Question: When did Henry assume the title of King of Ireland
About the article "Dissolution of the Monasteries", section "Ireland".

Candidate passages:
Ireland King of Arms was the title of an officer of arms to the King of England and Lord of Ireland from 1392 until the accession of Henry VII as King of England in 1485.
A king of arms is the highest of the three levels of officers of arms, and usually enjoys heraldic jurisdiction over a geographical area.
Despite the name Ireland King of Arms did not appear to exercise heraldic authority in Ireland, and indeed the connection with Ireland seems rather tenuous.
The office may have been created preparatory to a subsequently aborted military expedition to Ireland.
The last holder of the office, Walter Bellinger, did exercise the heraldic prerogative of a king of arms to grant armorial bearings, however two of his grants were annulled or regranted by other kings of arms as they felt he encroached on their provinces.
In 1552, 70 years after the last Ireland King of Arms, the office of Ulster King of Arms was created.
The holders of this office exercised control over the heraldic affairs of Ireland until 1943, when the office was merged with that of Norroy King of Arms forming the present office of Norroy and Ulster King of Arms. 
Laudabiliter was a papal bull issued in 1155 by Adrian IV, an Englishman, giving the Angevin Henry II of England the right to assume control over Ireland and to enforce the Gregorian Reforms on the Catholic Church in Ireland.
The leaders of the Norman invasion of Ireland (1169–71) would later claim that Laudabiliter authorised the invasion.
Richard de Clare, a Cambro-Norman knight from Pembrokeshire, was retained by Diarmuid MacMorrough, the deposed King of Leinster, as an ally in his fight with the High King of Ireland, Ruaidrí Ua Conchobair.
In the event, successive Kings of England, from Henry II (1171) until Henry VIII (1541), derived the title and the authority of the "Lord of Ireland" from Adrian's successor, Pope Alexander III.
After almost four centuries, following the declaration of the independence of the Church of England from papal supremacy and rejection of the authority of Rome, a new basis for the English monarch's legitimate claim to the rule of Ireland was needed: the Crown of Ireland Act 1542 therefore established a sovereign Kingdom of Ireland with Henry being given the title of King of Ireland.
There has been some controversy over the authenticity of Laudabiliter. 
The Crown of Ireland Act 1542 is an Act of the Parliament of Ireland (33 Hen.
8 c. 1) which created the title of King of Ireland for King Henry VIII of England and his successors.
(The Kings of England had previously held only the title of Lord in relation to Ireland.
)The long title of the Act was "An Act that the King of England, his Heirs and Successors, be Kings of Ireland". 
In 1177, as the leader of the Norman invasion of Ireland, King Henry II of England created the title of Lord of Ireland for his youngest son John, who was not then expected to succeed to any other title.
John became king in 1199, and the title was held thereafter by the monarchs of England.
Under the Crown of Ireland Act 1542 The Lordship of Ireland was raised into the Kingdom of Ireland.
The Kingdom of Ireland continued after the Acts of Union 1707 which united the kingdoms of England and Scotland.
From King John (of the House of Plantagenet) to King Henry VIII (of the House of Tudor), English monarchs were also Lords of Ireland.
From King Henry VIII to Queen Anne (of the House of Stuart), English monarchs were also King or Queen of Ireland.
From Queen Anne to King George III (of the House of Hanover), British monarchs were also King or Queen of Ireland.
Note: In 1506 Lambert Simnel, an English pretender to the throne, was crowned Edward VI of Ireland  During the reign of George III of the United Kingdom the Kingdoms of Great Britain and of Ireland merged to become the United Kingdom of Great Britain and Ireland by the terms of the Act of Union 1800. 
The Anglo-Saxon kings of England used numerous different styles, including "King of the Anglo-Saxons" and "King of the English".
Grander variations were adopted by some monarchs; for example, Edred used "King of the Anglo-Saxons, Northumbrians, pagans and Britons".
