Overview

The Irish Parliament (Irish: Parlaimint na hÉireann) was the principal legislative body that represented the Anglo‑Norman and later Anglo‑Irish political order in Ireland from the late 13th century until its abolition in 1800. Created in the medieval period, it evolved into a bicameral assembly broadly modelled on the Parliament of England, with an upper chamber of peers and a lower chamber of commons. Over centuries its authority and composition reflected the changing balance between local interests, English royal power and religious exclusions.

Structure and functions

The institution was a legislature in the formal sense: it met to pass statutes, to consent to taxation, and to advise the crown on Irish affairs. Its two houses were the House of Lords and the House of Commons, staffed mainly by Anglo‑Irish magnates, bishops and representatives of boroughs and counties. For basic orientation it behaved like other contemporary parliaments: debating petitions, voting supplies and enacting laws subject to royal assent.

Constraints and legal controls

The parliament's independence was repeatedly curtailed. From the late 15th century Poynings' Law (enacted under Sir Edward Poynings) required that legislation proposed by the Irish assembly first receive approval from the English council and monarch, effectively subordinating Irish parliamentary initiative to London. The crown and its deputies retained patronage that shaped membership and outcomes. Religious restrictions — especially the Penal Laws of later centuries — largely excluded Roman Catholics from membership, so the native Gaelic population and most Catholics had little direct representation.

Reforms, the 1782 relief and the Act of Union

By the 18th century Irish politics produced movements for greater autonomy. A period of constitutional change culminated in 1782 when acts and political pressure weakened Poynings' constraints and granted the Irish Parliament greater legislative freedom, a phase often called "Grattan's Parliament" after an influential advocate. That autonomy proved short‑lived: the Irish and British parliaments passed the Act of Union in 1800 (effective 1801), which dissolved the Irish legislature and incorporated Ireland into the United Kingdom of Great Britain and Ireland. Thereafter Ireland was represented in the Parliament of the United Kingdom at the Palace of Westminster.

Founding date: commonly dated to assemblies in the late 13th century (circa 1297), when regular parliaments first met for the Anglo‑Irish community.
Major constraint: Poynings' Law (1494), limiting Irish legislative initiative until 1782.
Religious exclusion: Penal legislation effectively barred most Catholics from parliamentary seats for much of the early modern period.
Abolition: Act of Union 1800 ended the independent Irish legislature; representation moved to Westminster.

Legacy and significance

The historic Irish Parliament is important for understanding Ireland's constitutional development: it illustrates tensions between local self‑government and imperial control, the political consequences of religious exclusion, and the eventual centralization of British rule. Its brief late‑18th‑century autonomy influenced later nationalist and reform movements, and the memory of a Dublin legislature informed subsequent constitutional arrangements in the 20th century, including the parliament of the independent Irish state. For further reading on its name, form and evolution see contemporary guides and historical summaries at legislature resources and specialized studies referenced through archival portals and library collections (Commons, Lords entries).

Many introductions and records use the Irish language form and discuss institutional change: see entries and source collections linked under Parlaimint na hÉireann and related legislative histories (comparisons with England, integration into the UK).

History

The Parliament of Ireland originally came into being in the 13th century as a representation of the Anglo-Norman landlords in Ireland. The original Gaelic inhabitants were not represented or entitled to vote. However, in the 14th and 15th centuries the number of English inhabitants in Ireland fell dramatically - only a small enclave around Dublin, known as the Pale, remained. Parliament therefore became mainly a forum of this enclave until the 17th century. The inhabitants of the Pale then urged the King of England to play a more leading role in Ireland to protect them from the Gaelic-Irish nobles. By the Poynings' Law (1494), the Parliament of Ireland became subordinate to the English Parliament and thus lost power.

The role of the Irish Parliament changed in 1541 when Henry VIII proclaimed the "Kingdom of Ireland" and the re-conquest of Ireland by the Tudors began. The Protestant Reformation of the Tudors and the introduction of the Anglican state church changed the political picture in Ireland, as the majority of the population was still of Roman Catholic denomination, which led to fierce disputes in the Irish Parliament. In 1613 to 1615, therefore, constituencies for Parliament were drawn up precisely so that the English and Scottish settlers constituted the majority of the members of the Irish Parliament. Now the Irish Parliament served - once again - to represent the English, but now Protestant, minority. In the following period, the Anglo-Irish Parliament often tried (unsuccessfully) to achieve independence from London. Then, in the early 18th century, it successfully campaigned to be convened every two years - previously this had been dependent on the whims of the British king - shortly afterwards it even achieved permanent "attendance", a development similar to that of the British Parliament. Furthermore, the Parliament fought for greater powers over the (superior) British Parliament as well as better trading conditions with Great Britain.

Many public ceremonies in Ireland were modelled on the British Parliament. The parliamentary season was officially opened with the Speech from the Throne by the Lord Lieutenant of Ireland, who sat on a throne of purple velvet. During the parliamentary sessions, the wealthiest Anglo-Irish elite moved to Dublin, as this period was often accompanied by balls and festivities. Members of the high nobility in particular flocked to Dublin, where they lived in huge and richly decorated residences - initially in the northern part of Dublin, and later in the new Georgian residences around Merrion Square and Fitzwilliam Square. Their presence in the city helped it to a real economic boom.

The House of Lords (Irish House of Lords)

The Irish House of Lords was the upper house of the Parliament of Ireland. It also acted as the Supreme Court of the Kingdom of Ireland.

The House of Lords was presided over by the Lord Chancellor of Ireland, who sat on what was known as the 'woollen sack' - a very large chair which had neither arm nor backrest, and whose purple cushion was filled with wool from all three 'lands' of the United Kingdom (England, Scotland, Ireland).
