Uí Mháine, often Anglicised as Hy Many, was one of the oldest and largest kingdoms located in Connacht, Ireland.
The people of the kingdom were descendants of Maine Mór, who won the territory by warfare.
Its sub-kingdoms, also known as lordships, included – among others – Soghan, Corco Modhruadh, Delbhna Nuadat, Síol Anmchadha, and Máenmaige.
These kingdoms were made up of offshoots of the Uí Mháine dynasty, or subject peoples of different backgrounds.
[citation needed] The Uí Mhaine are among the ancient Irish dynasties still represented today among the recognised Irish nobility and Chiefs of the Name, by the O'Kelly of Gallagh and Tycooly, Prince of Uí Mhaine and Count of the Holy Roman Empire.
