Connachta

The Connachta are a group of medieval Irish dynasties who claimed descent from the legendary High King Conn Cétchathach (Conn of the Hundred Battles). The modern western province of Connacht (Irish Cúige Chonnacht, province, literally "fifth", of the Connachta) takes its name from them, although the territories of the Connachta also included at various times parts of southern and western Ulster and northern Leinster. Their traditional capital was Cruachan (modern Rathcroghan, County Roscommon).
