Aryans are white people. In modern times, the Nazis mistakenly defined the Germans living in northern Europe and western Europe as Aryans. In fact, the two have nothing to do with each other and are far apart.
Aryans were originally an ancient nomadic people on the grassland in the southern Urals Mountains of Russia, and moved to the plain between the Amu Darya and Syr Darya rivers in Central Asia. These people are called Aryans-Punjabis. In the 14th century BC, Aryans-Punjabis went south to the northwest of the South Asian subcontinent, which is the Aryans mentioned in ancient Indian documents.
They expelled the ancient Dravidians to the south, created the Vedic culture and established the caste system, and brought the Aryan-Punjabi language family to India. In the end, the ancient Aryans and the ancient Dravidians merged into the South Asian subcontinent with unique signs today.
Extended information:
Aryans (whose appearance in northwest India has been confirmed by Rigveda) migrated from outside the Indian subcontinent, or more precisely, arrived at the area they occupied at that time. The last stage of this migration can't be too far away from the time when Rigveda began to be compiled, but at the same time, it must have passed a sufficient period of time.
There are records of Aryan invasion in Indian history. India's four castes are set according to the depth of skin color, among which Brahman and Kashatri are from conquerors: shallow Aryans. The famous Medes and Persians in Persian history are descended from Aryans. Cecian, Sal Machian, Masagatai and Aranta mentioned by historians of ancient Greece and Persia are also Aryans of straight descent.
