Battle of Callann
The Battle of Callann was fought in August 1261 between the Hiberno-Normans, under John FitzGerald, and three Gaelic clans: MacCarthy, who held the Kingdom of Desmond, under Fínghin Mac Carthaigh, King of Desmond, ancestor of the MacCarthy Reagh dynasty. It took place in the townland of Callann or Collon near modern-day Kilgarvan, County Kerry. MacCarthaigh was victorious. Background
Ousted King of Leinster, Diarmait Mac Murchada (Dermot MacMurragh), sought help in regaining his kingdom from Cambro-Norman mercenaries. The Normans landed at Bannow Bay, on the south coast of Leinster on 1 May 1169, seized Leinster within weeks and launched raids into neighbouring kingdoms. In the autumn of 1171, King Henry II of England decided to lead a military expedition to Ireland to establish his control over both the Norman warlords and the Irish. Norman expansion continued. Causes of the Battle 
In 1259, John FitzThomas FitzGerald, 1st Baron Desmond received a royal grant of Desmond and west Waterford in fee. Fineen MacCarthy, son of Donal Gott MacCarthy and King of Desmond gathered his troops. In July 1261 the MacCarthys decided to face the Normans at Callan and won a complete victory. Both John FitzGerald and his son, Maurice, died in the fighting. Contemporary accounts of the battle
