was detained by Iran's "Morality Police"

for improperly wearing her hijab.

She was loaded into a van where she was reportedly beaten

and then transferred to a detention center

where she collapsed and fell into a coma.

Three days later, she died at the hospital

and protests broke out.

As a result, Iran shut down the country's Internet.

But hundreds of social media posts

of people protesting her death have surfaced

over the last three months,

including videos of women defiantly cutting their hair,

the symbol of beauty the regime wants hidden under the hijab.

The so-called Morality Police patrol

the streets to enforce the regime's strict dress code.

They mostly target women and how they wear the hijab,

and will either fine them or

arrest them and take them to detention centers.

They are one part of the repressive state apparatus

that wields power over Iranians, but far from the only one.

In videos of the protests, we can see different armed groups

violently suppressing the protests.

Understanding who they might be tells us a lot

about the power structure Iranians are fighting to change.

In the 1970s,

Iran was a secular monarchy

that operated as a dictatorship. Under the Shah,

Iranians lacked political freedoms but enjoyed social ones.

They also experienced

economic growth that rapidly transformed Iran

from a traditional conservative

society to an industrial, modernized one.

Soon, economic frustrations and political repression

sparked uprisings calling for new Islamic rule.

They went on for a year, but the regime remained in place

until a crucial turning point: The Army declared neutrality.

It was then that the monarchy collapsed and gave way

to the Islamic Republic that rules today.

But that neutrality that allowed the regime to come to power

was also one of its biggest weaknesses.

The revolutionaries did not trust the army,

which was supposed to be loyal to the Shah,

but stabbed him in the back.

The best strategy was to hedge their bets

by creating a branch of the armed forces

that they could trust much more than the army.

Under the Supreme Leader's rule, the regime kept the old army

but created a separate military group called

the Islamic Revolutionary Guard Corps.

This group was crucial in the long war

Iran fought against Iraq.

The Revolutionary Guard played an important role

in trying to push back the Iraqi army,

and after that, they managed to turn that political capital

into economic influence and political power.

As their importance grew, so did their domestic security role,

which sometimes meant fighting against the people.

Videos verified by Human Rights Watch

show armed forces beating protesters

using assault weapons and men dressed in black

riding motorcycles and firing guns into crowds.

These men, dressed in black, fit the description of the Basij,

a paramilitary volunteer militia under the IRGC

that's fiercely loyal to the supreme leader.

Primarily, it was a force that was created

in order to do social control.

In September, Amnesty International obtained documents

showing the armed forces instructed their chain of command

to "severely confront" protesters,

and a local commander

ordering security forces to "confront mercilessly"

while going as far as causing deaths.

As a result, human rights groups say at least

18,000 protesters have been arrested

and at least 250 have been killed,

including more than 60 children.

And now Iran has started carrying out executions.

The reason so many

protesters are out on the streets

is that Iran's power structure

doesn't give them any alternatives.

Just like the armed forces are a pillar

of the Islamic Republic,

there are several others

supporting the country's power structure.

These are just a few of them.

And while some should be independent, they aren't.

This includes Iran's legislative branch,

because while these government bodies are technically elected,

they are controlled by the regime's

appointed Guardian Council.

That means the regime can disqualify

candidates and reject laws that go through parliament,

overriding the will of the people.

The unelected institutions

have continuously stymied and sabotaged those reforms,

and that has created

a sense of despondency within the society.

So in the last 20 years,

Iranians have taken to the streets at an increasing rate:

against electoral fraud, government corruption,

economic hardship, and again today.

Soon after Amini's death, a video of her funeral went viral.

Women took off their hijabs and the crowd started chanting.

And the chants have taken hold

all over the country.

Usually the pattern of the protests in the past

10, 15 years in Iran is that they often start

with much more narrower objectives or demands.

But this time around, almost from the get-go, the zero-to-100

happened overnight

and immediately there were calls for regime change.

But the system they are trying to change was built

to suppress dissent and protect power at the top.

The idea of having multiple power centers and parallel

institutions, it's for the regime to hedge its bets.

None of these individual elements can on their own pose

a threat to the pinnacle of power in Iran.

Making it nearly impossible

to topple such a multilayered, decentralized power structure.

The fact that there is now no longer

any hopes in the possibility

of reforming the system from within,

it has created a situation in which

the younger generation of Iranians

increasingly believe that they have nothing to lose.

Most of the protesters are young Iranians who were born

after the revolution and inherited a system

they didn't ask for.

Despite the censorship,

young Iranians have caught the world's attention.

Schoolgirls are filming themselves

replacing portraits of the supreme leader with the words

"Woman, life, freedom," setting their hijabs on fire,

and chasing pro-regime educators out of their schools.

The current situation is the product of the Islamic Republic's

failures over the years.

The Islamic Republic failed to create a country

in which the youth could see a future for themselves.

It's really as simple as that.
