German-American Day is a holiday that celebrates Americans of German heritage, many of whom have been living in this country for hundreds of years. The holiday is celebrated on the date when 13 German families came to the colonies of America in 1683. They created the first German settlement in the colonies, which was in Pennsylvania. They later became the first group of people to petition for the end of slavery. Many parts of the American culture, including some of the most American foods out there: hamburgers and hotdogs, are rooted in German culture. This holiday was proclaimed by Ronald Reagan in 1987.
