Ireland has four big parts. 
Long ago, there were five parts. The name for a province means "a fifth." This shows how the land was split up.
Old stories tell of many kings. These kings ruled their own lands. Some kings were even more powerful than others.

Today, the provinces are for culture. They help people feel connected to the past.
Ireland is divided into four big parts. These are called provinces. 

In the past, things were different. The Irish word for province means "a fifth." This suggests there were once five parts. Some people think Meath was the fifth part. In old legends, there were five kingdoms. These were called the Pentarchy. Each kingdom had its own king. These kings were of equal rank. They did not follow one single ruler.

Ireland is divided into four large areas called provinces. These are Connacht, Leinster, Munster, and Ulster. 

Long ago, Ireland was known as the Pentarchy. This means it was made of five independent kingdoms. 
Old legends tell many stories about these early times. The Ulster Cycle is a famous set of tales. 
In the early medieval period, the land had many layers of rulers. A province was ruled by a king of over-kings. This person was also called a king of a fifth.
Many different groups fought to control these lands over time. The Three Collas are famous figures from an old myth. They were said to be the sons of Eocaidh Doimlén. They fought seven battles against the Ulaid people. After these battles, they founded the kingdom of Airgíalla. This kingdom covered parts of modern Armagh, Fermanagh, Londonderry, Monaghan, and Tyrone. Later, the Normans arrived in Ireland in 1170. This changed the kingdoms and helped create the modern counties we see today. The old provinces remain as important pieces of Irish history.
Ireland is divided into four distinct provinces: Connacht, Leinster, Munster, and Ulster. 

Ancient legends describe a period known as the Pentarchy. This era is often called the "Time of the Five Fifths" or the "Time of the Provincial Kings." 
Historians have debated the exact nature of this ancient division. Eoin MacNeill argued that the Pentarchy was a pre-historic and pre-Gaelic fact. The division is often linked to the death of specific legendary figures. Some sources, like the Annals of Tigernach, claim the division followed the slaying of Conaire Mór. Others suggest it occurred upon the death of his father, Eterscél Mór. Even the legendary Ulster Cycle, set in the 1st century, reflects these early divisions. 
During the early medieval period, Ireland utilized a complex hierarchical structure of lordship. At the top was the king of over-kings, also known as a *rí co fressabra*. This title was later replaced by *rí cúige*, meaning "king of a fifth." Below the provincial level were several petty-kingdoms. These units were roughly the size of modern counties or dioceses. They were ruled by an overking known as a *rí*. These were further subdivided into smaller groups called *túath*. A *túath* was a group of people similar to a barony. These were ruled by a king, or *rí túaithe*. By the 10th century, these rulers were often called lords or leaders instead.
Mythology also explains the rise of specific territories, such as Airgíalla. The myth of the Three Collas tells of three brothers: Colla Menn, Colla Da Crioch, and Colla Uais. They were the sons of Eocaidh Doimlén. According to the story, they were sent to conquer land to establish their own descendants. They fought seven battles against the Ulaid over seven days. After the seventh battle, the king of Ulaid, Fergus Foga, was killed. The Collas then took possession of central Ulaid. This territory covered modern counties Armagh, Fermanagh, Londonderry, Monaghan, and Tyrone. This area became the over-kingdom of Airgíalla.
Political shifts also changed the landscape of Munster and Osraige. In the 12th century, the kingdom of Osraige was part of Mumu. However, it eventually became an independent kingdom. In 1118, the king of Connacht aided a rebellion in south Munster. This led to the division of Mumu into two parts: Thomond in the north and Desmond in the south.
Following the Norman invasion in 1170, the political structure changed again. The kingdoms of Connacht, Desmond, Leinster, Meath, Thomond, and Ulster became the basis for Norman liberties. These liberties were later subdivided into smaller units. These smaller units eventually became the modern counties of Ireland. While the old over-kingdoms like Airgíalla eventually lost their status, their influence remained. The last king of Airgíalla, Hugh Roe McMahon, reigned until his execution in 1590. Today, the provinces stand as a testament to the long and complex history of the island.
