In 1863, Hale wrote a letter to President Abraham Lincoln. During this time, America was divided by the Civil War. Northern and Southern states were fighting each other. Lincoln agreed with Hale. He thought that a national Thanksgiving could help unite the country.
Thanks to Hale, Lincoln made a proclamation, or a public announcement. He said the last Thursday of every November would be Thanksgiving Day.
Melanie Kirkpatrick wrote a book about Hale.
“Hale’s accomplishment was huge,” she says. “Thanksgiving is an important part of our history and lives today.”
