A t the battle of Clontarf in 1014 Irish high king Brian Boru sent Viking invaders tumbling back into the sea and achieved a remarkable victory for the Irish over the fearsome Vikings.
The two armies met on the fields of Clontarf near the city of Dublin on Good Friday in the spring of 1014. The battle lasted all day raging across the fields and forests with no side gaining a clear advantage. Finally, with all of their leaders dead or dying, the Vikings broke ranks and returned to their ships.
Out of 8,000 men who fought that day, almost 6,000 were killed. The destruction of the Viking forces, including the deaths of virtually all of the Viking kings, permanently ended the Invaders' presence. Through this valiant and bloody victory at Clontarf, Brian Boru and his men made possible the Ireland that we know today.
