Corazon Aquino, the unassuming widow whose "people power" revolution toppled a dictator, restored Philippine democracy and inspired millions of people around the world, died early this morning after a battle with colon cancer. She was 76.

Widely known as "Cory," the slight, bespectacled daughter of a wealthy land-owning family served as president of the Philippines from 1986 to 1992, the first woman to hold that position.

She was widowed in 1983 when her husband, political opposition leader Benigno S. Aquino Jr., was assassinated upon his return from exile to lead a pro-democracy movement against authoritarian President Ferdinand Marcos. It was a popular revolt against Marcos following a disputed election that later enabled Corazon Aquino to assume power.

In her six tumultuous years in office in the fractious, strife-torn, disaster-prone archipelago, Aquino resisted seven coup attempts or military revolts, battled a persistent Communist insurgency and grappled with the effects of typhoons, floods, droughts, a major earthquake and a devastating volcanic eruption. Her tribulations earned her the nickname "Calamity Cory."

As she dealt with those challenges, she took pride in restoring democratic institutions that had been gutted under Marcos' 20-year-rule. And she presided over a series of relatively free elections, the dismantling of monopolies and an initial spurt of economic growth.

Her administration failed to make much headway in alleviating poverty, stamping out corruption or delivering basic services. It bequeathed her successor an economic slump marked by protracted costly power failures that reflected inattention to the country's energy needs.

Despite the turmoil that dogged her presidency, Aquino oversaw the first peaceful transfer of power in the Philippines in 26 years. She returned to private life with relief, although she remained politically active.

She played a role in popular protests that led to the ouster of President Joseph Estrada in January 2001. She initially supported his successor, Gloria Macapagal Arroyo, but increasingly turned against her in recent years, siding with opponents who accused Arroyo of vote-rigging and corruption.

Aquino's transition from housewife to president to respected elder stateswoman and democracy advocate represented a phenomenal metamorphosis for a self-effacing mother of five who, before being drafted to take on Marcos in 1986, had never before run for public office.

In a last bit of symbolism to show she was returning to private life as an ordinary citizen, she drove away from her successor's inauguration in a white Toyota she had purchased, shunning the government Mercedes available to her.
