List of time periods The categorization of time into discrete named blocks is called periodization. This is a list of such named time periods as defined in various fields of study. Major categorization systems include cosmological (concerning the various time periods in the origin and evolution of our universe), geological (concerning time periods in the origin and evolution of earth ) and historical (concerning time periods in the origin and evolution of mankind). Human time periods These can be divided broadly into prehistorical (before history began to be recorded) and historical periods (when written records began to be kept). Prehistorical periods In archaeology and anthropology, human prehistory is subdivided around the three-age system. The dates for each age can vary by region. Historical periods Full article ▸
A History of the World - Location - Europe This Isn't the Speech I Expected to Give Today This isn't the speech I expected to give today. I intended something else. For the last several years I've been taking every possible opportunity to talk about the soul of democracy. 'Something is deeply wrong with politics today,' I told anyone who would listen. And I wasn't referring to the partisan mudslinging, or the negative TV ads, the excessive polling or the empty campaigns. This wasn't something I came to casually, by the way. But I'm not the same man I was six weeks ago. For this generation, that moment will be September 11th, 2001-the worst act of terrorism in our nation's history. This is their real target, to turn our imaginations into Afghanistans, where they can rule by fear. This summer our daughter and son-in-law adopted a baby boy. None of us is spared. Returning from Washington on the train last week, I looked up and for the first time in days saw a plane in the sky. I wish I could find the wisdom in this. But I haven't been ready for reflection. He's right.
Elizabeth I: An Overview (BBC) Stone Age Timelines Human prehistory and the Stone Age… a timeline critique (4th edition - October 2012) by A.O. Kime for information on 'renting' this article, see Rent-a-Article In the 1820’s, in order to address the prehistory of mankind more clearly, it was thought necessary to divide it into time periods, thus a ‘three-age’ system of the (1) Stone Age, (2) Bronze Age and (3) Iron Age was adopted. While this system is still more-or-less in common use today, refinements were inevitable and the Stone Age, so immensely long, was later subdivided into three major periods as follows: Paleolithic (c 2,000,000 – c 10,000 B.C.) The Paleolithic time period is by far the longest, beginning some (circa) two million years ago to coincide with the first evidence of toolmaking and ending around 10,000 B.C. to coincide with the end of the last ice age (Pleistocene epoch). • Lower Paleolithic (two million – 100,000 B.C Mesolithic (c 10,000 – c 5,500 B.C.) Neolithic (c 5,500 – c 2,500 B.C.) Stone Age observations A.O.
Geography Strikes Back Queen Elizabeth 1 The first Queen Elizabeth, whose name has become a synonym for the era which she dominated (1558-1603), was born in 1533 to Henry VIII and Anne Boleyn. Called "Gloriana" by Edmund Spenser in "The Faerie Queene", Elizabeth's deft politicalskills and strong personal character were directly responsible for putting England (at the time of her accession in 1558 a weak, divided backwater far outside the mainstream of European power and cultural development) on the road to becoming a true world economic and political power and restoring the country's lost sense of national pride. Although she entertained many marriage proposals and flirted incessantly (her closest brush with marriage came with Robert Dudley, earl of Leicester), she never married or had children. Her first order of business was to eliminate religious unrest. The situation with Mary Queen of Scots was most vexing to Elizabeth. As they say, the rest is history. Elizabeth was a master of political science.
Historical Network Research Antietam, the Civil War's deadliest day: On the battle’s 150th anniversary, remembrances from Oliver Wendell Holmes, William McKinley, Rutherford B. Hayes, Clara Barton, and other survivors A misty rain shrouded Antietam Creek as Pvt. David L. Thompson and other footsore soldiers from the 9th New York Infantry took their places on the Union line and unrolled their blankets. “We sat down and watched for a while the dull glare on the sky of the Confederate campfires behind the hills,” Thompson wrote. Two great armies were steeling themselves for what would become the deadliest one-day battle in American history. North and South fought in the open at close quarters—usually no more than 300 yards apart—with no protective earthworks to soften the blows. The clash was one of the worst days in a long war known for its carnage. The morning of Sept. 17 opened with a tremendous crash as opposing batteries traded blows across the creek. To reach the church, Hooker’s troops had to cross open ground, plunge into a thickly planted cornfield and emerge on the far side. To stiffen his lines, Jackson summoned Brig. Union Maj. Alexander Gardner/Library of Congress.
