When did the Acts of Union 1800, which was represented in Parliament by such unions as New Ross, take effect?
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 The "Irish" Act (the Act of the (Old) Irish Parliament) however has since been repealed in the Republic of Ireland some time after Independence.
Peerage of the United Kingdom The Peerage of the United Kingdom comprises most peerages created in the United Kingdom of Great Britain and Ireland after the Act of Union in 1801, when it replaced the Peerage of Great Britain. New peers continued to be created in the Peerage of Ireland until 1898 (the last creation being the Barony of Curzon of Kedleston).
