Máel Sechnaill, who succeeded Brian Boru as the High King of Ireland in 976, successfully secured his kingship during a battle in which he emerged victorious against the Hiberno-Norse King of Dublin, Hamlaib Tara.

Sechnaill was a member of the Clann Cholmain Dynasty, a branch of Uá Néill which had dominated Ireland for generations and controlled the kingship of Tara – undoubtedly the most prestigious kingship in Ireland at the time.

For a long time, Sechnaill opposed Brian Boru, but after Boru gained the trust of the other Irish kings, Sechnaill was left with no option but to bow to his will.

Sechnaill shared the kingship of Ireland with Boru as he led the North. After Boru’s death, Sechnaill retained complete control of Ireland until he died in 1022. He is credited with ending the slavery of the Irish in England.

MacMurrough was the King of Leinster during the 12th century and was known for using force and brutality on his opponents, blinding and killing 17 of them!

In an attempt to hold on to his power, MacMurrough approached Henry II of England and offered to be his vassal if he would help him to reclaim Ireland.

MacMurrough became forever known afterwards as the man who invited England to Ireland, and many blame him for the following 800 years of conflict that occurred between the two nations.

Queen Maeve is one of the most well-known, well-liked, and written-about queens in Irish history and folklore.

Famous for being a passionate leader who inspired great loyalty in her followers who fought valiantly for her, Queen Maeve ruled over the province of Connacht in the West of Ireland with an iron fist.

Queen Maeve insisted on amassing equal wealth with her husband, Ailill mac Máta, so that they could rule the land equally together.

However, there was one aspect they were not equal in, as her husband possessed a prize bull that was more impressive than any in Maeve’s herd. Maeve was so power-hungry that she embarked on one of the most infamous tales in Irish mythology.

In what became known as ‘The Cattle Raid of Cooley’, Maeve successfully obtained Ulster’s prize bull and became a victorious queen of Ireland. However, many had to pay the ultimate price for her success.
