German-American Day is a holiday in the United States, observed annually on October 6. The holiday, which celebrates German American heritage, commemorates the date in 1683 when 13 German families from Krefeld near the Rhine landed in Philadelphia. These families subsequently founded Germantown, Pennsylvania, the first German settlement in the original thirteen American colonies. Originally celebrated in the nineteenth century, German-American Day died out in World War I as a result of the anti-German sentiment that prevailed at the time. The holiday was revived in 1983.
In 1983, President Ronald Reagan proclaimed October 6th as German-American Day to celebrate and honor the 300th anniversary of German American immigration and culture to the United States. On August 6, 1987, Congress approved S.J. Resolution 108, designating October 6, 1987, as German-American Day. It became Public Law 100-104 when President Reagan signed it on August 18. A proclamation (#5719) to this effect was issued October 2, 1987, by President Reagan in a formal ceremony in the White House Rose Garden, at which time the President called on Americans to observe the Day with appropriate ceremonies and activities.
