She is known among Yemenis as “the iron woman” and the “mother of the revolution.” A conservative woman fighting for change in a conservative Muslim and tribal society, Nobel Peace Prize winner Tawakkul Karman has been the face of the mass uprising against the authoritarian regime of President Ali Abdullah Saleh.

The 32-year-old Karman has been an activist for human rights in Yemen for years, but when she was arrested in January, it helped detonate protests by hundreds of thousands demanding the ouster of Saleh and the creation of a democratic government.

When the Nobel announcement was made , Karman was where she has been nearly every day for the past many months: in a protest tent in Change Square, the roundabout in central Sanaa that has been the symbolic epicenter of the revolt.

“This prize is not for Tawakkul, it is for the whole Yemeni people, for the martyrs, for the cause of standing up to (Saleh) and his gangs. Every tyrant and dictator is upset by this prize because it confronts injustice,” she told The Associated Press from her tent as she received congratulations from other activists.

Karman – who shares the prize with Liberian President Ellen Sirleaf Johnson and Liberian peace activist Leymah Gbowee – is the first Arab woman to win the Nobel Peace Prize. With the award, the Nobel committee gave a nod to the Arab Spring, the wave of uprisings that have swept the Middle East, forcing out the leaders of Tunisia, Egypt and Libya.

Like the majority of Yemeni women, Karman once wore the niqab, the conservative Muslim garb that covers the face with a veil and hides the body in heavy robes, leaving only the eyes visible. But last year, she changed to a more moderate headscarf, covering just her hair – she told AP she wanted to be “face to face with my activist colleagues.”When asked about her Hijab By Journalists and how it is not proportionate with her level of intellect and education, she replied:

“Man in early times was almost naked, and as his intellect evolved he started wearing clothes. What I am today and what I’m wearing represents the highest level of thought and civilization that man has achieved, and is not regressive. It’s the removal of clothes again that is regressive back to Ancient times’

She is also a member of Yemen’s opposition Islamic fundamentalist Islah Party, but her participation in the protests brought sharp criticism from conservatives in the party, some of whom denounced her in mosque sermons. Saleh’s regime itself tried to discredit her by spreading a photo of her sitting in a protest tent with a male colleague – with others around them cut out from the picture – seeking to taint her as sinful for being alone with a man.

Women have participated heavily in the protests. The organizers have intentionally sought to cut across tribal lines. And they have resolutely remained peaceful, even as Yemen seems to explode around them. Saleh’s security forces have repeatedly opened fire on protesters. Sanaa and other cities have turned into war zones as regime forces battle with dissident military units and tribal fighters opposed to Saleh.

Her husband, Mohammed al-Nahmi, sitting with her in the tent as he received congratulations, told AP, “This is a prize she deserves. Before she is my wife, she is a colleague, and a companion in the struggle.”

Karman, a mother of three, originally hails from the southern city of Taiz, a city known for its prominent middle class and university intellectuals that has long been a hotbed of opposition to Saleh.
