After four years in Jerusalem, his father brought him back to Cairo, where an older sister took care of him and his siblings. Arafat never mentions his father, who was not close to his children. Arafat did not attend his father's funeral in 1952.

In Cairo, before he was seventeen Arafat was smuggling arms to Palestine to be used against the British and the Jews. At nineteen, during the war between the Jews and the Arab states, Arafat left his studies at the University of Faud I (later Cairo University) to fight against the Jews in the Gaza area. The defeat of the Arabs and the establishment of the state of Israel left him in such despair that he applied for a visa to study at the University of Texas. Recovering his spirits and retaining his dream of an independent Palestinian homeland, he returned to Faud University to major in engineering but spent most of his time as leader of the Palestinian students.

He did manage to get his degree in 1956, worked briefly in Egypt, then resettled in Kuwait, first being employed in the department of public works, next successfully running his own contracting firm. He spent all his spare time in political activities, to which he contributed most of the profits. In 1958 he and his friends founded Al-Fatah, an underground network of secret cells, which in 1959 began to publish a magazine advocating armed struggle against Israel. At the end of 1964 Arafat left Kuwait to become a full-time revolutionary, organising Fatah raids into Israel from Jordan.

It was also in 1964 that the Palestine Liberation Organisation (PLO) was established, under the sponsorship of the Arab League, bringing together a number of groups all working to free Palestine for the Palestinians. The Arab states favoured a more conciliatory policy than Fatah's, but after their defeat by Israel in the 1967 Six-Day War, Fatah emerged from the underground as the most powerful and best organised of the groups making up the PLO, took over that organisation in 1969 when Arafat became the chairman of the PLO executive committee. The PLO was no longer to be something of a puppet organisation of the Arab states, wanting to keep the Palestinians quiet, but an independent nationalist organisation, based in Jordan.

Arafat developed the PLO into a state within the state of Jordan with its own military forces. King Hussein of Jordan, disturbed by its guerrilla attacks on Israel and other violent methods, eventually expelled the PLO from his country. Arafat sought to build a similar organisation in Lebanon, but this time was driven out by an Israeli military invasion. He kept the organization alive, however, by moving its headquarters to Tunis. He was a survivor himself, escaping death in an airplane crash, surviving any assassination attempts by Israeli intelligence agencies, and recovering from a serious stroke.

His life was one of constant travel, moving from country to country to promote the Palestinian cause, always keeping his movements secret, as he did any details about his private life. Even his marriage to Suha Tawil, a Palestinian half his age, was kept secret for some fifteen months. She had already begun significant humanitarian activities at home, especially for disabled children, but the prominent part she took in the public events in Oslo was a surprise for many Arafat-watchers. Since then, their daughter, Zahwa, named after Arafat's mother, has been born.

The period after the expulsion from Lebanon was a low time for Arafat and the PLO. Then the intifada (shaking) protest movement strengthened Arafat by directing world attention to the difficult plight of the Palestinians. In 1988 came a change of policy. In a speech at a special United Nations session held in Geneva, Switzerland, Arafat declared that the PLO renounced terrorism and supported "the right of all parties concerned in the Middle East conflict to live in peace and security, including the state of Palestine, Israel and other neighbours".

The prospects for a peace agreement with Israel now brightened. After a setback when the PLO supported Iraq in the Persian Gulf War of 1991, the peace process began in earnest, leading to the Oslo Accords of 1993.

This agreement included provision for the Palestinian elections which took place in early 1996, and Arafat was elected President of the Palestine Authority. Like other Arab regimes in the area, however, Arafat's governing style tended to be more dictatorial than democratic. When the right-wing government of Benjamin Netanyahu came to power in Israel in 1996, the peace process slowed down considerably. Much depends upon the nature of the new Israeli government, which will result from the elections to be held in 1999.
