The AIB parent company, Allied Irish Banks, plc.., originally named Allied Irish Banks Limited, was incorporated in Ireland in September 1966 as a result of the amalgamation of three long established banks: the Munster and Leinster Bank Limited (established 1885), the Provincial Bank of Ireland Limited (established 1825) and the Royal Bank of Ireland Limited (established 1836).

AIB is a financial services group operating predominantly in the Republic of Ireland and the UK. We provide a comprehensive range of services to personal, business and corporate customers in our target markets and have leading market shares in banking products in the Republic of Ireland. AIB’s business has been restructured in recent years with the aim of becoming a customer focused, profitable and lower risk institution, well positioned to support economic recovery in Ireland while seeking to generate sustainable shareholder returns.
