The United Kingdom of Great Britain and Ireland was a sovereign state in Northwestern Europe that was established by the union in 1801 of the Kingdom of Great Britain and the Kingdom of Ireland. The establishment of the Irish Free State in 1922 led to the remainder later being renamed the United Kingdom of Great Britain and Northern Ireland in 1927.
Monarchical systems of government have existed in Ireland from ancient times. This continued in all of Ireland until 1949, when the Republic of Ireland Act removed most of Ireland's residual ties to the British monarch. Northern Ireland, as part of the United Kingdom, remains under a monarchical system of government.
The Acts of Union 1800 were parallel acts of the Parliament of Great Britain and the Parliament of Ireland which united the Kingdom of Great Britain and the Kingdom of Ireland to create the United Kingdom of Great Britain and Ireland. The acts came into force between 31 December 1800 and 1 January 1801, and the merged Parliament of the United Kingdom had its first meeting on 22 January 1801.
The Kingdom of Ireland was a dependent territory of England and then of Great Britain from 1542 to the end of 1800. It was ruled by the monarchs of England and then of Great Britain, and was administered from Dublin Castle by a viceroy appointed by the English king: the Lord Deputy of Ireland. Aside from brief periods, the state was dominated by the Protestant English minority. The Protestant Church of Ireland was the state church. The Parliament of Ireland was composed of Anglo-Irish nobles. From 1661, the administration controlled an Irish army. Although styled a kingdom, for most of its history it was, de facto, an English dependency. This status was enshrined in Poynings' Law and in the Declaratory Act of 1719.
Irish nationalism is a nationalist political movement which, in its broadest sense, asserts that the people of Ireland should govern Ireland as a sovereign state. Since the mid-19th century, Irish nationalism has largely taken the form of cultural nationalism based on the principles of national self-determination and popular sovereignty. Irish nationalists during the 18th, 19th, and 20th centuries such as the United Irishmen in the 1790s, Young Irelanders in the 1840s, the Fenian Brotherhood during the 1880s, Fianna Fáil in the 1920s, and Sinn Féin styled themselves in various ways after French left-wing radicalism and republicanism. Irish nationalism celebrates the culture of Ireland, especially the Irish language, literature, music, and sports. It grew more potent during the period in which all of Ireland was part of the United Kingdom, which led to most of the island gaining independence from the UK in 1922.
The Kingdom of England was a sovereign state on the island of Great Britain from the early tenth century, when it was unified from various Anglo-Saxon kingdoms, until 1 May 1707, when it united with Scotland to form the Kingdom of Great Britain, which would later become the United Kingdom. The Kingdom of England was among the most powerful states in Europe during the medieval and early modern periods.
The Parliament of Ireland was the legislature of the Lordship of Ireland, and later the Kingdom of Ireland, from 1297 until the end of 1800. It was modelled on the Parliament of England and from 1537 comprised two chambers: the House of Commons and the House of Lords. The Lords were members of the Irish peerage and bishops. The Commons was directly elected, albeit on a very restricted franchise. Parliaments met at various places in Leinster and Munster, but latterly always in Dublin: in Christ Church Cathedral, Dublin Castle, Chichester House (1661–1727), the Blue Coat School (1729–31), and finally a purpose-built Parliament House on College Green.
The history of the British Isles began with its sporadic human habitation during the Palaeolithic from around 900,000 years ago. The British Isles has been continually occupied since the early Holocene, the current geological epoch, which started around 11,700 years ago. Mesolithic hunter-gatherers migrated from the Continent soon afterwards at a time when there was no sea barrier between Britain and Europe, but there was between Britain and Ireland. There were almost complete population replacements by migrations from the Continent at the start of the Neolithic around 4,100 BC and the Bronze Age around 2,500 BC. Later migrations contributed to the political and cultural fabric of the islands and the transition from tribal societies to feudal ones at different times in different regions.
Ireland was part of the United Kingdom from 1801 to 1922. For almost all of this period, the island was governed by the UK Parliament in London through its Dublin Castle administration in Ireland. Ireland underwent considerable difficulties in the 19th century, especially the Great Famine of the 1840s which started a population decline that continued for almost a century. The late 19th and early 20th centuries saw a vigorous campaign for Irish Home Rule. While legislation enabling Irish Home Rule was eventually passed, militant and armed opposition from Irish unionists, particularly in Ulster, opposed it. Proclamation was shelved for the duration following the outbreak of World War I. By 1918, however, moderate Irish nationalism had been eclipsed by militant republican separatism. In 1919, war broke out between republican separatists and British Government forces. Subsequent negotiations between Sinn Féin, the major Irish party, and the UK government led to the signing of the Anglo-Irish Treaty, which resulted in five-sixths of the island seceding from the United Kingdom, becoming the Irish Free State, with only the six northeastern counties remaining within the United Kingdom.
The Protestant Ascendancy was the sociopolitical and economical domination of Ireland between the 17th and early 20th centuries by a small Anglican ruling class, whose members consisted of landowners, politicians, clergymen, military officers and other prominent professions. They were either members of the Church of Ireland or the Church of England and wielded a disproportionate amount of social, cultural and political influence in Ireland. The Ascendancy existed as a result of British rule in Ireland, as land confiscated from the Irish Catholic aristocracy was awarded by the Crown to Protestant settlers from Great Britain.
