Azerbaijan's lightning military operation triggered an exodus unparalleled in the South Caucasus since the war in which Armenians took over the territory as the Soviet Union broke up, and hundreds of thousands of Azeris fled.
Azerbaijan says it is prepared to respect ethnic Armenian rights as it reabsorbs the region, but with a history burdened by folk memories of alleged genocide, ethnic cleansing, pogroms and at least two wars, the Armenians are fleeing in fear.
By Thursday morning, Yerevan said 65,036 people had crossed into neighbouring Armenia, most driving for more than 24 hours with their belongings down a choked mountain corridor through Azerbaijan.
"This is one of the darkest pages of Armenian history," said Father David, a 33-year-old Armenian priest who came to the border to provide spiritual support for those fleeing.
"The whole of Armenian history is full of hardships."
Many of the Armenians in heavily laden cars, trucks, buses and even tractors spoke of spending cold mountain nights with hunger and fear churning in their stomachs.
In Soviet times, Nagorno-Karabakh enjoyed autonomy within the Soviet republic of Azerbaijan.
But as the Soviet Union crumbled the First Karabakh War erupted.
About 30,000 people were killed between 1988 and 1994 and more than a million people were displaced, more than half of them Azeris.
In 2020, Azerbaijan struck back, reclaiming swathes of land in and around Karabakh in a 44-day war, setting the stage for last week's conquest.
Billionaire banker and philanthropist Ruben Vardanyan led Karabakh's separatist government from November 2022 until February.
During his short time in office, Azerbaijan had called Vardanyan an obstacle to peace.
He had also fallen out with Armenia's prime minister over the role of Russian peacekeepers.
On Thursday, Azerbaijan said Vardanyan had been taken to the capital Baku and charged with illegally crossing the border after he was arrested trying to escape into Armenia as part of the mass departure.
Vardanyan's wife Veronika Zonabend said she asked for people's "prayers and support for my husband's safe release".
Azerbaijan's victory and the surrender of Karabakh's weapons change the contours of the South Caucasus, where Russia, the United States, Turkey and Iran all vie for influence.
Armenia has blamed its ally Russia, preoccupied with the war in Ukraine, for not doing anything to help.
But Moscow says Armenian Prime Minister Nikol Pashinyan has only himself to blame, and should not have sought closer ties with the West.
The US, home to the world's second-largest Armenian diaspora, has courted Armenia with words and humanitarian aid but criticised Azerbaijan, which has close relations with Turkey.
Samantha Power, head of the US Agency for International Development (USAID), met Azerbaijani President Ilham Aliyev in Baku on Wednesday after visiting Armenia.
Power "stressed the urgency of allowing unhindered humanitarian access to Nagorno-Karabakh, including those stuck in the Lachin Corridor, and the urgent need for expanded access for humanitarian groups", a spokesperson said.
"The Azerbaijani president noted that the civilian population had not been harmed during the anti-terrorist measures, and only illegal Armenian armed formations and military facilities had been targeted," Azerbaijan said.
"Touching upon the rights of Armenian residents living in the Karabakh region, President Ilham Aliyev emphasised that, like other ethnic minorities living in Azerbaijan, their rights would be ensured within the framework of the country's legislation and international obligations."
