Six months ago this week, Mahsa Amini was arrested for allegedly flouting Iran's strict dress code for women. Within days she was dead, sparking the country's biggest protests in years.
The 22-year ethnic Kurd became a household name inside Iran, a rallying point for demands for change. Around the world, she became a hero for women's rights campaigners and a symbol for Western opponents of the Tehran regime.
Amini was visiting the capital Tehran with her brother and cousins when she was arrested as they were leaving a metro station in the city center last September.
Accused of wearing "inappropriate" attire, she was taken to a police station by officers of the morality police.
There she collapsed after a quarrel with a policewoman, according to a short surveillance video released by the authorities.
She spent three days in hospital in a coma before her death on September 16, which the authorities blamed on underlying health issues.
For many, the young woman from the western city of Saqez personified the fight against the obligation to wear the headscarf. Her name became the rallying point for a protest movement that gripped the country for months.
The epitaph engraved on her tomb reads: "You are not dead Mahsa, your name has become a symbol".
Almost overnight, her portrait became ubiquitous in Iran's cities, fly-postered on walls and held aloft by protesters. It even made the cover of some magazines published inside Iran, including the March edition of the monthly Andisheh Pouya.
"Unknown before her death, Mahsa has become a symbol of oppression and her innocent face reinforces this image," said political scientist Ahmad Zeidabadi.
Call for openness
The protests over her death in custody, which began in the capital and in her native Kurdistan province, swiftly mushroomed into a nationwide movement for change.
Public anger over her death merged with "a series of problems, including the economic crisis, attitudes toward the morality police, or political issues such as the disqualification of candidates for election" by Iran's conservative-dominated vetting body the Guardian Council, said sociologist Abbas Abdi.
Spearheaded by young people demanding gender equality and greater openness without a leader or political program, the street protests peaked late last year.
Hundreds of people were killed, including dozens of security force personnel. Thousands more were arrested for participating in what officials described as "riots" and blamed on hostile forces linked to the United States, Israel and their allies.
In February, after the protests abated and supreme leader Ali Khamenei decreed a partial amnesty, the authorities began to release thousands of people arrested in connection with the protests.
Some 22,600 people "linked to the riots" have so far been released, the head of the judiciary, Gholamhossein Mohseni Ejei said this week.
But Abdi said protesters could return to the streets again as the underlying grievances remained unaddressed.
"The demonstrations are over, but I doubt the protest has ended," he said, noting that "the main causes of the crisis remain.
"In the current situation, any incident can trigger new protests."
He cited as an example the public anger sparked by a spate of mystery poisonings that have affected thousands of pupils at more than 200 girls' schools over the past three months.
Quiet change
The mass demonstrations inside Iran, among the largest since the 1979 revolution, prompted some in the exiled opposition to talk of an imminent change of regime.
"Some people, especially in the diaspora, have mistakenly bet on the fall of the Islamic republic in the very near future," political scientist Zeidabadi said.
Zeidabadi argued that the emigres had misunderstood the nature of the protest movement which he said was more "civic" than political.
He stressed that, viewed in that fashion, the movement had produced "results", notably a quiet relaxation in enforcement of the dress code for women.
"A certain degree of freedom from the hijab is tolerated even if the law and the rules have not changed," Zeidabadi said.
He predicted similarly discreet and cautious reforms in other areas, notably the economy, which has been blighted by inflation of around 50 percent and a record depreciation of the rial against the dollar.
"It seems that Tehran has realized the need for a change of policy, although there is no consensus within it on a lasting response to meet the challenge."
