SALWA BUGAIGHIF, LIBYAN POLITICAL ACTIVIST: Everything is not easy. But if there is a will, there is a way. We'll have to go to the end.
HASAN: With no specific role, they deal with whatever is thrown at them. Everything from listening to worried fathers whose sons are fighting on the front line to keeping up with the day to day clashes and casualty numbers, to having meetings about health and educational issues in a new, free eastern Libya.
DR. IMAN BUGAIGHIF, LIBYAN POLITICAL ACTIVIST: It consumes a lot, but it's just amazing that we don't feel the time. We come here from morning and we don't feel tired.
HASAN: It's easy to see how crucial they are to the movement. No sooner are they done with one informal hallway meeting, they're pulled into the next one. Even our cameraman struggles to keep up with them, and they are modest.
I. BUGAIGHIF: We're not the heroes. The heroes are the mothers who are encouraging their children to go and fight for freedom. And they know it may be the last time they will see them.
HASAN: These weren't the first women I'd encountered during the last amazing two months. The revolution has spread like a fever across the Middle East. In Egypt, women, especially young women, have helped lead the uprising, blogging, tweeting, organizing, making their views heard any way they can, for the first time in full partnership with men.
UNIDENTIFIED FEMALE: We will not give up.
HASAN: 24-year-old Gigi Ibrahim is one of the faces of the Egyptian revolution. An outspoken activist, Ibrahim was shot in the back with a rubber bullet during the protests in Tahrir Square. That didn't stop her.
GIGI IBRAHIM, EGYPTIAN POLITICAL ACTIVIST: I was more determined, I think. This is what helped the revolution. People died for this. Hundreds were willing to die for this to continue and succeed. And this is the price of democracy and freedom.
HASAN: Worried about her safety, her family begged her not to demonstrate.
AZIZA IBRAHIM, GIGI'S SISTER: All my friends, all my family have been calling me because I'm the elder sister to her, oh, my God, don't let her go, don't let her go.
G. IBRAHIM: My aunt now is intervening.
UNIDENTIFIED FEMALE (through translator): You are a bunch of kids who made a revolution and destroyed the--
G. IBRAHIM: I'm not the Egyptian people--
The swarms of pro-Mubarak supporters are trying to infiltrate Tahrir Square.
HASAN: But Ibrahim was on a mission to change her future and those of others. She worked tirelessly, appearing on every news channel possible, updating followers on Twitter and Facebook, galvanizing other Egyptians.
G. IBRAHIM: I told you this day was coming. You didn't believe me.
HASAN: Rallying them to come out in big numbers to fight for their freedom.
And it worked. Not only did she play a part in changing the regime, she changed perceptions of what it means to be a woman in the Arab world.
G. IBRAHIM: This is an historical moment in the revolution. My sister is here. And that says a lot.
A. IBRAHIM: That's a revolution by itself.
HASAN: For this week, Lama Hasan, ABC News, Benghazi, Libya.
AMANPOUR: And the big question, how much will the newly empowered women of the Middle East shape their emerging democracies? It's something the United States, as well as much of the world, is looking at closely.
