Timeline

1002–1010Tara · MeathBrian Boru claimed the Irish high kingship at Tara around 1002, demanding tribute from the provinces. Ulster king Máel Sechnaill mac Domnaill, Leinster powers, and the remnant Viking city-states were resistant, and tension grew between Ireland's 'over-kingdom of fifths' system and Brian's centralizing demands.
1010–1013Leinster and Dublin · LeinsterIn the 1010s, Leinster king Mael Morda stopped paying tribute and allied with Dublin's Viking king Sigtrygg Silkbeard. Máel Sechnaill briefly reconciled with Brian before turning against him again. The rebel forces formed an anti-Munster alliance, plunging Irish politics into a new round of armed confrontation.
1014–1016Clontarf and the Irish provinces · IrelandAt the Battle of Clontarf in 1014 Brian won a military victory but was killed, and his hegemonic system collapsed. Máel Sechnaill mac Domnaill again became high king around 1014–1016, but no one could rebuild island-wide dominance. Ireland returned to fragmentation among kings, and the title of high king thereafter became largely ceremonial.
