background of pakistani culture

Pakistan has a cultural and ethnic background going back to the Indus Valley Civilization, which existed from 2800–1800 B.C., and was remarkable for its ordered cities, advanced sanitation, excellent roads, and uniquely structured society. Pakistan has been invaded many times in the past, and has been occupied and settled by many different peoples, each of whom have left their imprint on the current inhabitants of the country. Some of the largest groups were the 'Aryans', Greeks, Scythians, Persians, White Huns, Arabs, Turks, Mongols, Afghans, Buddhists and other Eurasian groups, up to and including the British, who left in the late 1940s.
