The swastika has an extensive history. It was used at least 5,000 years before Adolf Hitler designed the Nazi flag. The word swastika comes from the Sanskrit svastika, which means “good fortune” or “well-being.” The motif (a hooked cross) appears to have first been used in Neolithic Eurasia, perhaps representing the movement of the sun through the sky. To this day it is a sacred symbol in Hinduism, Buddhism, Jainism, and Odinism. It is a common sight on temples or houses in India or Indonesia. Swastikas also have an ancient history in Europe, appearing on artifacts from pre-Christian European cultures.
In the beginning of the twentieth century the swastika was widely used in Europe. It had numerous meanings, the most common being a symbol of good luck and auspiciousness. However, the work of Schliemann soon was taken up by völkisch movements, for whom the swastika was a symbol of “Aryan identity” and German nationalist pride.
This conjecture of Aryan cultural descent of the German people is likely one of the main reasons why the Nazi party formally adopted the swastika or Hakenkreuz (Ger., hooked cross) as its symbol in 1920.
