Dublin was the heart of the area known as the Pale, a narrow strip of English settlement along the eastern coast, under the control of the English Crown. The Tudor conquest of Ireland in the 16th century spelt a new era for Dublin, with the city enjoying a renewed prominence as the centre of administrative rule in an Ireland where English control and settlement had become much more extensive. Determined to make Dublin a Protestant city, Queen Elizabeth I of England established Trinity College in 1592 as a solely Protestant university and ordered that the Catholic St. Patrick's and Christ Church cathedrals be converted to the Protestant church.
