Legacy

Gustavus Adolphus is widely commemorated by Protestants in Europe as the main defender of their cause during the Thirty Years' War, with multiple churches, foundations and other undertakings named after him. He became a symbol of Swedish pride, and his name is attached to city squares in major Swedish cities like Stockholm, Gothenburg and Helsingborg. Gustavus Adolphus Day is celebrated in Sweden and Finland each year on 6 November, the day the king died at Lützen. One of the traditions on this day is the Gustavus Adolphus pastry. In Finland, the day is also celebrated as "Swedish heritage day". Gustavus Adolphus College, a Lutheran college in St. Peter, Minnesota, is also named for him.

The Gustav-Adolf-Werk (GAW) of the Evangelical Church in Germany, founded on the bicentennial celebration of the Battle of Lützen, has as its object the aid of other churches and commemorates Gustavus' legacy. It is responsible for taking care of the Diaspora work of the EKD and has separate branches internationally. The organization in Austria is called the Gustav-Adolf-Verein. The project of forming such a society was first broached in connection with the bicentennial celebration of the Battle of Lützen on 6 November 1832.

A proposal to collect funds for a monument to Gustavus Adolphus was agreed to, and it was suggested by Superintendent Grossmann that the best memorial to Gustavus Adolphus would be the formation of a union for propagating his ideas. It quickly gained popularity in Germany. The lack of political correctness received some criticism; however, the organization used GAW as its brand in the meanwhile. The Swedish royal family visited the GAW headquarters in Leipzig on the 400th birthday of Gustavus Adolphus, in 1994.
