The tall, lean, rich man's son could have spent his life lounging about Saudi Arabia in luxury. Instead, Osama bin Laden chose to kill.
As a young man, he shot at Soviet invaders in Afghanistan. In middle age, he turned his wrath and far-reaching resources against the United States — the superpower he saw as spoiler of his homeland's sacred cities.
By the time of his death, his was the face of terrorism.
President Barack Obama announced from the White House Sunday that bin Laden had been killed by a special operation in Pakistan. His body is in the custody of U.S. officials.
In the mind of the American public, bin Laden was often seen as the person whose sinister creativity resulted in atrocities committed in the name of Islamic fanaticism. In truth, experts said he served more as idol and motivator to militant Muslims who were convinced that America's support of Israel and its presence in Saudi Arabia — home to the holy places of Medina and Mecca — demanded bloodshed.
Bin Laden's charismatic ways, his fortune and his ability to extract money from other wealthy Islamic extremists gave sophistication and firepower to a terrorism campaign that had been lurching from one haphazard car bombing to the next.
Without bin Laden, the terrorist hijackers may well have stayed home to wage their protests, never to imagine unleashing attacks in the United States.
"I was the most optimistic" that destruction and death at the World Trade Center would be massive, bin Laden declared with characteristic hubris in a videotape.
Once seen by Washington as a freedom fighter, bin Laden launched the militant organization al-Qaida during the Soviet Union's invasion of Afghanistan. Over the years, al-Qaida provided training to as many as 11,000 men who passed through its camps in Afghanistan. Al-Qaida is now thought to have secret soldiers in four dozen countries.
Federal authorities have implicated bin Laden in some of the bloodiest crimes of the past decade: the 1993 bombing of the World Trade Center. The 1998 bombings of U.S. embassies in Tanzania and Kenya. The 2000 bombing of the USS Cole in Yemen.
As for the Sept. 11, 2001, atrocities, the terrorist leader made clear his satisfaction, if not his responsibility.
The so-called smoking-gun videotape of bin Laden meeting with supporters never caught him saying outright that he ordered the attacks. But, clearly, here was a man who relished whatever role he played in the murder of American civilians.
He boasted with a grin: "We calculated in advance the number of … enemy who would be killed."
He was born Osama bin Muhammad bin Awad bin Laden in Jiddah, Saudi Arabia. Most accounts placed his birth in 1957, although he suggested different years to different interviewers.
He reportedly was the 17th of Muhammad bin Laden's 50-plus children. He was also said to be his Syrian mother's only child, an indication she was among the patriarch's least-favored wives.
Legend had it that Muhammed bin Laden was illiterate when he emigrated on foot from his homeland of Yemen to Saudi Arabia. Once there he slowly cobbled together a construction business that, with the eventual help of his sons, grew to a $5 billion enterprise.
Osama bin Laden's early years were comfortable — a far cry from the angry lives of many young radicals whom his terrorist camps later trained. A devout Sunni Muslim, he attended Saudi Arabian schools and studied economics and management in college.
His family's business won important contracts to rebuild mosques. But being a younger son, bin Laden did not figure prominently in the family hierarchy or its decisionmaking.
The 1979 Soviet invasion of Afghanistan upended what could have been a life of ease for the man in his early 20s.
Galvanized by what he saw as an epic battle between Muslims and godless communists, he joined the Afghan resistance. He is thought to have used some of his family's wealth to import weapons and to recruit Muslims from Egypt, Turkey, Lebanon — in time, even the United States.
His fighters were backed by American and Saudi tax dollars and advised by the U.S. Central Intelligence Agency.
By the mid 1980s, the guerrilla commander had bonded with the Egyptian Islamic Jihad, a terrorist group that helped to assassinate President Anwar Sadat. One of its key leaders, Ayman al-Zawahri, would have a strong influence and eventually be a brother-in-arms.
In the late 1980s, bin Laden began to tell followers of a vision that had come to him of a global jihad to be waged by Muslims around the world.
So evolved al-Qaida, Arabic for "the base."
After the Soviet withdrawal from Afghanistan in 1989, bin Laden returned to Saudi Arabia a hero, working briefly in the family business. A sought-after speaker, he also released a quarter-million cassette tapes that outlined a new enemy in his sights. "When we buy American goods," he said in one tape, "we are accomplices in the murder of Palestinians. … The United States uses that money to send a billion (dollars) a year to Israel."
His anti-Western rhetoric intensified in 1990, when Saudi rulers allowed American military personnel to use the birthplace of Islam as a staging ground for the Persian Gulf War. Bin Laden cast it as a desecration of a holy site. He accused the Saudi royal family of being as vile as the Americans.
His radical reading of Koran scripture called for violence to eradicate from Islam all traces of secular culture — from pop music to modern fashions to U.S. soldiers.
Saudi Arabia expelled bin Laden in 1991 because of his anti-government activities. He wound up in Sudan, which expelled him in 1996 under pressure from American and Saudi diplomats.
What ostensibly had begun as a battle to liberate Afghanistan and Islam's three holiest places — Mecca, Medina and Jerusalem — would soon become a holy war, a jihad, against the United States.
