The country's previous leader has been sentenced to death for crimes against humanity due to her severe measures on student-led protests which led to her ousting.
Hasina was declared culpable of allowing lethal force to be used against demonstrators, with approximately 1,400 individuals were killed during the turmoil in the previous year.
Hasina was tried without her presence by the International Crimes Court in Bangladesh, as she resides in exile in India since she was forced from power in July 2024.
Prosecutors accused her of being the mastermind of numerous deaths during the protests. The former leader rejected every accusation, describing the process as "prejudiced and driven by politics".
The decision signifies a decisive point for Bangladesh, as the protests revealed fury over years of repression. Next of kin of victims and injured had called for strict sentences.
Answering the judgment in a comprehensive declaration, the former leader stated the death penalty was the interim government's way of "eradicating the Awami League" as a governing body and that she was satisfied of her leadership's history on individual freedoms.
"I do not fear to face my accusers in a fair court where the facts can be assessed and reviewed impartially."
The nation's capital, Dhaka, where the legal proceedings occurred, was under enhanced protection ahead of the decision on Monday, with many of Hasina's critics organizing a demonstration and cheering as the sentence was declared.
The city has seen a sudden increase in disturbances, with numerous incendiary devices set off and public transport vehicles burned in the time before the verdict.
A minimum of one detonation was reported in Dhaka on Monday morning, with no casualties reported, local police official Jisanul Haque told press agencies.
The protest movement led by students during 2024 began with demands to abolish public sector reservation policies but evolved into a wider anti-government movement.
International human rights monitors said in a report in February that the approximately 1,400 deaths could represent "crimes against humanity".
The study recorded the gunfire from minimal distance of a number of activists, the intentional injuring of further participants, unwarranted detentions and torture.
Leaked audio of a telephone conversation involving Hasina authenticated by external reviews during the current year indicated she had authorized the use of "deadly arms" in July 2024. The recording was presented in court during the trial.
Before the decision, kin of those who died in the demonstrations told press outlets they wanted the former leader to face strict penalties.
Ramjan Ali, whose brother was shot dead in July 2024, said he wanted "exemplary punishment" for her and co-accused who have "engaged in retaliatory actions and exploited their positions".
Another relative, whose spouse died near Dhaka in August 2024, said she wanted Hasina's sentence to be "implemented before the election".
"Only then the kin of victims [in the protests] will obtain solace in their hearts."
Since Hasina's ousting, an interim government headed by Nobel laureate Muhammad Yunus has assumed control. A national vote is set for February 2026.
However, the Awami League, the former ruling party, was prohibited by Bangladesh's temporary leadership in May.
The former leader cautioned in the previous month that if the the League's representatives were barred from participating in the upcoming election, countless would abstain the vote.
The verdict now poses a international dilemma for the neighboring countries. Authorities have sought her repatriation but to date India has expressed no readiness to acquiesce.
Hasina's state-appointed lawyer her legal counsel said he was "sad [and wishes] the decision had been otherwise".
"I even cannot appeal because my represented individuals are away; which is why I am disappointed," he added.
Recently, Hasina's lawyers said they had lodged a prompt application to the UN highlighting major judicial fairness and due process issues at the ICT.
The former leader faced trial in conjunction with her previous domestic affairs official and police chief.
Even though the verdict grants partial finality to families of killed in the protests, it may have minimal effect on calming the state's ideological splits.
"The anger against Sheikh Hasina and the the former ruling faction has not decreased," a civil liberties campaigner in Dhaka told news organizations. "The leader and her faction has said sorry or demonstrated contrition for the deaths of numerous individuals."
She said "This complicates matters for the faction to gain approval by a most citizens in this country."
The campaigner further stated that the punishment was not resolution for the kin of those killed and injured.
"We work with numerous persons who lost their limbs forever, they are now disabled, as a result of the harsh measures. They are incapable of excusing her."
David Bergman, a commentator on the nation's politics, said the "very nature of the conviction could make it even more difficult" for her party to become a standard element of Bangladeshi politics again.
This could alter if "an expression of regret occurs and a distancing from the former leader and the old leadership," he stated.
