1834 Dublin and Kingstown Railway opened

The Dublin and Kingstown Railway (D&KR), which opened in 1834, was Ireland’s first railway. It linked Westland Row in Dublin with Kingstown Harbour in County Dublin. The Dublin and Kingstown Railway Company was founded in 1831 by businessmen in the city to look into building a railway. Within two years, they had a contractor and a parliamentary act. The construction contract was awarded to William Dargan. Building of the 10 km (6 mi) line was delayed by opposition from two different landowners who insisted on large cash compensations and in the case of Lord Cloncurry the building of a private foot bridge over the line to a bathing area complete with a Romanesque temple, a short tunnel and a cutting to maintain his privacy.

1831 Tithe War

The Tithe War was a campaign of nonviolent civil disobedience, punctuated by sporadic violent episodes, in Ireland between 1830 and 1836 in reaction to the enforcement of tithes on subsistence farmers and others for the upkeep of the established state church – the Church of Ireland. Tithes were payable in cash or kind and payment was compulsory, irrespective of an individual's religious adherence. The first clash of the Tithe War took place on 3 March 1831 in Graiguenamanagh, County Kilkenny, when a force of 120 yeomanry tried to enforce seizure orders on cattle belonging to a Roman Catholic priest. Encouraged by his bishop, he had organised people to resist tithe collection by placing their stock under his ownership prior to sale. The revolt soon spread.

1829 Roman Catholic Relief Act

The Roman Catholic Relief Act 1829, passed by Parliament in 1829, was the culmination of the process of Catholic Emancipation throughout Britain. In Ireland it repealed the Test Act 1673 and the remaining Penal Laws which had been in force since the passing of the Disenfranchising Act of the Irish Parliament of 1728. Its passage followed a vigorous campaign on the issue by Irish lawyer Daniel O'Connell. O'Connell had firm support from the Prime Minister, the Duke of Wellington, as well as from the Whigs and liberal Tories. The Act permitted members of the Catholic Church to sit in the parliament at Westminster. O'Connell had won a seat in a by-election for Clare in 1828 against an Anglican. Under the then extant penal law, O'Connell as a Roman Catholic, was forbidden to take his seat in Parliament.

1801 United Kingdom of Great Britain and Ireland

The United Kingdom of Great Britain and Ireland was established on 1 January 1801 under the terms of the Acts of Union 1800, by which the nominally separate kingdoms of Great Britain and Ireland were united. In 1922, twenty-six of thirty-two counties of Ireland seceded to form the Irish Free State (later becoming the Republic of Ireland) and, to reflect the change in the United Kingdom's boundaries, the Royal and Parliamentary Titles Act 1927 formally amended the name of the UK Parliament to the "Parliament of the United Kingdom of Great Britain and Northern Ireland".

1798 Battle of Castlebar

The Battle of Castlebar occurred on 27 August 1798 near the town of Castlebar, County Mayo, during the Irish Rebellion of that year. A combined force of 2,000 French and Irish routed a force of 6,000 British militia in what would later became known as the "Castlebar Races", or Races of Castlebar. Although achieving a spectacular victory, the losses of the French and Irish were high, losing about 150 men, mostly to the cannonade at the start of the battle. The British suffered over 350 casualties of which about 80 were killed, the rest either wounded or captured, including perhaps 150 who joined the republicans. Following the victory, thousands of volunteers flocked to join the French who also sent a request to France for reinforcements and formally declared an Irish Republic.

1782 Constitution of 1782

The Constitution of 1782 is a collective term given to a series of legal changes which freed the Parliament of Ireland, a Medieval parliament consisting of the Irish House of Commons and the Irish House of Lords, of legal restrictions that had been imposed by successive Norman, English, and later, British governments on the scope of its jurisdiction. This period came to be known as Grattan's Parliament after Henry Grattan, a major campaigner for reform in the House of Commons and leader of the Patriot Party. The new constitutional arrangements proved short-lived in consequence of the 1798 uprising by the United Irishmen. By the Acts of Union the Parliament of Ireland was abolished, and the Kingdom of Ireland absorbed into the new United Kingdom of Great Britain and Ireland, with effect from 1 January 1801.

1760 Battle of Carrickfergus

The Battle of Carrickfergus took place in February 1760 in Carrickfergus, Kingdom of Ireland during the Seven Years' War. A force of 600 French troops landed under the command of the Privateer François Thurot overwhelmed the small garrison of the town and captured its castle. Thurot held the town for five days, menacing nearby Belfast and demanding supplies and a ransom. In the face of the mobilisation of large numbers of local militia under General Strode, and the appearance of a Royal Navy squadron off the coast - Thurot re-embarked his force and departed the town.
