Timeline: 1979 - Travels to Afghanistan to join the jihad (holy war) against the Soviet Union. He remains there for a decade, using construction equipment from his family's business to help the Muslim guerrilla forces build shelters, tunnels and roads through the rugged Afghan mountains, and at times taking part in battle.
1988 - Bin Laden founds Al-Qaeda (or "the base").
1989 - The Soviet Union withdraws from Afghanistan. Bin Laden returns to Saudi Arabia to work for the family construction firm, the Bin Laden Group.
August 7, 1990 - Following the Iraqi invasion of Kuwait, U.S. troops arrive in Saudi Arabia. Bin Laden is outraged at their presence, and soon begins to target the United States for its presence on Saudi soil near the Muslim holy sites of Mecca and Medina.
1991 - Bin Laden is expelled by the Saudi regime. Eventually he and his followers relocate to Sudan, taking assets that had grown to an estimated $250 million, according to some officials (others estimate a much lower value). There, al Qaeda begins to evolve into a terror network.
December 1992 - U.S. forces land in Somalia, spearheading a U.N.-authorized humanitarian plan to bring in famine relief supplies. Part of their challenge is disarming the various warlords who control the country. Prosecutors charge that bin Laden threw himself into the midst of this conflict, sending some of his followers to Somalia to train the warlords to fight the U.S. troops.
February 26, 1993 - A bomb explodes at the World Trade Center in New York, killing six and wounding hundreds. Six Muslim radicals, who U.S. officials suspect have links to bin Laden, are eventually convicted for the bombing. Bin Laden is later named along with many others as an unindicted co-conspirator in that case.
October 1993 - Eighteen U.S. servicemen, who are part of a humanitarian mission to Somalia, die in an ambush in Mogadishu. Bin Laden later says that some Arab Afghans were involved in the killings and calls Americans "paper tigers" because they withdrew from Somalia shortly after the soldiers' deaths.
1994 - The Saudi government officially strips bin Laden of his citizenship, freezing all remaining assets he has in the country. His family disowns him as well. Bin Laden is the target of an assassination attempt, so he strengthens his personal security detail. In the following months, officials believe he funds and directs a series of attacks, including a failed attempt to kill Egyptian president Hosni Mubarak and a 1995 suicide bombing at the Egyptian embassy in Pakistan. Authorities now believe that this was the early days of a growing alliance between bin Laden and other militant Islamic groups, above all with the Egyptian Islamic Jihad and its leader, Ayman al- Zawahiri.
1995 - A truck bombing at a military base in Riyadh, Saudi Arabia, kills five Americans and two Indians.
1996 - Sudan expels Bin Laden from the country. He moves with his children and wives to Afghanistan where he receives harbor from the fundamentalist Taliban. The United States indicts bin Laden on charges of training the people involved in the 1993 attack that killed 18 U.S. servicemen in Somalia.
August 23, 1996 - Bin Laden declares a jihad, or holy war, against U.S. forces.

1997 - In his first interview with Western media, bin Laden tells Peter Bergen that the United States is "unjust, criminal and tyrannical." "The U.S. today, as a result of the arrogant atmosphere, has set a double standard, calling whoever goes against its injustice a terrorist," he said in the same interview. "It wants to occupy our countries, steal our resources, impose on us agents to rule us." Bin Laden also tells Bergen that "Arab holy warriors" trained in Afghanistan had banded with Somali Muslims in October 1993 to kill 18 U.S. soldiers in a bloody battle on the streets of Mogadishu, Somalia. He says, "The U.S. today has set a double standard, calling whoever goes against its injustice, a terrorist. It wants to occupy our countries, steal our resources, impose agents on us to rule us, and then wants us to agree to all this. If we refuse to do so, it says we are terrorists."
February 1997 - According to court documents, bin Laden orders the militarization of the East African cell of Al Qaeda, a move that culminated in the bombing of the U.S. embassies in Kenya and Tanzania on August 7, 1998, eight years to the day after U.S. troops landed in the Saudi kingdom.
