Raising the Flag on Iwo Jima is a historic photograph taken on  February 23, 1945, by Joe Rosenthal. It depicts five United States  Marines and a U.S. Navy corpsman raising the flag of the United States  atop Mount Suribachi during the Battle of Iwo Jima in World War II.
The photograph was extremely popular, being reprinted in thousands of  publications. Later, it became the only photograph to win the Pulitzer  Prize for Photography in the same year as its publication, and  ultimately came to be regarded as one of the most significant and  recognizable images of the war, and possibly the most reproduced  photograph of all times.
