Acts of Union 1800 The Acts of Union 1800 (sometimes erroneously referred to as a single Act of Union 1801) united the Kingdom of Great Britain and the Kingdom of Ireland (previously in personal union) to create the United Kingdom of Great Britain and Ireland with effect from 1 January 1801. The "Irish" Act (the Act of the (Old) Irish Parliament) however has since been repealed in the Republic of Ireland some time after Independence.
