In the early 20th century, Western European countries had evolved into industrialized societies. Some people began to put "Naked Beauty" into practice. They started to allow nudity on certain beaches or in some sports activities.

After World War I, people drew lessons from the barbaric and cruel war, and started to pay more attention to the pursuit of a better life and nature. In the meantime, people felt increasing pressure from the industrial society that shackled their individuality, and they began to revere a return to the natural state of mankind.

Various kinds of public nudity began to emerge and some countries established nudism camps, where people could fully enjoy being in their natural state. This was also a way to express their rebellion and confrontation with industrial society.

The essential difference between nudism and the erotic nude is that nudists or naturists are not deliberately showing their naked body to anyone, they do not chase commercial profits. They shed their clothes without any economic motive.
