WATCH: Jailed Iranian activist Narges Mohammadi wins 2023 Nobel Peace Prize

Imprisoned Iranian activist Narges Mohammadi won the Nobel Peace Prize on Friday in recognition of her tireless campaigning for women's rights and democracy and against the death penalty.

Mohammadi, 51, has kept up her activism despite numerous arrests by Iranian authorities and spending years behind bars.

"This prize is first and foremost a recognition of the very important work of a whole movement in Iran with its undisputed leader, Nargis Mohammadi," said Berit Reiss-Andersen, the chair of the Norwegian Nobel Committee who announced the prize in Oslo.

She said the committee hopes the prize "is an encouragement to continue the work in whichever form this movement finds to be fitting." She also urged Iran to release Mohammadi in time for the prize ceremony on Dec. 10.

For nearly all of Mohammadi's life, Iran has been governed by a Shiite theocracy headed by the country's supreme leader. While women hold jobs, academic positions and even government appointments, their lives can be tightly controlled.

Laws require all women to at least wear a headscarf, or hijab, to cover their hair as a sign of piety. Iran and neighboring Afghanistan remain the only countries that mandate it.

In a statement to The New York Times, Mohammadi said the "global support and recognition of my human rights advocacy makes me more resolved, more responsible, more passionate and more hopeful."

"I also hope this recognition makes Iranians protesting for change stronger and more organized," she added. "Victory is near."

Mohammadi has been imprisoned 13 times and convicted five times, according to Reiss-Andersen. In total, she has been sentenced to 31 years in prison. Mohammadi's most recent incarceration began when she was detained in 2021 after she attended a memorial for a person killed in nationwide protests sparked by an increase in gasoline prices.

She has been held at Tehran's notorious Evin Prison, whose inmates include those with Western ties and political prisoners. Physical and sexual abuse of women in prisons, something Mohammadi has campaigned against both outside of and behind bars, remains endemic.

Mohammadi is the 19th woman to win the Nobel Peace Prize and the second Iranian woman, after human rights activist Shirin Ebadi won the award in 2003

It's the fifth time in the 122-year history of the awards that the peace prize has been given to someone who is in prison or under house arrest. Last year, the top human rights advocate in Belarus, Ales Bialiatski, was among the winners. He remains imprisoned.

Mohammadi was behind bars for the recent protests over the death of 22-year-old Mahsa Amini in police custody. That sparked one of the most intense challenges ever to Iran's theocracy. More than 500 people were killed in a heavy security crackdown while over 22,000 others were arrested.

From behind bars, she contributed an opinion piece for The New York Times.

"What the government may not understand is that the more of us they lock up, the stronger we become," she wrote.

There was no immediate reaction from Iranian state television and other state-controlled media. Some semiofficial news agencies acknowledged Mohammadi's win in online messages, citing foreign press reports.

Before being jailed, Mohammadi was vice president of the banned Defenders of Human Rights Center in Iran. Ebadi, who Mohammadi is close to, founded the center.

In 2018, Mohammadi, an engineer, was awarded the Andrei Sakharov Prize. Earlier this year, PEN America, which advocates for freedom of speech, gave Mohammadi its PEN/Barbey Freedom to Write Award. The organization applauded her win.

The choice "is a tribute to her courage and that of countless women and girls who have poured out into the streets of Iran and faced down one of the world's most brutal and stubborn regimes, risking their lives to demand their rights," PEN America CEO Suzanne Nossel said in a statement.

The Nobel Prizes carry a cash award of 11 million Swedish kronor (about $1 million). Winners also receive an 18-carat gold medal and diploma at the award ceremonies in December.

In addition to Bialiatski, human rights activists from Ukraine and Russia also shared last year's prize, in what was seen as a strong rebuke to Russian President Vladimir Putin after his invasion of Ukraine.

Other previous winners include Nelson Mandela, Barack Obama, Mikhail Gorbachev, Aung San Suu Kyi and the United Nations.

Unlike the other Nobel prizes that are selected and announced in Stockholm, founder Alfred Nobel decreed that the peace prize be decided and awarded in Oslo by the five-member Norwegian Nobel Committee. The independent panel is appointed by the Norwegian parliament.

The peace prize was the fifth of this year's prizes to be announced. A day earlier, the Nobel committee awarded Norwegian writer Jon Fosse the prize for literature. On Wednesday, the chemistry prize went to U.S.-based scientists who study quantum dots — whose applications include electronics and medical imaging.

The physics prize went Tuesday to three scientists who gave us the first glimpse into the superfast world of spinning electrons. A pair of scientists whose work enabled mRNA vaccines against COVID-19 won the Nobel Prize in medicine on Monday.

Nobels season ends next week with the announcement of the winner of the economics prize, formally known as the Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel.
