The United States and the Soviet Union emerged as rival superpowers in the aftermath of World War II . During the Cold War , the two countries confronted each other indirectly in the arms race , the Space Race , proxy wars , and propaganda campaigns. The purpose of this was to stop the spread of communism. In the 1960s, in large part due to the strength of the Civil Rights Movement, another wave of social reforms was enacted by enforcing the constitutional rights of voting and freedom of movement to African-Americans and other racial minorities. The Cold War ended when the Soviet Union was officially dissolved in 1991, leaving the United States as the world's only superpower.

After the Cold War, the United States began focusing on modern conflicts in the Middle East and nuclear programs in North Korea . The beginning of the 21st century saw the September 11 attacks by Al-Qaeda in 2001, which was later followed by the U.S.-led wars in Iraq and Afghanistan . In 2008, the United States had its worst economic crisis since the Great Depression , which was followed by slower-than-usual rates of economic growth during the 2010s.

The pre-Columbian era incorporates all period subdivisions in the history and prehistory of the Americas before the appearance of significant European influences on the American continents, spanning the time of the original settlement in the Upper Paleolithic period to European colonization during the early modern period . While technically referring to the era before Christopher Columbus ' voyages of 1492 to 1504, in practice the term usually includes the history of American indigenous cultures until they were conquered or significantly influenced by Europeans, even if this happened decades or even centuries after Columbus' initial landing.

Photography as a medium is less than 200 years old. But in that brief span of history, it has evolved from a crude process using caustic chemicals and cumbersome cameras to a simple yet sophisticated means of creating and sharing images instantly. Discover how photography has changed over time and what cameras look like today.

By the mid-1600s, with the invention of finely crafted lenses, artists began using the camera obscura to help them draw and paint elaborate real-world images. Magic lanterns, the forerunner of the modern projector, also began to appear at this time. Using the same optical principles as the camera obscura, the magic lantern allowed people to project images, usually painted on glass slides, onto large surfaces. They soon became a popular form of mass entertainment.

German scientist Johann Heinrich Schulze conducted the first experiments with photo-sensitive chemicals in 1727, proving that silver salts were sensitive to light.

History (from Greek ἱστορία , historia , meaning "inquiry, knowledge acquired by investigation") [2] is the study of the past as it is described in written documents. [3] [4] Events occurring before written record are considered prehistory . It is an umbrella term that relates to past events as well as the memory, discovery, collection, organization, presentation, and interpretation of information about these events. Scholars who write about history are called historians .

History can also refer to the academic discipline which uses a narrative to examine and analyse a sequence of past events, and objectively determine the patterns of cause and effect that determine them. [5] [6] Historians sometimes debate the nature of history and its usefulness by discussing the study of the discipline as an end in itself and as a way of providing "perspective" on the problems of the present. [5] [7] [8] [9]

Ancient influences have helped spawn variant interpretations of the nature of history which have evolved over the centuries and continue to change today. The modern study of history is wide-ranging, and includes the study of specific regions and the study of certain topical or thematical elements of historical investigation. Often history is taught as part of primary and secondary education, and the academic study of history is a major discipline in university studies.
