Why is the Halloween pumpkin called Jack? Is there any origin?

The Halloween pumpkin is called Jack because of an Irish legend. There is a man named Jack in Ireland who was invited by the devil to drink. After drinking, he found that he had no money to pay the bill. Jack persuaded the devil and asked the devil to pay the bill in the form of sixpence.

The drink money, but Jack did not use it to pay, but instead used a silver note to suppress the devil so that the devil could not come out.

Then the devil promised Jack not to scare him for a year, so Jack released the devil.

However, on Halloween the next year, the devil appeared again, but the devil promised not to harass Jack for a year. However, before the year was completely over, Jack died due to an accident.

After Jack's death, Heaven did not accept Jack because Jack was very stingy and inhumane, but Hell did not want to keep him either because he had teased the devil.

Later, Jack had nowhere to go, and finally had to wander around the world without stopping. Carrying a white radish with charcoal in it that the devil gave him to light up the road, Jack found a place to rest.

Later, people in Ireland used potatoes or kohlrabi to make lanterns. In the 1840s, as new immigrants came to the American continent, the new immigrants discovered that there was a material that was more useful than white radish, and that was pumpkin, so what we see today

Jack-o-lanterns are usually made of pumpkins.
