 In early 1968, media coverage in the aftermath of the Tet Offensive spurred increased protests in opposition to the Vietnam War, especially among university students.The protests were most prevalent in the United States, and on 17 March, 25,000 demonstrators marched to the American embassy in London's Grosvenor Square and violently clashed with police.Major protests concerning other political issues made international news, such as the March 1968 protests in Poland against their communist government, and the campus uprisings of May 1968 in France.
