List of Irish royal consorts
There have been no Gaelic queens of all Ireland since the late 12th century, following the complex sequence of the Norman invasion of Ireland, Treaty of Windsor (1175), and death of the last true High King of Ireland, Rory O'Connor, in 1198. However, there were many provincial Gaelic queens in subsequent centuries until the final Tudor conquest in 1603.
