In 1916, militant Irish republicans staged a rising and proclaimed a republic. The rising was suppressed after six days with leaders of the rising being executed. This was followed by the Irish War of Independence in 1919–1921 and the Irish Civil War (1922–1923). After the civil war, the island was divided. Northern Ireland remained part of the United Kingdom, while the rest of the island became the Irish Free State. In 1927, the United Kingdom renamed itself the United Kingdom of Great Britain and Northern Ireland.
