Trinity College Dublin

The Institution of Dublin is a research university located in Dublin, Ireland. The only constituent college of the University of Dublin is Trinity College, which is formally known as The College of the Holy and Undivided Trinity of Queen Elizabeth near Dublin. The college was established in 1592 by Queen Elizabeth I as "the mother of a university" that was modelled after the collegiate universities of Oxford and Cambridge. However, unlike these affiliated institutions, only one college was ever established; as a result, the designations "Trinity College" and "University of Dublin" are usually synonymous for practical purposes. This is because the college was modelled after the collegiate universities of Oxford and Cambridge.

By virtue of the fact that Trinity College Dublin is a sister college to both St. John's College in Cambridge and Oriel College in Oxford, a person who has graduated from either Dublin, Oxford, or Cambridge can be awarded the equivalent degree at either of the other two universities without having to take any additional exams. According to the founding charter, "the Provost, Fellows, Foundation Scholars, and other members of the Board" are the individuals who are responsible for the formal incorporation of the institution. It is the oldest university in Ireland that is still in operation today, making it one of the seven ancient universities that may be found in Britain and Ireland. The main campus of the institution, which is located in the middle of Dublin, is often listed as one of the most iconic in the whole globe. It has also served as the backdrop for a number of books, films, and urban legends.

In 2009, when it was rated 43rd in the world by both the QS World Institution Rankings and the Times Higher Education, Trinity College Dublin made history by being the first and only Irish university to reach the Top 50 rankings of either of those two publications. It is now rated 98th in the world as of 2022, and in 2021, it was also regarded as the most international university in the European Union due to the fact that about thirty percent of its student body came from countries other than Ireland.

The first University of Dublin, also known as the Medieval University of Dublin and unrelated to Trinity College, was established in 1311 by Pope Clement V. It was given protection by the Crown and had a Chancellor, lecturers, and students for a number of years before coming to an end during the Reformation. Trinity College was not a part of the original University of Dublin.
