Swastika
The swastika is an ancient symbol that emerged independently among many cultures. Before the 20th century, its use was almost always benign, and it is still a common religious symbol across Asia associated with good fortune. However, it was adopted in the early 20th century by German right-wing movements and used as the symbol for the Nazi Party beginning in 1920. Since then, the swastika has become perhaps the most notorious hate symbol in Western culture.
