Ierne is fairly obviously a mispronunciation of 'Er Inis' or 'Eire Innis' (various spellings are available), meaning 'West Island' in common Celtic. The name remains in use today in its full form - Eireann.(Information by Peter Kessler, with additional information by Edward Dawson, and from Marie Mc Keown, Hub Pages.) Until now a land bridge has connected Britain to Ireland, roughly from the south-eastern tip of the latter to south-western England.Animals, including the Giant Deer, and the hunter-gatherers who have followed them are now cut off.The land bridge makes a few more brief appearances as short-term fluctuations interfere with average sea levels before being swallowed up permanently.The most striking feature of pre-Ptolemy Ireland are legends of the island being divided in half between north and south.Post-Ptolemy, the four or five kingdoms with which we are familiar began to appear (Connacht, Laigin, Mide, Munster, and Ulaid), but each of these kingdoms were composed of multiple tribes.The passage tomb there is built around this time according to archaeological estimations, clearly constructed by people who have a sophisticated understanding of the motions of the sun, moon, and stars, thanks to the tomb's alignment and the lunar map found inside it.Gaelic Ireland There exists a very small window through which to view the tribes of Ireland (those which largely pre-date the Roman presence in Britain).
Some tribes were apparently wiped out, while others, such as the Domnonn and Concani/Gangani moved large distances.There were some signs that unity would eventually have come, however.At various points in its early medieval history, from the eighth or ninth centuries onwards, Ireland was nominally united under the high kings (ard ri) and, but for many incursions by Danes, Normans and the Norman-dominated English, Ireland might have developed into a fully unified single kingdom in the same way as England had in the tenth century.Then in the late fourth century, Niall of the Nine Hostages apparently dominated much of Ireland.His offspring, the U Neill, used a descent system to describe themselves, and this appears to have been adopted by most of the island.During the sixth century, Saint Columba followed in the footsteps of the earlier Irish raiders to spread the Celtic Church into Dl Riata (now western Scotland), while in western Wales the Disi settled and helped to form the kingdom of Dyfed.
