Trinity College Dublin (Irish: Coláiste na Tríonóide, Baile Átha Cliath), officially branded by the board as Trinity College, the University of Dublin, and by decree as The College of the Holy and Undivided Trinity of Queen Elizabeth near Dublin, is the sole constituent college of the University of Dublin in the Republic of Ireland. Founded by Queen Elizabeth I in 1592 through a royal charter, it is one of the extant seven ancient universities of Great Britain and Ireland. As Ireland's oldest university in continuous operation, Trinity contributed to Irish literature during the Victorian and Georgian eras and played a notable role in the recognition of Dublin as a UNESCO City of Literature.
Trinity was established to consolidate the rule of the Tudor monarchy in Ireland, with Provost Adam Loftus christening it after Trinity College, Cambridge. Built on the site of the former Priory of All Hallows demolished by King Henry VIII, it was the Protestant university of the Ascendancy ruling elite for over two centuries, and was therefore associated with social elitism for most of its history. Trinity has three faculties comprising 25 schools, and affiliated institutions include the Royal Irish Academy of Music, the Lir Academy, and the Irish School of Ecumenics. It is a member of LERU and the Coimbra Group. Trinity College Dublin is one of the two sister colleges of both Oriel College, Oxford, and St John's College, Cambridge, and through mutual incorporation, the three universities have retained an academic partnership (Oxon, Cantab, and Dubl) since 1636.
