The Aryan invasions which led to the collapse of the Semito-Negroid Indus Valley civilization plunged India into 2500 years of darkness lasting from 1500 BC to 1000 AD.
The Vedic religion does prescribe that the Aryan race is superior to other races and is hence justified in massacering, looting and ruling over all others. The initial 1000 years, comprising the Vedic Dark Ages (1500 BC - 500 BC) of this episode were the darkest of all. The Early Vedic Dark Ages were marked by two major devastating Aryan invasions:
RigVedic Aryan Invasion (1500 BC)
The initial Aryan onslaught began with the First Aryan invasion under Indra. The barbaric Vedic Aryan hordes swept down into the Indus Valley civilization,
attacking the peace-loving and tolerant Semito-Negroid civilization. Unaccustomed to such violence and blood-shed, and unable to withstand the sheer numbers of ferocious invaders, the civilization collapsed into massacres, mayhem and disorder. Following this calamity, India was plunged into 1000 years of darkness, a period referred to as the Vedic Dark Ages. Virtually the entire native populations of Negroids, Semites and Mongoloids were exterminated. The Indus irrigation system was shattered to permanently destroy agriculture in the region in the first recorded instance of ecological warfare.
Second Aryan Invasion (1400 BC) :
Bharata launched the second Aryan invasion from Afghanistan, and conquered much of the upper Ganges valley. The mayhem and murder continued throughout this period, by the end of which no trace of the Indus Valley civilization was left and Sudroid Blacks had been displaced from all of Northwest India, the survivors retreating to the Ganges valley and Rajasthan.
The massacres perpetuated by the Aryans in India during the 1000 years of the Vedic Dark Ages are unparalleled in history, exceeding the Holocaust of the Jews by the Nazis (which was inspired by the Vedic Aryans), and the slaughter of the South American native populations by the invading Spaniards and Portuguese. Almost all of the 5 million inhabitants of the Indus Valley perished, besides unnumbered others.
