The Aryan Invasions is a period of time in which the Harrapan civilization was razed and the Indian sub-continent was plunged into an age of very little cultural progression and very long stretches indigenous oppression lasting for thousands of years. It was brought on by successive invasions and harsh oppression of indigenous peoples. Like the history of the Nile Valley, a high civilization located in the Indus Valley was invaded many times over thousands of years, having it's society displaced, it's culture, language and indeed complexion forever changed. It's estimated that throughout 3500 years, and 6 great invasions, upwards of 7 million were killed, and countless others displaced.
Indus Valley Civilization
The Indus Valley Civilization consisted of 3 main groups of people. According to scholar Uthaya Naidu , Approximately 90% were different groups of migrant Afrikan peoples, while 10% were groups of Eastern Asian types. Probably Negrito groups. The first cities of this civilization are thought to have been established around 2600 B.C. in what is now Pakistan and western India. The peoples who built and ruled this civilization belong to the Harappan Culture or Indus Valley Civilization. This civilization thrived at around the same time as the the civilizations of Egypt and Mesopotamia. The cities of the Indus Valley Civilization were well-organized and solidly built out of brick and stone. Their drainage systems, wells and water storage systems were the most sophisticated in the ancient world. They also developed systems of weights and trade. They made jewelery and game pieces and toys for their children. The people of the Indus Valley Civilization also developed a writing system which was used for several hundred years. However, unlike some other ancient civilizations, thus language has yet to be deciphered.
Source of information on Aryan Invasions
The ancient spiritual texts known as the The Rig Veda are also a historical record of what was happening in the Indian Sub-Continent during these thousands of years of invasions and dark ages. One example is in The Rig Veda/Mandala 8/Hymn 87
6. For thou art he, O Indra, who stormeth all castles of the foe, Slayer of Dasyus, man's Supporter, Lord of Heaven.
Daysu is another word for the aboriginal people of India, and the originators of the Harrapa Civilization.
Early Vedic Invasions
The First Aryan Invasion involved the annihilation of the Indus Valley civilization by the hordes of Indra , and the slaughter of an estimated 5 million of its inhabitants. The Indus irrigation system was shattered to permanently destroy agriculture in the region. Sudroid blacks were displaced from all of North India, the survivors retreating to the hill tracts of Central North India
Rig Vedic Invasion ~1500 BCE
The Aryan invasions began with the initial onslaught by northern peoples under the guidance of Indra, who would later be deified to become the king of the Aryan gods. The Aryan hordes swept through the politically stable, and peaceful cities of the Harrapan civilization. Much like the Afrikans of the Nile Valley, they were unaccustomed to such violence and blood-shed, and unable to withstand the sheer number of ferocious invaders, the civilization collapsed into massacres, mayhem and disorder. Directly following these series of invasions, the once self sustained civilization descended into 1000 years of intellectual and developmental stagnation. A period referred to as the Vedic Dark Ages. It's thought that nearly the entire population of Harrapan people were destroyed following the destruction of the Indus irrigation system which allowed great agriculture. This was the first recorded instance of ecological warfare. The remaining survivors would have escaped south, deeper into Sudric controlled lands.
Second Aryan Invasion ~1400 BCE
The second set of invasions was launched from present day Afghanistan, and conquered much deeper into northern India, collapsing the city states around the Ganges river vally. This time the invasion was led by Bharata. This was a continuation of the Rig Vedic Invasions that succeeded in killing and displacing the Sudric remnants of the Harrapan Civilization. This event also changed the complexion of northern Indians.
Late Vedic Invasions
During this period of Vedic Dark Ages (1500 BC - 1000 AD), further waves of Sanscrit speaking Aryans invaded India, further exterminating the native populations of darker skinned Indians.
Third (Krishnaite) Aryan Invasion
Krishna launched the Third Aryan invasion, invading Western India (Gujarat, Rajastan etc.) from Mathura in Aryavarta. He finally established his capital there, Dwarka. He destroyed the surviving traces of the Indus Valley civilization, abducting and raping 16000 low-caste women (`gopis') of the races he exterminated. He was also the engineer of the Mahabharatan Holocaust.
Fourth Aryan Invasion
The Fourth Aryan Invasion occurred in 2 parts: First, the Digvijay Aryan invasions that led to the subjugation of all of India to the Aryan yoke. Second, the Kurukshetra battles. The revolt by the non-Aryans and mixed races led to the terrible Mahabharatan War between the Aryan Pandavas on one side and the mixed race Kauravas and black aboriginals on the other. The Aryan victory enabled them to invade & settle in the Ganges valley and confirmed Aryan dominance. The genocides of this war permanently changed the racial composition of most of India. These wars were some of the most terrible recorded.
DigVijay Aryan Invasions
As per the Mahabharata, all parts of India were subjected and the conquered races vanquished. The Aryans spread across the Vindhya into the Deccan, and eventually comprised the majority of the population in Maharastra. Aryans also annexed Dravidia, but the bulk of the population remeined Dravidian. The prime target of the DigVijay invasions were the Mongoloids, who were now subject to the same genocide that the Semitic Panis and Negroid Dasyus had been during the First Aryan invasion.
Nakulite Aryan Invasion of Western India
Nakul was another ferocious conqueror, destroying several non-Aryan races and indulging in senseless genocide. General Nakhul set out from Panchala with a massive army, and annexed Western India. Many aboriginal black ethnic groups were exterminated, and the remnant Indus Valley people consisting of `Panis' (Phoenicians) and `Asuras' (Assyrians) slaughtered.
The Sahdevan Aryan Invasion of South India
General Sahdev embarked on the invasion of South India with a massive army. He enslaved the nations there to the Aryan yoke, including Dravida itself. Several Dravidian cities were demolished by the Vandal Aryans, and countless Dravidians massacred.
Fifth (Solar) Aryan Invasions
The preceding waves of Aryans were members of the Lunar race (Chandravamsi), including the victors of the Mahabharata & Digvijay Wars. Following this is the invasion by Solar race of Aryans (Suryavamsi). It can be traced as the Solar king Ikshvaku, son of Manu Vaivasvat established his capital at Ayodhya & is the first king of Ayodhya, while his grandson Mithi conquered Mithila, which was named after him. Ikshvaku is in turn descended from Kashyapa `the Caspian', who resided near the Caspian Sea. A clear pattern of migration down the Ganges valley is thus apparent. This movement occurred concordant with the genocidal wars of Parasurama. This sovereign, a Brahmin, resolved to undertake the deliberate extermination of non-Aryans. Parasu Rama was another example of the sea of monsters that descended on India, indulging in unnecessary massacres, whose ultimate aim was the destruction and enslavement of the Sudroids (Dravidians, Adivasis, Dalits).
