queen Mary in the middle of the 16th century and continued throughout the long reign of Queen Elizabeth I until 1603. When the term County Mayo had come into use. In the summer of 1588 the galleons of the Spanish Armada was destroyed by storms along the west coast of Ireland.Some of the unfortunate Spaniards came ashore in Mayo, only to be robbed and imprisoned, and in many cases slaughtered. Almost all religious foundations established by the Anglo-Normans were suppressed in the wake of the Reformation in the 16th century. 
Protestant settlers from Scotland, England, and elsewhere in Ireland, settled in the county in the early 17th century. Many were killed or forced to flee because of the 1641 Rebellion, during which a number of massacres committed avkatolska Gaelic Irish, especially on Shrule in 1642. One third of the total population reported to have died because of war, famine and plague between 1641 and 1653, with several areas remain disturbed and frequented avReparees to the 1670s.
17 and 18 centuries
Gráinne O’Malley meeting Queen Elizabeth 1
Pirate Queen Gráinne O’Malley is probably the most famous person from County Mayo from the mid-16th to the early 17th century.  In the 1640s, when Oliver Cromwell overthrew the British monarchy and establish a parliamentary government, hit Ireland seriously. With a strict regimen of absolute control to pay their armies and friends, the need to pay them with grants of land in Ireland led to the “to hell or Connaught policy.  displaced native Irish families from other (east and south mostly) parts of the country either forced to leave the country, often as slaves, or (if they were well behaved and compliant with the order of the parliamentarians) distributed land “west of the Shannon” and postpone his own country in the east. The land to the west was split and divided between the more and more people as the large estates were granted on the best land in the east to those most pleased the English.  Mayo does not seem to be affected much during Williamite war in Ireland, although many natives were banned and exiled .
Nephin Mountain, County Mayo
For most people in County Mayo 18th century was a period of unrelieved misery. Because of the criminal laws, Catholics had no hope of social advancement, while they remained in their homeland. Some, like William Brown (1777-1857), left Foxford with his family at the age of nine and thirty years later, was an admiral in the burgeoning Argentine Navy. Today he is a national hero in the country. 
The general unrest in Ireland felt as taut over Mayo and as the 18th century approached, and news reached Ireland of US frihetskrigetoch French revolution, the oppressed Irish, constantly suppressed by government policies and decisions from Dublin and London, began to gather for their own position against English rule in their country. By 1798 the Irish were ready for rebellion. The French came to help the Irish cause. General Humbert, from France landed in Killala with over 1000 officials where they began marching across the county to Castlebar, where there was an English garrison. Take them by surprise Humbert Army vann.Han established a “Republic of Connaught” with a Moore family from Moore Hall near Partry.Humbert’s army marched against Sligo, Leitrim and Longford where they suddenly faced a massive English army and forced to surrender in less than half an hour. The French soldiers were treated honor, but for the Irish handover meant slaughter. Many died on the scaffold in towns like Castlebar and Clare, where the high sheriff County Mayo, the Honourable Denis Browne, MP, brother of Lord Altamont, wreaked a terrible revenge – and thus earning himself the nickname that has survived in folk memory until today “Donnchadh a shout” (Denis ropes).
In the 18th century and early 19th century, sectarian tensions arose evangelical Protestant missionaries tried to “solve the Irish poor from the mistakes Popery”. One of the most famous was the pastor Edward Nangle behalf of Dugort Achill.  There were also the years of the campaign for Catholic Emancipation and later for the abolition of tithes, a predominantly Catholic population was forced to pay for the upkeep of the clergy of the established ( Protestant) church.
19th and 20th centuries
During the first years of the 19th century, famine was a common occurrence, especially when population pressure was a problem. The population of Ireland grew to over eight million people before the Irish Famine of 1845-1847 The Irish people depended on the potato crop for their livelihood. The disaster occurred in August 1845 when a killer fungus (later diagnosed as Phytophthora infestans) began destroying the potato crop. When widespread famine struck killed about one million people and another million left the country. People died in the fields from starvation and disease.The disaster was particularly poor in County Mayo, where almost ninety percent of the population dependent on potatoes as their basföda.Av 1848, Mayo County was a total misery and despair, with any attempt to ease measures in complete disarray. 
There are many reminders of the great famine seen at the Mayo landscape: Workhouse places, famine graves, places of soup kitchens, abandoned homes and villages and even traces of undug “lazy beds” in the field on the sides of mountains. Many roads and alleys were built as famine relief measures. There were nine workhouses in the county. Ballina, Ballinrobe, Belmullet, Castlebar, Clare, Killala, Newport, Swinford and Westport 
The distribution of iriska1871. Mayo relative remoteness meant that Irish is still widely spoken decades after the Great Famine and is still spoken today in the northwestern part of the county
A poor little place called Knock, County Mayo, made headlines when it was announced that an apparition of the Virgin Mary, St. Joseph and St. John had taken place at the August 21, 1879 was witnessed by fifteen local people. 
A national movement began in County Mayo in 1879 by Michael Davitt, James Daly and others, which led to the biggest social change ever seen in Ireland. Michael Davitt, a worker whose family had moved to England joined forces with Charles Stewart Parnell to win back the land for people from landlords and stop the eviction for nonpayment of rent. 
A new word came into the English language by an incident that occurred in Mayo. An English landlord named Captain Charles Cunningham Boycott was able to get some workers to do something for him, as uncomfortable as he was to them, so he brought in Protestant workers from elsewhere. He spent so much on the security and protection for his harvest cost him a fortune, and although no one in the area would serve him in business, or deal with him. This ostracisation became known as the “boycott” and Captain Boycott was left with no choice but to leave Mayo and take his family with him to England. 
“Land Question” gradually solved through a system of state-supported system for land purchases.  The tenants became owners of their countries during the recently set hinterland Commission.
A Mayo nun, Mother Agnes Morrogh-Bernard (1842-1932), established Foxford Woollen Mill in 1892. She made Foxford synonymous worldwide with high quality tweeds, rugs and blankets.   Mayo has remained an essentially countryside to the present.
