Indus Valley Civilization

Indian civilization at its earliest was a mystery. It appeared in the Indus River Valley, stayed for 1000 years, and vanished mysteriously. Even though recently archeologists have found the civilization, most sites remain relatively uncovered. No names of kings or queens, no records, no literature, no accounts of victories, no evidence whatsoever. However, we do know the Indus Valley was the largest civilization until Persia arose.