The Tudor conquestof Ireland took place during the 16th century under the Tudor dynasty, which ruled the Kingdom of England. The Anglo-Normans had conquered swathes of Ireland in the late 12th century, bringing it under English rule. In the 14th century, the effective area of English rule shrank markedly, and from then most of Ireland was held by native Gaelic chiefdoms. Following a failed rebellion by the Earl of Kildare in the 1530s, the English Crown set about restoring its authority. Henry VIII of England was made "King of Ireland" by the Crown of Ireland Act 1542. The conquest involved assimilating the Gaelic nobility by way of "surrender and regrant"; the confiscation and colonisation ('plantation') of lands with settlers from Britain; imposing English law and language; banning Catholicism, dissolving the monasteries and making Anglican Protestantism the state religion.
Ireland during the period of 1536–1691 saw the first full conquest of the island by England and its colonisation with mostly Protestant settlers from Great Britain. This would eventually establish two central themes in future Irish history: subordination of the country to London-based governments and sectarian animosity between Catholics and Protestants. The period saw Irish society outside of the Pale transform from a locally driven, intertribal, clan-based Gaelic structure to a centralised, monarchical, state-governed society, similar to those found elsewhere in Europe. The period is bounded by the dates 1536, when King Henry VIII deposed the FitzGerald dynasty as Lords Deputies of Ireland, and 1691, when the Catholic Jacobites surrendered at Limerick, thus confirming Protestant dominance in Ireland. This is sometimes called the early modern period.
The history of Ireland from 1691–1800 was marked by the dominance of the Protestant Ascendancy. These were Anglo-Irish families of the Anglican Church of Ireland, whose English ancestors had settled Ireland in the wake of its conquest by England and colonisation in the Plantations of Ireland, and had taken control of most of the land. Many were absentee landlords based in England, but others lived full-time in Ireland and increasingly identified as Irish.. During this time, Ireland was nominally an autonomous Kingdom with its own Parliament; in actuality it was a client state controlled by the King of Great Britain and supervised by his cabinet in London. The great majority of its population, Roman Catholics, were excluded from power and land ownership under the penal laws. The second-largest group, the Presbyterians in Ulster, owned land and businesses but could not vote and had no political power. The period begins with the defeat of the Catholic Jacobites in the Williamite War in Ireland in 1691 and ends with the Acts of Union 1800, which formally annexed Ireland in a United Kingdom from 1 January 1801 and dissolved the Irish Parliament.
The Crown of Ireland Act 1542 is an Act that was passed by the Parliament of Ireland on 18 June 1542, which created the title of "King of Ireland" for monarchs of England and their successors; previous monarchs had ruled Ireland as Lords of Ireland. The first monarch to hold the title was King Henry VIII of England.
The formation of the United Kingdom of Great Britain and Northern Ireland has involved personal and political union across Great Britain and the wider British Isles. The United Kingdom is the most recent of a number of sovereign states that have been established in Great Britain at different periods in history, in different combinations and under a variety of polities. Historian Norman Davies has counted sixteen different states over the past 2,000 years.
The first evidence of human presence in Ireland dates to around 34,000 years ago, with further findings dating the presence of homo sapiens to around 10,500 to 7,000 BCE. The receding of the ice after the Younger Dryas cold phase of the Quaternary, around 9700 BCE, heralds the beginning of Prehistoric Ireland, which includes the archaeological periods known as the Mesolithic, the Neolithic from about 4000 BCE, and the Copper Age beginning around 2500 BCE with the arrival of the Beaker Culture. The Irish Bronze Age proper begins around 2000 BCE and ends with the arrival of the Iron Age of the Celtic Hallstatt culture, beginning about 600 BCE. The subsequent La Tène culture brought new styles and practices by 300 BCE.
The Home Rule movement was a movement that campaigned for self-government for Ireland within the United Kingdom of Great Britain and Ireland. It was the dominant political movement of Irish nationalism from 1870 to the end of World War I.
Protestantism is a Christian minority on the island of Ireland. In the 2011 census of Northern Ireland, 48% (883,768) described themselves as Protestant, which was a decline of approximately 5% from the 2001 census. In the 2011 census of the Republic of Ireland, 4.27% of the population described themselves as Protestant. In the Republic, Protestantism was the second largest religious grouping until the 2002 census in which they were exceeded by those who chose "No Religion". Some forms of Protestantism existed in Ireland in the early 16th century before the English Reformation, but demographically speaking, these were very insignificant and the real influx of Protestantism began only with the spread of the English Reformation to Ireland. The Church of Ireland was established by King Henry VIII of England, who had himself proclaimed as King of Ireland.
The issue of Ireland has been a major one in British politics, intermittently so for centuries. Britain's attempts to control and administer the island, or parts thereof, have had significant consequences for British politics, especially in the 19th and 20th centuries. Although nominally autonomous until the end of the 18th century, Ireland became part of the United Kingdom of Great Britain and Ireland in 1801.
