Sheikh Hasina once helped rescue Bangladesh from military rule, but her time in power has seen the mass arrest of her political opponents and human rights sanctions against her security forces.
Since July, the autocratic premier has faced mass protests that began as university student-led rallies against civil service job quotas, but which have morphed into some of the worst unrest of her 15-year tenure, with opponents demanding she step down.
The protests were largely peaceful until attacks on demonstrators by police and pro-government student groups, sparking international condemnation.
The 76-year-old won a fifth term as prime minister in January, with the opposition boycotting a vote they said was neither free nor fair.
At the time, Hasina branded the main opposition party a "terrorist organisation".
Critics accuse her government of a litany of rights abuses including the murder of opposition activists.
The daughter of a revolutionary who led Bangladesh to independence, Hasina has presided over breakneck economic growth in a country once written off by US statesman Henry Kissinger as an irredeemable "basket case".
Last year she promised to turn all of Bangladesh into a "prosperous and developed country", but around 18 million young Bangladeshis are out of work, according to government figures.
- Economic rise -
Hasina was 27 and travelling abroad when renegade military officers murdered her father, prime minister Sheikh Mujibur Rahman, along with her mother and three brothers in a 1975 coup.
She returned after living in exile for six years to take the reins of her father's Awami League party, beginning a decade-long struggle that saw her subjected to lengthy stretches of house arrest.
Hasina joined forces with Khaleda Zia's Bangladesh Nationalist Party (BNP) to help oust military dictator Hussain Muhammad Ershad in 1990.
But they soon fell out and their ensuing rivalry has since dominated Bangladeshi politics.
Hasina first served a term as prime minister in 1996, but lost to Zia five years later.
The pair were then imprisoned on corruption charges in 2007 after a coup by a military-backed government.
The charges were dropped and they were free to contest an election the following year.
Hasina won in a landslide and has been in power ever since.
The 78-year-old Zia meanwhile is in ailing health and confined to hospital after graft charges saw her sentenced to a 17-year prison term in 2018, with top leaders from her party also behind bars.
Hasina has been praised by supporters for leading Bangladesh through a remarkable economic boom, largely on the back of the mostly female factory workforce powering its garment export industry.
Bangladesh, one of the world's poorest countries when it gained independence from Pakistan in 1971, has grown an average of more than six percent each year since 2009.
Poverty has plummeted and more than 95 percent of the country's 170 million people now have access to electricity, with per capita income overtaking India in 2021.
Hasina also received international acclaim for opening Bangladesh's doors to hundreds of thousands of Rohingya refugees fleeing a 2017 military crackdown in neighbouring Myanmar.
And she has been hailed for a decisive crackdown on Islamist militants in the Muslim-majority nation after five homegrown extremists stormed a Dhaka cafe popular with Western expatriates and killed 22 people in 2016.
- Silencing dissent -
But her government's intolerance towards dissent has given rise to resentment at home and expressions of concern from Washington and elsewhere.
Five top Islamist leaders and a senior opposition figure were executed over the past decade after convictions for crimes against humanity committed during the country's brutal 1971 liberation war.
Instead of healing the wounds of that conflict, the trials triggered mass protests and deadly clashes.
Her opponents branded them a farce, saying they were a politically motivated exercise to silence dissent.
The United States imposed sanctions in 2021 on an elite branch of Bangladesh's security forces and seven of its top officers over charges of widespread human rights abuses.
In the face of mounting protests, Hasina has insisted she has worked for her nation.
Last month she toured areas of Dhaka damaged during days of deadly unrest, including a metro station that was among several government buildings torched or vandalised.
"Over 15 years, I've built this country," she told reporters, condemning the damage to infrastructure. "What didn't I do for the people?
