The swastika (卐 or 卍) is an ancient religious and cultural symbol, predominantly found in various Eurasian cultures, as well as some African and American ones. In the West it is more widely recognized as a symbol of the German Nazi Party who appropriated it from Asian cultures starting in the early 20th century. The appropriation continues with its use by neo-Nazis around the world. The swastika never stopped being used as a symbol of divinity and spirituality in Indian religions, including Hinduism, Buddhism, and Jainism. It generally takes the form of a cross, the arms of which are of equal length and perpendicular to the adjacent arms, each bent midway at a right angle.

The word swastika comes from Sanskrit: स्वस्तिक, romanized: svastika, meaning 'conducive to well-being'. In Hinduism, the right-facing symbol (clockwise) (卐) is called swastika, symbolizing surya ('sun'), prosperity and good luck, while the left-facing symbol (counter-clockwise) (卍) is called sauvastika, symbolising night or tantric aspects of Kali. In Jain symbolism, it represents Suparshvanatha – the seventh of 24 Tirthankaras (spiritual teachers and saviours), while in Buddhist symbolism it represents the auspicious footprints of the Buddha. In several major Indo-European religions, the swastika symbolises lightning bolts, representing the thunder god and the king of the gods, such as Indra in Vedic Hinduism, Zeus in the ancient Greek religion, Jupiter in the ancient Roman religion, and Thor in the ancient Germanic religion. The symbol is found in the archeological remains of the Indus Valley Civilisation and Samarra, as well as in early Byzantine and Christian artwork.

Although used for the first time as a symbol of international antisemitism by far-right Romanian politician A. C. Cuza prior to World War I, it was a symbol of auspiciousness and good luck for most of the Western world until the 1930s, when the German Nazi Party adopted the swastika as an emblem of the Aryan race. As a result of World War II and the Holocaust, in the West it continues to be strongly associated with Nazism, antisemitism, white supremacism, or simply evil. As a consequence, its use in some countries, including Germany, is prohibited by law. However, the swastika remains a symbol of good luck and prosperity in Hindu, Buddhist and Jain countries such as Nepal, India, Thailand, Mongolia, Sri Lanka, China and Japan, and by some peoples, such as the Navajo people of the Southwest United States. It is also commonly used in Hindu marriage ceremonies and Dipavali celebrations.
