No, contemporary art is any art that is being created "in the now".
Art was created during the stone-ages. Back then they created art for religious purposes, and for communication. That is until they formed language.
the condition of being governed
The essence of art is quiet. Art is created in harmony. We are accustomed to when the art work we're comfortable together.
Sorry, but the term "contemporary" art isn't a movement in art. That means contemporary art of the 1920s is art that was in the process of being created during the 1920s, and contemporary art of today is art that is being created today. To answer your question literally, contemporary art starts now. But I think you may mean when did the idea of modern art come into play. I would say the 1950s are the start of what we call modern art and that it turned into modern art in roughly the 1970s.
Legal requirements aren't governed by the art you study they are governed by the laws where you live which vary widely.
