County Dublin (UK Parliament constituency)

County Dublin was a UK Parliament constituency in Ireland that existed from 1801 to 1885. It elected two Members of Parliament (MPs) using the bloc vote system.

Following the Acts of Union 1800, which merged the Kingdom of Great Britain and the Kingdom of Ireland into the United Kingdom of Great Britain and Ireland, the constituency was established in 1801. It replaced the former Parliament of Ireland constituency of the same name.

The constituency covered the geographic area of County Dublin, excluding Dublin City. Political representation in County Dublin was often contested, with landowners and those with strong ties to the agricultural sector being prominent figures. Over the years, representation shifted with the evolving political landscape and changing social dynamics of Ireland within the United Kingdom.

The constituency was abolished in 1885 under the Redistribution of Seats Act 1885. This act aimed to more fairly distribute parliamentary seats based on population size. As a result, County Dublin was divided into several new single-member constituencies, namely North Dublin and South Dublin, reflecting population growth and a move towards more localized representation. The act sought to address the perceived under-representation of certain areas and improve the fairness of the electoral system.
