The American Colonies Act 1766 (6 Geo 3 c 12), commonly known as the Declaratory Act, was an Act of the Parliament of Great Britain, which accompanied the repeal of the Stamp Act 1765 and the changing and lessening of the Sugar Act.
 Parliament repealed the Stamp Act because boycotts were hurting British trade and used the declaration to justify the repeal and save face.
 The declaration stated that the Parliament's authority was the same in America as in Britain and asserted Parliament's authority to pass laws that were binding on the American colonies.
The Irish Confederation was an Irish nationalist independence movement, established on 13 January 1847 by members of the Young Ireland movement who had seceded from Daniel O'Connell's Repeal Association.
 Historian T. W. Moody described it as "the official organisation of Young Ireland".
Young Ireland (Irish: "Éire Óg" , ] ) was a political, cultural and social movement of the mid-19th century.
 It began as a tendency within Daniel O'Connell's Repeal Association, associated with "The Nation" newspaper, but eventually split to found the Irish Confederation in 1847.
 Young Ireland led changes in Irish nationalism, including an abortive rebellion known as the Young Irelander Rebellion of 1848.
 Many of the rebellion's leaders were tried for sedition and sentenced to penal transportation to Van Diemen's Land.
 From its beginnings in the late 1830s, Young Ireland grew in influence and inspired following generations of Irish nationalists.
 Some of the junior members of the movement went on to found the Irish Republican Brotherhood.
The Acts of Union 1800 (sometimes erroneously referred to as a single Act of Union 1801) united the Kingdom of Great Britain and the Kingdom of Ireland (previously in personal union) to create the United Kingdom of Great Britain and Ireland with effect from 1 January 1801.
 The "Irish" Act (the Act of the (Old) Irish Parliament) however has since been repealed in the Republic of Ireland some time after Independence.
The European Union (Withdrawal) Bill, also known as the Repeal Bill or the Great Repeal Bill, is a bill of the Parliament of the United Kingdom that proposes to transpose directly-applicable European Union law into the law of the United Kingdom, as part of the country’s exit from the European Union (Brexit).
 To implement this, the proposed bill will repeal the European Communities Act 1972 which first brought the UK into what became the EU, incorporate all EU law into the UK statute books, and give ministers the power to adapt and remove laws that are no longer relevant.
The 1832 British general election in Ireland saw the emergence of the Repeal Association as a major political movement in Ireland.
 The Association, led by Daniel O'Connell, aimed to repeal the 1800 Acts of Union and restore Ireland to the status enjoyed under Grattan's Parliament, although this time with Catholic emancipation.
The Party Processions Act ("13 & 14 Vict c2") was an 1850 Act of Parliament in the United Kingdom which prohibited open marching, organised parades and sectarian meetings in Ireland in order to outlaw provocative movements in the wake of the Dolly's Brae fighting of 1849.
 Written on 8 February, the Act was assembled against people "in the practice of assembling and marching together in procession in Ireland in a manner calculated to create and perpetuate animosities between different classes of Her Majesty's Subjects, and to endanger the public peace."
 Actions such as using banners, emblems and flags constituted an offence, as did music "calculated or tend to provoke animosity".
 Violation of the Act was classed as a misdemeanor.
 The Act was strongly supported by Sir Robert Peel however opposed by other politicians such as Lord Claude Hamilton who argued that religious parades would also be outlawed, yet posed no threat.
 The "Party Emblems Act" was passed in 1860 to further support this measure following further riots at Derrymacash.
 The Act was "grudgingly" accepted by the Orangemen, however both the Irish Republican Brotherhood, the Young Ireland movement, and related Fenian movements were less placated.
 William Johnston of Ballykilbeg led a radical Orangemen group in defiance of the act during the 1860s, and was imprisoned – prompting strong demand for its repeal in 1867, which succeeded in 1872.
 The issue and repeal of the Act is viewed as an important milestone by nationalist historians of Ireland, and is said to be an example of Irish suppression by the "English" government.
 Peel, however, was one of a number of Members of Parliament who viewed the Act as a necessity to prevent Catholic and Protestant in-fighting rather than Irish nationalism as a whole.
 Traditional, revisionist and post-revisionist historians have subsequently supported either viewpoint and the Act remains a controversial one.
The Tivoli Theatre in Dublin, Ireland, started life as the Conciliation Hall in 1834.
 Located on Burgh Quay, Dublin 2; It was built as a meeting place for Daniel O'Connell's Repeal Association.
 In 1897, it was rebuilt as a concert hall called the Grand Lyric Hall and changed name to the Lyric Theatre of Varieties the following year.
 It became known as the Tivoli in 1901.
 It was a modest sized music hall with seating for 1252 patrons.
The Repeal Association was an Irish mass membership political movement set up by Daniel O'Connell in 1830 to campaign for a repeal of the Acts of Union of 1800 between Great Britain and Ireland.
An Act for the better securing the dependency of the Kingdom of Ireland on the Crown of Great Britain (6.
 Geo.
 I, c. 5) was a 1719 Act passed by the Parliament of Great Britain which declared that it had the right to pass laws for the Kingdom of Ireland, and that the British House of Lords had appellate jurisdiction for Irish court cases.
 It became known as the Declaratory Act, and opponents in the Irish Patriot Party referred to it as the Sixth of George I (from the regnal year it was passed).
 Legal and political historians have also called it the Dependency of Ireland on Great Britain Act 1719 or the Irish Parliament Act, 1719.
 Prompted by a routine Irish lawsuit, it was aimed at resolving the long-running dispute between the British and the Irish House of Lords as to which was the final court of appeal from the Irish Courts.
 Along with Poynings' Law, the Declaratory Act became a symbol of the subservience of the Parliament of Ireland, and its repeal was long an aim of Irish statesmen, which was finally achieved as part of the Constitution of 1782.