These styles were sometimes accompanied by extravagant epithets; for instance, Æthelstan was "King of the English, raised by the right hand of the Almighty to the Throne of the whole Kingdom of Britain".
In Scotland the preferred title of the monarch was "King/Queen of Scots" rather than "of Scotland" (although the latter was by no means unknown).
William I, the first Norman monarch of England, used the simple "King of the English".
His successor, William II, was the first consistently to use "by the Grace of God".
Henry I added "Duke of the Normans" in 1121, though he had seized Normandy from his brother Robert in 1106.
In 1152 Henry II acquired many further French possessions through his marriage to Eleanor of Aquitaine; soon thereafter, he added "Duke of the Aquitanians" and "Count of the Angevins" to his style.
"King of the English", "Duke of the Normans", "Duke of the Aquitanians" and "Count of the Angevins" remained in use until King John ascended the Throne in 1199, when they changed to "King of England", "Duke of Normandy", "Duke of Aquitaine" and "Count of Anjou", respectively.
John, furthermore, was already the titular ruler of Ireland; therefore, he added "Lord of Ireland" to his style.
In 1204 England lost both Normandy and Anjou.
Nevertheless, they did not renounce the associated titles until 1259.
French territory once again became the subject of dispute after the death of the French King Charles IV in 1328.
Edward III claimed the French Throne, arguing that it was to pass to him through his mother Isabella, Charles IV's sister.
In France, however, it was asserted that the Throne could not pass to or through a woman.
Edward III began to use the title "King of France" (dropping "Duke of Aquitaine") after 1337.
In 1340 he entered France, where he was publicly proclaimed King.
In 1360, however, he agreed to relinquish his title to the French claimant.
Though he stopped using the title in legal documents, he did not formally exchange letters confirming the renunciation with the French King.
In 1369 Edward III resumed the title, claiming that the French had breached their treaty.
Henry V invaded France, but agreed to the Treaty of Troyes, whereby he was recognised as the Heir and Regent of France, in 1420.
He died in 1422, to be succeeded by his infant son, who became Henry VI.
Shortly after his accession, Henry VI also inherited the French Throne.
By the 1450s, however, England had lost all its territories in France, with the exception of Calais.
The claim to the title of "King of France" was nonetheless not relinquished until 1801, after the French monarchy was overthrown by the French Revolution.
After 1422 the royal style remained unchanged for almost a century.
Numerous amendments, however, were effected during Henry VIII's reign.
After Henry wrote a book against the Protestant Martin Luther, Pope Leo X rewarded him by granting the title "Defender of the Faith".
After disagreements with the Papacy over his marriage to Catherine of Aragon, Henry VIII broke away from the Roman Catholic Church, establishing the Church of England in 1533.
Pope Paul III rescinded the grant of the title "Defender of the Faith", but Henry continued to use it.
In 1535 Henry added "of the Church of England in Earth, under Jesus Christ, Supreme Head" to his style in 1535; a reference to the Church of Ireland was added in 1536.
Meanwhile, advised that many Irish people regarded the pope as the true temporal authority in their nation, with the king of England acting as a mere representative, Henry VIII changed "Lord of Ireland" to "King of Ireland" in 1542.
All changes made by Henry VIII were confirmed by an English Act of Parliament passed in 1544.
Mary I, Henry VIII's Catholic daughter, omitted "of the Church of England and also of Ireland in Earth Supreme Head" in 1553, replacing it with "etc.
", but the phrase remained part of the official style until an Act of Parliament to the contrary was passed in 1555.
In the meantime Mary had married the Spanish prince Philip.
The monarchs adopted a joint style, "King and Queen of England and France, Naples, Jerusalem and Ireland, Defenders of the Faith, Princes of Spain and Sicily, Archdukes of Austria, Dukes of Milan, Burgundy and Brabant, Count and Countess of Habsburg, Flanders and Tyrol", acknowledging both Mary's and Philip's titles.
