The Acts of Union 1800 were legislative measures that united the separate kingdoms of Great Britain and Ireland into a single entity known as the United Kingdom of Great Britain and Ireland. This union took effect on January 1, 1801, and aimed to create a more stable political environment and strengthen the British economy.
As a result of the Acts, the Irish Parliament was dissolved, and Irish representatives were sent to the British Parliament in Westminster. The union was motivated by various factors, including the desire for greater control over Irish affairs and the need to address issues arising from the French Revolutionary Wars.
