The state of Maine had soldiers who fought in World War I, and the Maine Army National Guard was the first guard unit deployed.
David Greenham, associate director of the Holocaust and Human Rights Center said, "Part of the original plan was to have a culminating event and most of our focus is on education work."
Greenham said having a day-long seminar specifically for teachers to help them have more tools to use in the classroom is what made this project worthwhile.
"But along the way, we hear so many other additional stories and again meet so many different folks and so that's part of the fun," Greenham said.
Donald Soctomah a Passamaquoddy historic preservation officer said Passamaquoddy soldiers played an important role in World War I. Friday, he shared that knowledge with others.
"I'm always interested in sharing history so people get a wider view of the story," said Soctomah.
Students who are just fans of history said they enjoy learning Maine's involvement in World War I.
High school student Emily Fraser said, "I just like learning about the past it just fascinates me. It's really important to especially for younger people history can dictate the future and make sure that we don't make the mistakes that happened in the past."
Letters ranging from humorous to tragic were donated by family members who had relatives in World War I.
