Emma Morano, who made her home in the northern Italian town of Verbania, was the oldest of eight children and one of the oldest people in recorded history; interviews conducted earlier in her life pinpointed Morano's birthdate as November 29, 1899.
She lived through two World Wars, worked in a jute factory and courageously made a decision to separate from an abusive husband at a time when divorce was frowned on.
Ms Morano has said that her longevity was partly down to genetics: her mother reached 91 and several sisters reached their centenary.
She also adhered to a unique diet of two raw eggs and one cooked egg per day and had good genes: The eldest of eight children, Morano had a sister live to 102 and another to almost 100. Jamaican Prime Minister Andrew Holness tweeted his congratulations to her.
"I didn't want to be dominated by anyone", Morano told the New York Times when she was 115. "And cookies. But I do not eat much, because I have no teeth", she told AFP.
"How does my hair look", she asked before blowing out the candles on her 117th birthday cake previous year.

She noted that the government's summons to Twitter had boilerplate language but lacked a specific reason for wanting to know the identities.
Bava has previously told the AP that Morano lost a son to crib death when he was six months old. "When I first met her she ate three eggs a day, two raw in the morning and then an omelette at noon, and chicken at dinner".
Ms Morano ferociously clung to her independence and only took on a full-time caregiver in 2015.
Morano began working in a factory making jute bags when she was 16.
Beside work, she enjoyed herself.
She also defied health advice, Dr Bava said on Saturday.
"When I first knew her she used to eat three eggs a day".
