Explanation:

Turning points are of great significance in periodization as they depict the beginning and end of remarkable events in history. A classical example of a turning point is evident in the the American revolution and the conquer of Britain by America in the war of 1812, and the consequent signing of the Treaty of Ghent. Also, the conquer of Babylon by Medo Persia was a turning point in history. Again, the end of colonialism in Africa was a turning point in history. Another classical example of turning point in history is the action of James Meredith in 1962, that changed the story of the African American, and led to an end to segregation in America.
