(CNN) -- She is small but only in physical stature. Aung San Suu Kyi is the very embodiment of Myanmar's long struggle for democracy.
The 66-year-old human rights icon defied Myanmar's authoritarian military junta with her quiet demeanor and grace when she spent 15 of 21 years under house arrest for her unending opposition to authoritarian rule in Myanmar.
By the time she was freed in November 2010, she had become, perhaps, the world's most recognizable political prisoner. She was awarded the 1991 Nobel Peace Prize for her non-violent struggle for democracy and human rights.
Over the past year, Suu Kyi has met repeatedly with Myanmar's President Thein Sein and the country's minister for labor and for social welfare, relief and resettlement, Aung Kyi.
Now, she will participate in Myanmar's next elections, Nyan Win, the spokesman for her National League for Democracy, said Friday. Her National League for Democracy announced earlier Friday that it planned to re-register as a political party and participate in all future parliamentary elections.
During her captivity, she lived quietly by herself at her disintegrating Inya Lake villa in Yangon (the former capital, also known as Rangoon), accompanied solely by two maids.
She had little outside human contact except for visits from her doctor.
Sometimes, though, she was able to speak over the wall of her compound to her supporters, never once tiring of her crusade to break down the tyranny of dictatorship in her beloved homeland of Burma, the alternate name for Myanmar.
Known as the "lady" in Myanmar, Suu Kyi has been compared to former South African President Nelson Mandela, who spent a chunk of his life in jail for fighting apartheid.
In an interview with CNN several years ago, Suu Kyi, in fact, likened Myanmar's plight to South Africa's former brutal race-based system.
"It's a form of apartheid," she said. "In Africa, it was apartheid based on color. Here, it is apartheid based on ideas. It is as though those who want democracy are somehow of an alien inferior breed and this is not so."
The daughter of Gen. Aung San, a hero of Burmese independence, Suu Kyi spent much of her early life abroad, going to school in India and at Oxford University in England.
She never sought political office. Rather, leadership was bestowed upon her when she returned home in 1988 after her mother suffered a stroke.
Journey into politics
During her visit, a student uprising erupted and spotlighted her as a symbol of freedom. When Suu Kyi's mother died the next year, Suu Kyi vowed that just as her parents had served the people of Burma, so, too, would she.
In her first public speech, she stood before a crowd of several hundred thousand people with her husband, Michael Aris, and her two sons and called for a democratic government.
"The present crisis is the concern of the entire nation," she said. "I could not, as my father's daughter, remain indifferent to all that was going on. This national crisis could, in fact, be called the second struggle for independence."
She won over the Burmese people. One of them was Nyo Ohn Myint, who participated in the 1988 protests as a college professor and now serves as one of the leaders in Suu Kyi's National League for Democracy.
"She is more than her father's daughter," he told CNN. "She has proven that she can bring together the Burmese people."
In 1989, the military regime threw her in jail. But even with Suu Kyi sitting behind bars, her party won the elections the following year by a landslide, gaining 82 percent of the seats in parliament.
The regime ignored the results of the vote and Senior Gen. Than Shwe continued to impose numerous terms of house arrest on her. Suu Kyi, meanwhile, became the recipient of several human rights prizes and was awarded the Nobel Peace Prize in 1991.
Over the years, Suu Kyi repeatedly challenged the junta and discouraged foreign investment in Myanmar. In one incident in 1998, soldiers prevented her from leaving Yangon. But Suu Kyi refused to turn back and was detained in her minivan for almost two weeks. The ordeal left her severely dehydrated, but was typical of her almost stubborn determination.
Myint described her as energetic but humble. And a good listener.
"That's a skill I barely see in other people," Myint said.
She has remained a devoted Buddhist who from the beginning admired the principles on non-violence and civil disobedience espoused by India's Mahatma Gandhi, Myint said.
Over the years, Suu Kyi has made clear her devotion to bringing democracy to Myanmar. She has spoken of her separation from her loved ones as the sacrifice she chose to make for the freedom of her country.
Her dying husband petitioned the Myanmar authorities to allow him to visit his wife. He had last seen her in 1995, but his request was rejected.
Instead, the junta encouraged Suu Kyi to join her family abroad. But she said she knew that if she left, she would never be allowed to return. Aris died of prostate cancer in March 1999.
Even before they were married, Suu Kyi had penned a letter to Aris professing her love of country.
"I only ask one thing," she wrote, "that should my people need me, you would help me to do my duty by them."
Myint recalled calling her to express his condolences after Aris died in 1999. Suu Kyi was calm on the phone for the four-minute conversation but Myint could tell her heart was breaking.
"Maybe we are good at politics," Suu Kyi told Myint. "But we are bad at family matters."
Life in captivity
Suu Kyi tried to break the monotony of her life by playing her piano, another passion in her life, according to the independent Irrawaddy magazine.
But in time, the piano warped and Suu Kyi turned to painting to fill the void, the magazine reported. One day, maybe, people will see her canvases.
Suu Kyi has also asked her lawyers to bring her books in English and French.
Nobel Prize-winning economist Joseph Stiglitz had been allowed to present her with his book "Globalization and Its Discontent."
In 2007, people defiantly took to the streets to protest rising fuel costs. The demonstrations were seen as a direct challenge to the authority of the government.
The regime answered with a brutal crackdown. Suu Kyi's detention was extended again and again. She appeared gaunt -- and unhappy.
Even when Cyclone Nargis devastated Myanmar in May 2008, Suu Kyi was not allowed to leave her house, though trees were crashing down all around her.
The following year, Myanmar was again propelled into the headlines by a bizarre incident involving an American, John Yettaw, who improvised flippers to swim Inya Lake to Suu Kyi's compound. He said he had received a message from God to do so. Yettaw was arrested, and Suu Kyi was put on trial, charged with harboring Yettaw, and was punished with another 18 months of house arrest.
Some believe that Suu Kyi's stubborn defiance has become an obstacle to progress in Myanmar. But her followers remain ardent in their admiration. She has clung to her dream of democracy, peace and freedom for Myanmar's 50 million impoverished people, they say.
Those simple ideals have greatly complicated one woman's life.
