History of the United States The date of the start of the history of the United States is a subject of debate among historians. Older textbooks start with the arrival of Christopher Columbus on October 12, 1492 and emphasize the European background of the colonization of the Americas, or they start around 1600 and emphasize the American frontier. In recent decades American schools and universities typically have shifted back in time to include more on the colonial period and much more on the prehistory of the Native Americans.
Prehistoric Ireland The prehistory of Ireland has been pieced together from archaeological and genetic evidence; it begins with the first evidence of humans in Ireland around 12,500 years ago and finishes with the start of the historical record around 400 AD. The prehistoric period covers the Palaeolithic, Mesolithic, Neolithic, Bronze Age and Iron Age societies of Ireland. For much of Europe, the historical record begins when the Romans invaded; as Ireland was not invaded by the Romans its historical record starts later, with the coming of Christianity.
