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, who previously ruled the island as Lord of Ireland.
One of the earlier Christian overkingdoms, the Holy See of Rome, in 1171 abolished the High Kingship of Ireland (of 9th-century origin, successor to the Kingship of Tara) and devalued the ancient Kingdoms of Ireland.
Under Laudabiliter, a papal bull, the ancient realm was disestablished and turned into a feudal province of the Secretariat of State of the Roman Catholic Church under the temporal power of the monarch of England who henceforth held the title Lord of Ireland, relinquishing to the papacy annual the tribute levied upon the nobility and people of Ireland.
The secession of various European rulers during the Protestant Reformation, including Henry VIII, inspired the Papacy to initiate the Counter-Reformation. One consequence of this was that the Papacy required all Roman Catholic rulers to consider Protestant rulers (and their loyal subjects) as heretics, thus making their realms illegitimate under customary Roman Catholic international law. Consequently, the title "King of Ireland" was not initially recognised by Europe's Catholic monarchs and the Papacy. Instead, they remained committed in considering Ireland a feudal fief of the Papacy, to be granted to any Catholic sovereign who managed to secure the island Kingdom from the control of its Protestant monarchs.
After the death of Henry VIII's only legitimate son, Edward VI, the throne passed to his oldest daughter, Mary I, who was a devout Roman Catholic. Mary shortly thereafter married Philip of Spain, who was also staunchly Catholic. The new monarch restored papal authority in both England and Ireland. However, the status of Ireland as a kingdom remained in question: would the Papacy recognise Ireland's existence as a kingdom in its own right or maintain some fiction of temporal papal power in the land? To rectify this, Pope Paul IV issued a papal bull in 1555, Ilius, per quem Reges regnant, recognising Philip and Mary as King and Queen of England and its dominions including Ireland. Although this did not explicitly recognise Ireland as a kingdom, it represents the surrender of most of the Papacy's declared authority over Ireland, elevating it from a mere province of the Holy See to one that united Ireland's and England's crowns in one person.
Mary died without issue in 1558, and the thrones of England and Ireland passed to her half-sister, Elizabeth I, who was a Protestant. Once again, both kingdoms were removed from papal authority. In reply, Pope Pius V issued a papal bull in 1570, Regnans in Excelsis, declaring "Elizabeth, the pretended Queen of England and the servant of crime" to be a heretic and releasing all her subjects from any allegiance to her and excommunicating any that obeyed her orders.
Over the course of the next two centuries, the Papacy and Europe's Catholic rulers continued to recognise Ireland as a Kingdom in its own right, whilst at the same time asserting its Protestant monarchy as illegitimate. Simultaneously, they would incite Catholic rebellion to Protestants in the island as a means of recovering Ireland to a Catholic sovereign, preceding the establishment of a Catholic sovereign on the English and Scottish thrones. In reply, British diplomacy concentrated on receiving the recognition of the sovereignty of Ireland from Catholic Europe in the hope of thereby ending future Catholic sovereign incitements of the larger Catholic peasantry and securing the western flank of Great Britain from Catholic invasion.
Until 1801, Ireland continued to exist as a Kingdom in its own right, with its own Parliament. The government of Ireland, however, remained in English hands even after Grattan's constitution came into effect in the 1780s. Most of the country's population remained Catholic, but its Protestant minority remained socially, politically, and economically dominant; and even many Protestants were excluded from power as not being members of the established Church of Ireland. The Penal Laws preserving the position of the Protestant Ascendancy began to be dismantled in the 1780s and 1790s. However, fear of revolutionary violence in the wake of the French Revolution and the French Revolutionary Wars and subsequent republican Irish Rebellion of 1798 led the British government to seek the union of Ireland with Great Britain; this resulted in the formation of the United Kingdom of Great Britain and Ireland.
As a result of the Anglo-Irish Treaty that ended the Irish War of Independence, Ireland left the United Kingdom in 1922 and became the Irish Free State, a mostly self-governing Dominion that still retained the British monarch as its head of state. Shortly thereafter, six north-eastern counties (Northern Ireland) seceded from the Free State and rejoined the United Kingdom, but with their own parliament and system of government. Despite these fundamental changes, the 16th-century Act remained unamended on the statute books.
From a British perspective, the Irish Free State became legislatively independent with the passage in the British parliament of the Statute of Westminster 1931. However, the Irish Free State considered itself legislatively independent before its passage and did not recognize its legal situation as being changed. The country thereafter shared the person of its monarch with the United Kingdom and the other Dominions of the then-called British Commonwealth.
The Irish Free State adopted a new constitution in 1937, although the Irish monarchy was not abolished in UK law until the Republic of Ireland Act 1948. The Tudor Act remained on the republic's statute books until formally repealed in 1962.

What by a bold flight of imperialism we now denominate the Act of Annexation, (33d Hen. VIII. c. 1.) was in truth no more than an alteration in the Royal style.
