Swastika is the most famous symbol in the world. The symbol of Swastika is rooted in Vedic religion of Hinduism and regarded as symbol of auspiciousness.
Apart from India, the ancient land of Hinduism, the  culture of using Swastika has been recorded to have existed in ancient findings in Europe, Middle East and the Americas.
Swastika has been regarded in high altars in Hinduism and other religions with parctices similar to Hinduism like Paganism, Odinism, Zorastrianism and Rodnoverism aka Peterburgian Vedism aka Slavic Vedism.
It will be safe to say that many other ancient religions follow the belief system, practices and symbols similar to Hinduism.
The revelation of Swastika being spotted in various variants at different ancient sites around the globe viz Mesopotamian, Indus Valley, Maya, Sumerian, China, India, Egypt et al suggest Hindu faith being followed in the ancient pre-Christian era.
This supports the Quote from Shrimad Bhagwat Geeta, where Lord Shri Krishna says Vasudev Kutumbukam meaning entire world  is my family.
Due to the Nazi ideology misusing Swastika, the followers are subjected to stigmatization and Hindus have been subjected to hate crimes misinterpreting them to be Nazis, while in reality they are worshipping the symbol with intention for prosperity to all, wellness to all.
The cultures that worshipped it submitted to the demands of the antagonists due to degrading or lost sense of ancestralism and have abolished Swastika from their national and cultural symbology. From being insignia of Coca-Cola products, Boy Scouts� and Girls� Club materials and even American military uniform, it has been the insignia of the Finnish Air Force until 2020.
