History of the Celts

Source 2: http://www.druidsgrove.com

In general, it is believed by historians that the Celtic people migrated from a common Indo-European homeland somewhere in Eastern Europe and migrated westward. The increasing sophistication, social-stratification, state-building, and so forth, of central Europe gave rise to the periods that that scholars call proto-Celtic and Celtic, or Hallstat 800-500 BCE and La Tene 500-100 BCE. The spread of Celtic culture to the British Isles and to the Atlantic seaboard of Europe took place roughly around 900 BCE. It is safe to assume that there were religious specialists of some kind there at the time, though the notion of "Druids" as a comprehensive religious and intellectual caste doesn't emerge until about 500 BCE or shortly after. 

To correlate that date with other world events, 500 BCE is about the same time that the Buddha is alive in India, Aeschylus and Thespis are writing plays in Greece, Confucius is working for Emperor King-Wang 3rd of China, The Republic of Sicily establishes its first allegiance with Rome, Jeshua is high priest of Palestine, Darius 1st heads the Persian Empire, annually elected archons rule Athens, and Pythagoras is visiting Egypt.

There is good evidence that through their trade routes, and the adoption of customs indigenous to the areas they colonized, that Celtic culture experienced much change and innovation over time. The British Isles may have been visited by humans as early as the retreat of the Ice Age, and has been home to an indigenous neo-lithic (new stone age) culture that contributed much to the development of the Celtic culture at its height of achievement. (Historian Colin Renfrew has, for example, argued that the Celts emerged from an indigenous pre-Celtic Neolithic culture.) 

Here is a brief, and certainly not complete, timeline of the history of the Celtic people, and the islands of Britain and Ireland.
