Watch in

In 2022 we mark the centenary of Seanad Éireann, the Upper House of Ireland's Parliament.

Since its first meeting in Leinster House on 11 December 1922, the Seanad has reflected a broad range of views. Our programme of public lectures, exhibitions and initiatives aims to capture this diversity of perspectives, causes and changes to Irish life that Senators used their office to champion.

We have selected a notable debate from each decade to give a window into some of the issues that have come to the fore since the foundation of the State.

Bicameralism in Ireland

The Oireachtas is among the 41% of parliaments worldwide that have two chambers. Parliaments that have two chambers are referred to as "bicameral". Find out about the history that led to the creation of a bicameral parliament for Ireland.
