How did Josef Koudelka document life in Czechoslovakia?

In the context of street photography, Josef Koudelka documented life in Czechoslovakia through two primary, distinct approaches:

• Cultural Documentation: During the early to mid-1960s, Koudelka focused on the Roma people of Czechoslovakia. He spent extended periods living among them, drawn to their music and culture, which resulted in a body of work that captured their nomadic lifestyle and traditions.1
• Political Documentation: In 1968, when Warsaw Pact troops invaded Czechoslovakia, Koudelka captured the ensuing chaos in Prague. To protect himself and his family, he smuggled these images out of the country and published them anonymously under the initials "P.P." (standing for "Prague Photographer"). This series earned him the Robert Capa Gold Medal in 1969.1

Koudelka’s work is recognized for its significant contribution to the medium, placing him among the notable street photographers of the 20th century who operated outside of the United States.2
