Duckburg is a city in a few of the Disney games. It appears mostly in the vintage games with Donald Duck including Disney's PK: Out of the Shadows, Disney's Donald Duck: Going Quackers and Donald Duck's Playground. However, it also appears in DuckTales and its remastering, DuckTales: Remastered.
Duckburg has been given a long history by many creators, including such writers as Barks and current Duck comic writer Don Rosa.
In the comics, the location that would eventually become known as Duckburg was originally known as "Fort Drake Borough," a fort built in the 16th century by British explorer Sir Francis Drake. By the 19th century, the fort had been handed over by its departing British occupants to Cornelius Coot, who renamed the fort "Duckburg." "Drake" means a male duck, while "borough" and "burg" are synonyms.
Duckburg remained a quiet, small town until the arrival of wealthy businessman Scrooge McDuck. McDuck had bought the old fort from Clinton Coot, a descendant of Cornelius. Scrooge proceeded to construct his famous money bin and established various businesses in and around Duckburg. This construction caused Duckburg's population to swell, and turned the small town into a bustling city within several decades' time.
Duckburg is probably the largest city in the state of Calisota, but not the capital city. There are no references to the governor, legislature, Capitol, etc., of Calisota in any of the many stories about Duckburg. Duckburg seems to have its own governor, however, if it is not a sort of city state. On more than one story a "Duckburg embassy" is shown, which would place it outside the USA at a legislative level. In a story by Barks the Duckburg embassy displays a flag of Duckburg, which consists of a white duck over a green field.
Duckburg maintains a traditional rivalry with Goosetown, another city of Calisota.
