A war of independence in the early 20th century was followed by the partition of the island, creating the Irish Free State, which became increasingly sovereign over the following decades, and Northern Ireland, which remained a part of the United Kingdom.
Northern Ireland saw much civil unrest from the late 1960s until the 1990s.
These Mesolithic communities lived as hunter-gatherers across the island until about 4000 BC.
Some time before 4000 BC, Neolithic settlers arrived introducing cereal cultivars, domesticated animals such as cattle and sheep, large timber building, and stone monuments.
Thick woodlands covered the island until the Middle Ages.
As of 2013, the amount of land that is wooded in Ireland is about 11% of the total, compared with a European average of 35%.It is separated from Great Britain to its east by the North Channel, the Irish Sea, and St George's Channel. It is the second largest island in the British Isles, after Great Britain.Politically, Ireland is divided between the Republic of Ireland (officially named Ireland), which covers five-sixths of the island, and Northern Ireland, which is part of the United Kingdom, in the northeast of the island.The culture of the island also shares many features with that of Great Britain, including the English language, and sports such as association football, rugby, horse racing, and golf.During the last glacial period, and up until about 10,000 BC, most of Ireland was periodically covered in ice.As a result, winters are milder than expected for such a northerly area.