Further changes were made after Philip became King of Spain and Sicily upon his father's abdication.
When the Protestant Elizabeth I ascended the Throne, she used the simpler "Queen of England, France and Ireland, Defender of the Faith, etc.
The "etc."
was added in anticipation of a restoration of the supremacy phrase, which never actually occurred.
After James VI, who was already King in Scotland, ascended the English Throne, the official style changed to "King of England, Scotland, France and Ireland, Defender of the Faith, etc.
"; his mother Mary, Queen of Scots, had already laid claim to these titles (in a different order, jointly with Francis II of France, then with the King's father, Lord Darnley), but she was beheaded by her Protestant opponent, Elizabeth I.
In 1604 James VI made a proclamation permitting the use of "King of Great Britain" instead of "King of England and Scotland".
This new style, though commonly used to refer to the King, was never statutory; therefore, it did not appear on legal instruments.
It did, however, appear on the inscriptions on coins.
England and Scotland were formally united into Great Britain in 1707 by the Act of Union.
Queen Anne consequently assumed the style "Queen of Great Britain, France and Ireland, Defender of the Faith, etc.".
It remained in use until 1801, when Great Britain and Ireland combined to become the United Kingdom.
George III used the opportunity to drop both the reference to France and "etc."
from the style.
It was suggested to him that he assume the title "Emperor", but he rejected the proposal.
Instead, the style became "King of the United Kingdom of Great Britain and Ireland, Defender of the Faith".
In 1876 "Empress of India" was added to Queen Victoria's titles, so that the Queen of the United Kingdom, the ruler of a vast empire, would not be outranked by her own daughter who had married the heir to the German Empire (an empire by the necessity of establishing a federal monarchy in which several kings wished to retain their royal titles despite their subjugation to a different monarchy).
Her successor, Edward VII, changed the style to reflect the United Kingdom's other colonial possessions, adding "and of the British Dominions beyond the Seas" after "Ireland".
In general usage the monarch came to be called the King-Emperor, especially in the Crown's overseas possessions and in British India and the princely states.
In 1922 the Irish Free State gained independence.
In 1927 the Royal and Parliamentary Titles Act 1927 changed the description "of the United Kingdom of Great Britain and Ireland and of the British Dominions beyond the Seas" to "of Great Britain, Ireland and the British Dominions beyond the Seas".
The 1927 Act was also significant for opening the door to dominions (later Commonwealth realms) having the right to determine their own style and title for the sovereign, a right which was first exercised in 1953.
The designation "Emperor of India" was dropped from the royal style in 1948, with retroactive effect as from the date of the independence of India and Pakistan a year earlier, even though King George VI remained king of both dominions.
Similarly, although the Republic of Ireland was constituted in 1949, "Great Britain and Ireland" was not replaced with "Great Britain and Northern Ireland" until 1953.
In the same year the phrase "Head of the Commonwealth" was also added, and "British Dominions beyond the Seas" was replaced with "other Realms and Territories".
Thus, the style of the present sovereign is "By the Grace of God, of the United Kingdom of Great Britain and Northern Ireland and of Her other Realms and Territories Queen, Head of the Commonwealth, Defender of the Faith".
Also in 1953, separate styles were adopted for each of the realms over which the sovereign reigned.
Most realms used the form, "Queen of ... and of Her other Realms and Territories, Head of the Commonwealth", omitting the title "Defender of the Faith".
Australia, New Zealand and Canada all included a reference to the United Kingdom as well as "Defender of the Faith", but only Canada still uses this form.
(Australia dropped both the reference to the United Kingdom and "Defender of the Faith" in 1973; New Zealand dropped the former in 1974.)
Grenada's style also includes reference to the "United Kingdom of Great Britain and Northern Ireland".
Curiously, the style used in Pakistan made mention of the United Kingdom, but not of Pakistan, perhaps because the nation was a Dominion only in the interim, whilst a republican constitution was being prepared.
