The Irish Stock Exchange (ISE; Irish: Stocmhalartán na hÉireann) is Ireland's only stock exchange, and has been in existence since 1793. It was first recognised by legislation in 1799 when the Irish Parliament passed the Stock Exchange (Dublin) Act. At different periods in its history, the ISE included a number of regional exchanges, including the Cork and Dublin exchanges. In 1973, the Irish exchange merged with the other British and Irish stock exchanges becoming part of the International Stock Exchange of Great Britain and Ireland (now called the London Stock Exchange).
