The name "Württemberg" goes back to the former – until 1918 ruling – dynasty of the Dukes of Württemberg. Their name has its roots in the Castle Wirtemberg (located in Stuttgart-Rotenberg). With the elevation of the Duchy to an Electorate in 1803, the name of the country was officially changed from "Wirtemberg" to "Württemberg". The name "Baden" points out to the town of Baden (Baden-Baden), namesake of the Marquisate of Baden, which appeared in the middle of the 12th century. The word "Baden" ("bath") refers to the existing hot springs there, which were already known by the Romans as a bathing place, which they called "Aquae Aureliae" (Bath of Aurelius).
