In 1798, a combined Protestant and Catholic Republican rebellion was defeated. This led to the Act of Union being passed in 1801, under which Ireland became a part of the United Kingdom. The Irish economy declined rapidly and the Great Famine ''An Gorta Mór'' broke out in 1845. The famine killed roughly one million, or one eighth of the entire population. It led to mass emigration to the United States, Canada and to Britain. | In 1798, a combined Protestant and Catholic Republican rebellion was defeated.
