The Ulster or Northern Ireland Protestant community emerged after English Protestants colonized the Northern Parts. Those involved in managing the plantation seized any opportunity given to them to control and anglicize the predominantly Catholic population at the time. The influx of Scottish and English Protestants decisively changed the demographics of Ulster, which gave it a Protestant majority. Before this, Protestants only made a third of the population and in no time became an overwhelming majority.
The vast majority of Irish Protestants live in Northern Ireland. These Christians are also known as unionists partly because of their union with Great Britain. Unionism has further split the Ulster population into two main functions. The Ulster British – who identify themselves as the British, and the Ulster Loyalists – who prioritize their Protestantism before looking at their political affiliations.
Historically, there have always been more Protestants than Catholics in Northern Ireland. The scales have been shifting over the years, and the Protestant figures are slowly falling with 48% of people being Protestants, and 45% claiming to be Catholic. Population projections show that there is a real possibility of having more Catholics than Protestants in the next decade.
