Alsace bossue
The Alsace bossue (German : Krummes Elsass, Alsatian and Frankish : "S'Krumme Elsass"), is a territory of Bas-Rhin in Alsace, which includes the three cantons of Sarre-Union, Drulingen and La Petite-Pierre.
Linguistically, the Alsace bossue is predominantly located into the Rhine Franconian area.
The actual borders of this territory are due to the fact that the County of Saarwerden was annexed by France in 1793. In the same year, the department of Moselle gave to Bas-Rhin the communes of Bouquenom and Vieux Sarverden (actually Sarrewerden), these two localities were a French enclave since 1766.
Basically the County of Saarwerden had to be fragmented and distributed to the departments of Moselle, Meurthe and Bas-Rhin, but this project was finally not done. Next, the county was temporarily absorbed by the nearby districts of Moselle and Meurthe until a final decision was made. At the end of the year 1793, the full territory was given to Bas-Rhin.
Another county of Alsace bossue was the County of Lützelstein (comté de la Petite-Pierre).
