The Irish peerage refers to the system of nobility in Ireland, which includes titles such as duke, marquess, earl, viscount, and baron. These titles were historically granted by the British monarch and were associated with land ownership and governance. The peerage played a significant role in Irish society, particularly from the 17th century until the early 20th century. Although the Irish peerage still exists, it has largely become ceremonial since the abolition of the Irish Parliament in 1800. Today, many titles are held by descendants of the original peers, but they no longer hold political power. The peerage remains a symbol of heritage and tradition in Ireland.
