Since the 15th century, de Wecks have served in all leading political offices of the country except that of Federal Councillor.
[1] The family was founded in the 14th century by the messenger Pierre du Borjat, called Cugnyet, who became a citizen of Fribourg in 1507 and Germanized his name to Weck.
By the 1520s, the Wecks were numerously represented in the city's governing bodies.
In 1782, the Wecks obtained the right to use the nobiliary particle, de, underlining their position as part of Fribourg's patriciate.
[2] In the 19th and 20th century, de Wecks occupied senior positions in government, the military and other public positions, including six times the office of Councillor of State (member of the cantonal government) of Fribourg.
