Ireland covers an area of ​​70,282 square kilometers. Located in the south-central part of the island of Ireland in western Europe. It is bordered by the Atlantic Ocean to the west, the British Northern Ireland to the northeast, and Britain across the Irish Sea to the east. The coastline is 3169 kilometers long. The central part is hills and plains, and the coastal areas are mostly highlands. The Shannon River, the longest river, is about 370 kilometers long. The largest lake is Lake Korib (168 square kilometers). It has a temperate maritime climate. Ireland is known as the "Emerald Island Country".

The country is divided into 26 counties, 4 county-level cities and 7 non-county-level cities. The county consists of urban areas and towns.

In 3000 BC, mainland European immigrants began to settle on the island of Ireland. In 432 AD, St. Patrick came here to spread Christianity and Roman culture. Entered the feudal society in the 12th century. Invaded by Britain in 1169. In 1171, King Henry II of England established the rule of love. The King of England became the King of Ireland in 1541. In 1800, the Treaty of the Love-British Alliance was signed and the United Kingdom of Great Britain and Ireland was established, which was completely annexed by Britain. In 1916, the "Easter Uprising" against Britain broke out in Dublin. With the upsurge of the Irish national independence movement, the British government and Ireland signed the Anglo-Irish Treaty in December 1921, allowing 26 counties in southern Ireland to establish a "free state" and enjoy autonomy. The 6 northern counties (now Northern Ireland) still belong to the United Kingdom. In 1937, the Irish Constitution declared the "Free State" a republic, but it remained in the Commonwealth. On December 21, 1948, the Irish Parliament passed a law declaring its separation from the Commonwealth. On April 18, 1949, Britain recognized the independence of love, but refused to return it to the 6 northern counties. After Ireland's independence, successive Irish governments have adopted the realization of the unification of Northern and Southern Ireland as an established policy.
