Dublin Castle administration in the context of "Kingdom of Ireland"

The Parliament of Ireland (Irish: Parlaimint na hÉireann) 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 ('lords temporal') and bishops ('lords spiritual'; after the Reformation, Church of Ireland 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 (15th century), Dublin Castle (to 1649), Chichester House (1661–1727), the Blue Coat School (1729–31), and finally a purpose-built Parliament House on College Green.

The main purpose of parliament was to approve taxes that were then levied by and for the Dublin Castle administration. Those who would pay the bulk of taxation, namely the clergy, merchants, and landowners, also comprised the members. Only the "English of Ireland" were represented until the first Gaelic lords were summoned during the 16th-century Tudor reconquest. Under Poynings' Law of 1495, all Acts of Parliament had to be pre-approved by the Irish Privy Council and English Privy Council. Parliament supported the Irish Reformation and Catholics were excluded from membership and voting in penal times. The Constitution of 1782 amended Poynings' Law to allow the Irish Parliament to initiate legislation. Catholics were re-enfranchised under the Roman Catholic Relief Act 1793.

Ireland was conquered by the Tudor monarchs of England in the 16th century. 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.

The Tudor policies in Ireland sparked the Desmond Rebellions (1569–1573, 1579–1583) and the Nine Years' War (1594–1603). Despite Spain sending an armada to support the Irish Catholics during the Anglo-Spanish War (1585–1604), by 1603 the entire country was under English rule. The Flight of the Earls in 1607 largely completed the destruction of the Gaelic aristocracy and left the way open for the Plantation of Ulster, which established a large British Protestant population in the north. Several people who helped establish the plantations of Ireland also played a part later in the early colonisation of North America, particularly a group known as the West Country Men.

The Irish Confederate Wars took place from 1641 to 1653. It was the Irish theatre of the Wars of the Three Kingdoms, a series of civil wars in Ireland, England and Scotland, all then ruled by Charles I. The conflict caused an estimated 200,000 deaths from fighting, as well as war-related famine and disease.

It began with the Irish Rebellion of 1641, when local Catholics tried to seize control of the Dublin Castle administration. They wanted an end to anti-Catholic discrimination, to increase Irish self-governance, and to roll back the Plantations of Ireland. They also wanted to prevent an invasion by anti-Catholic English Parliamentarians and Scottish Covenanters, who were defying the king. Rebel leader Felim O'Neill claimed to be doing the king's bidding, but Charles condemned the rebellion after it broke out. The rebellion developed into an ethnic conflict between Irish Catholics on one side, and English and Scottish Protestant colonists on the other. These first few months were marked by ethnic cleansing and massacres in Ulster.

The Nine Years' War (May 1593 – 30 March 1603) was a conflict in Ireland between a confederacy of Irish lords (with Spanish support) and the English-led government. The war was primarily a response to the English Crown's advances into territory traditionally owned by the Gaelic nobility. The war was also part of the Anglo-Spanish War and the European wars of religion.

The Kingdom of Ireland was established as an English client state in 1542, with various clans accepting English sovereignty under "surrender and regrant". By the early 1590s, widespread resentment against English rule developed amongst the Gaelic nobility, due to the execution of Gaelic lords, the pillaging of settlements by appointed sheriffs and Catholic persecution.

Irish measure or plantation measure was a system of units of land measurement used in Ireland from the 16th century plantations until the 19th century, with residual use into the 20th century. The units were based on "English measure" but used a linear perch measuring 7 yards (6.4 m) as opposed to the English rod of 5.5 yards (5.0 m). Thus, linear units such as the furlong and mile, which were defined in terms of perches, were longer by a factor of 14:11 (~27% more) in Irish measure, while units of area, such as the rood or acre, were larger by 196:121 (~62% more). The Weights and Measures Act 1824 (5 Geo. 4. c. 74) mandated the use throughout the British Empire of "Imperial measure", also called "statute measure", based on English measure. Imperial measure soon replaced Irish measure in the use of the Dublin Castle administration, but Irish measure persisted in local government, and longer still in private use.

The chief governor was the senior official in the Dublin Castle administration, which maintained English and British rule in Ireland from the 1170s to 1922. The chief governor was the viceroy of the English monarch (and later the British monarch) and presided over the Privy Council of Ireland. In some periods he was in effective charge of the administration, subject only to the monarch; in others he was a figurehead and power was wielded by others.

Traditional Irish clothing is the traditional attire which would have been worn historically by Irish people in Ireland. Such clothing among the men included the léine, brat and triúbhas while the women wore the leine, brat and gúna. These were the traditional items for centuries and are still worn today by a small number of enthusiasts. However, these items were at their height in the medieval period and went into a slow decline after the mid 17th century. During the 16th-century Tudor conquest of Ireland, the Dublin Castle administration prohibited many of Ireland’s clothing traditions. A series of photos captured by French photographers Marguerite Mespoulet and Madeleine Mignon-Alba in 1913 included images of Irish people in later clothing. Some of these photos were taken in Claddagh.

Aran jumpers were invented in the early 20th century and are not regarded as true traditional attire. Irish Tweed is a woven fabric that has been fashionable for centuries and used for the manufacture of the brat predominantly. In the past, much weaving was done in the home, with the fabric being delivered to a broker. Today, a few mills exist around Ireland which re-create this tweed in the traditional manner. Donegal is the heartland of Irish tweed and Donegal tweed is better known than other Irish tweeds.

The Irish House of Commons (Irish: Teach na gComóntach, Teach na dTeachtaí) was the lower house of the Parliament of Ireland that existed from 1297 until the end of 1800. The upper house was the House of Lords. The membership of the House of Commons was directly elected, but on a highly restrictive franchise, similar to the unreformed House of Commons in contemporary Great Britain. Catholics were disqualified from sitting in the Irish parliament from 1691, even though they comprised the vast majority of the Irish population.

The Irish executive, known as the Dublin Castle administration, under the Lord Lieutenant of Ireland, was not answerable to the House of Commons but to the British government. However, the Chief Secretary for Ireland was usually a member of the Irish parliament. In the Commons, business was presided over by the Speaker.
