Nasser is seen as one of the most important political figures in modern Arab history and politics. Under his leadership, Egypt nationalized the Suez Canal and a lot of other industries, and became important in stopping imperialism in the Arab World and Africa. He was also important in starting the Non-Aligned Movement. Nasser's version of pan-Arabism, which is often called ""Nasserism"", was very popular in the Arab world during the 1950s and 1960s. Even after the Israeli victory over the Arab armies in the Six-Day War damaged the way the public saw him, many Arabs still view Nasser as a symbol of Arab dignity and freedom.
