The town of Sligo was founded in 1243 AD by the Norman knight Maurice Fitzgerald and Fedlim O'Conchobar the Rí Coiced (Provincial King) of Connacht. Norman influence appears to have lasted for about 60 years. From around 1310, after the Gaelic resurgence, the town existed well within the Gaelic cultural zone and developed on the Sligeach (Garavogue) river under the O’Conchobhar Sligigh dynasty and within the Irish túath of Cairbre Droma Cliabh as part of the Gaelic confederation of (Lower Connacht) until the creation of County Sligo by the English Lord Deputy Henry Sidney in 1561.
