Bellaslishen and Roscommon

Abstract
In 1288 Magnus Ó Conchobair seized Connacht after defeating and capturing his brother Cathal at Bellaslishen, a strategic ford near Roscommon. His victory brought plundering, but winter attacks at Ros Mór wounded him and exposed continuing resistance. Recovering, he took hostages in Síl Muiredaig to enforce obedience. Richard de Burgh, Red Earl of Ulster and lord of Connacht, advanced to Roscommon but withdrew amid opposition, although sources dispute subsequent terms. Stephen de Fulbourn, archbishop of Tuam and justiciar, died, prompting William de Bermingham's election. Changes in church and chancery office reflected contested authority among Gaelic rulers, magnates and royal administration.
