Daniel O'Connell in the context of "Repeal Association"

A dream is a succession of images, dynamic scenes and situations, ideas, emotions, and sensations that usually occur involuntarily in the mind during certain stages of sleep. Humans spend about two hours dreaming per night, and each dream lasts around 5–20 minutes, although the dreamer may perceive the dream as being much longer.

The content and function of dreams have been topics of scientific, philosophical and religious interest throughout recorded history. Dream interpretation, practiced by the Babylonians in the third millennium BCE and even earlier by the ancient Sumerians, figures prominently in religious texts in several traditions, and has played a lead role in psychotherapy. Dreamwork is similar, but does not seek to conclude with definite meaning. The scientific study of dreams is called oneirology. Most modern dream study focuses on the neurophysiology of dreams and on proposing and testing hypotheses regarding dream function. It is not known where in the brain dreams originate, if there is a single origin for dreams or if multiple regions of the brain are involved, or what the purpose of dreaming is for the body (or brain or mind).

Sir John Gray JP (13 July 1815 – 9 April 1875), sometimes spelt John Grey, was an Irish physician, surgeon, newspaper proprietor, journalist and politician. Gray was active both in municipal and national government for much of his life, and had nationalist ideals – which he expressed as owner of the Freeman's Journal, chairman of the Dublin Corporation Water Works Committee between 1863 and 1875, and Member of Parliament in the House of Commons of the United Kingdom of Great Britain and Ireland for Kilkenny city from 1865 until his death. He was a supporter of Daniel O'Connell, and later of Charles Stewart Parnell, and advocated a repeal of the Act of Union. Through his offices with Dublin Corporation, the Vartry Reservoir water supply works were completed, introducing a freshwater supply to Dublin city and suburbs. He died at Bath in England on 9 April 1875. Shortly after his death, his contributions to the provision of the water supply, and the beneficial impact this had to conditions of public health in Dublin, were recognised in a memorial statue on O'Connell Street.

The Irish Conservative Party, often called the Irish Tories, was one of the dominant Irish political parties in Ireland in the 19th century. It was affiliated with the Conservative Party in Great Britain. Throughout much of the century it and the Irish Liberal Party were rivals for electoral dominance among Ireland's small electorate within the United Kingdom of Great Britain and Ireland, with parties such as the movements of Daniel O'Connell and later the Independent Irish Party relegated into third place. The Irish Conservatives became the principal element of the Irish Unionist Alliance following the alliance's foundation in 1891.

Young Ireland (Irish: Éire Óg, IPA: [ˈeːɾʲə ˈoːɡ]) was a political and cultural movement in the 1840s committed to an all-Ireland struggle for independence and democratic reform. Grouped around the Dublin weekly The Nation, it took issue with the compromises and clericalism of the larger national movement, Daniel O'Connell's Repeal Association, from which it seceded in 1847. Despairing, in the face of the Great Famine, of any other course, in 1848 Young Irelanders attempted an insurrection. Following the arrest and the exile of most of their leading figures, the movement split between those who carried the commitment to "physical force" forward into the Irish Republican Brotherhood, and those who sought to build a "League of North and South" linking an independent Irish parliamentary party to tenant agitation for land reform.

John Stanislaus Joyce (4 July 1849 – 29 December 1931) was the father of writer James Joyce, and a well known Dublin man about town. The son of James and Ellen (née O'Connell) Joyce, John Joyce grew up in Cork, where his mother's family, which claimed kinship to "Liberator" Daniel O'Connell, was quite prominent.

Baptised in St. Finbarr's South Church, Joyce grew up in the Anglesea Street area. He attended St Colman's College, Fermoy, from 1859 and later studied medicine at The Queen's College, Cork, from 1867. However, he did not complete his university studies.

The Oath of Supremacy required any person taking public or church office in the Kingdom of England, or in its subordinate Kingdom of Ireland, to swear allegiance to the monarch as Supreme Governor of the Church. Failure to do so was to be treated as treasonable. The Oath of Supremacy was originally imposed by King Henry VIII of England through the Act of Supremacy 1534, but repealed by his elder daughter, Queen Mary I of England, and reinstated under Henry's other daughter and Mary's half-sister, Queen Elizabeth I of England, under the Act of Supremacy 1558. The Oath was later extended to include Members of Parliament (MPs) and people studying at universities. In 1537, the Irish Supremacy Act was passed by the Parliament of Ireland, establishing Henry VIII as the supreme head of the Church of Ireland. As in England, a commensurate Oath of Supremacy was required for admission to offices.

In 1801, retained by the United Kingdom of Great Britain and Ireland, the oath continued to bar Catholics from Parliament until substantially amended by the Roman Catholic Relief Act 1829. The requirement to take the oath for Oxford University students was not removed until the Oxford University Act 1854.

O'Connell Street (Irish: Sráid Uí Chonaill) is a street in the centre of Dublin, Ireland, running north from the River Liffey. It connects the O'Connell Bridge to the south with Parnell Street to the north and is roughly split into two sections bisected by Henry Street. The Luas tram system runs along the street.

During the 17th century, it was a narrow street known as Drogheda Street, named after Henry Moore, 1st Earl of Drogheda. It was widened in the late 18th century by the Wide Streets Commission and renamed Sackville Street (Sráid Saicfil) after Lionel Sackville, 1st Duke of Dorset. In 1924, it was renamed in honour of nationalist leader Daniel O'Connell, whose statue by John Henry Foley stands at the lower end of the street facing O'Connell Bridge.

The history of the Jews in England can be reliably traced to the period following the Norman Conquest of 1066, when England became integrated with the European system for the first time since the Roman evacuation of 410 CE, and thus came to the awareness of the Jewish communities of Continental Europe.The first Jews likely came to England circa 70 CE during the time of Roman rule, but were probably wiped out in the tumultuous period that followed the Roman evacuation, when the Anglo-Saxons gradually took power from the Romano-Celts.

In 1290 King Edward I issued the Edict of Expulsion, expelling all Jews from the Kingdom of England. After the expulsion, there was no overt Jewish community (as opposed to individuals practising Judaism secretly) until the rule of Oliver Cromwell. While Cromwell never officially readmitted Jews to the Commonwealth of England, a small colony of Sephardic Jews living in London was identified in 1656 and allowed to remain. The Jewish Naturalisation Act 1753, an attempt to legalise the Jewish presence in England, remained in force for only a few months. Historians commonly date Jewish emancipation to either 1829 or 1858, while Benjamin Disraeli, born a Sephardi Jew but converted to Anglicanism, had been elected twice as the prime minister of the United Kingdom in 1868 and in 1874. At the insistence of Irish leader Daniel O'Connell, in 1846 the British law "De Judaismo", which prescribed a special dress for Jews, was repealed.
