Wikipedia - Mentioned first in 985 as Mons Beliardae, it became a county of the Holy Roman Empire in the 11th century. In 1397 the town, known in archaic German as Mömpelgard, passed by marriage of Henriette, heiress of county to Eberhard IV, Count of Württemberg, to the counts (later dukes) of the House of Württemberg . In 1524, 10 years earlier than in Württemberg, duke Ulrich and reformer William Farel made Mömpelgard Protestant (specifically Lutheran). From 1598 to 1608, the architect Heinrich Schickhardt build several landmarks of the city, like St. Martin, a castle, a bridge, a college and several hotels.

After the French Revolution, it was briefly incorporated into the Rauracian Republic. In 1793 the town was annexed to France, which was confirmed in 1796 and by the Reichsdeputationshauptschluss of 1806, when Württemberg was compensated with other areas, and became a kingdom.
As a consequence of the former rule under the dukes of Württemberg, it has been for centuries one of the few Protestant (specifically Lutheran) enclaves in France.

French protestants were brought to Canada by the British to Nova Scotia as settlers. While you will find references to these settlers from Montbéliard stating they were Huguenots, it is more likely that they were Lutherans.
