The Indus Valley civilization, one of the oldest in the world, dates back at least 5,000 years. Aryan tribes from the northwest infiltrated onto Indian lands about 1500 BC; their merger with the earlier Dravidian inhabitants created the classical Indian culture. Arab incursions starting in the 8th century and Turkish in the 12th were followed by those of European traders, beginning in the late 15th century. | The Indus Valley civilization, one of the oldest in the world, dates back at least 5,000 years.
