According to Jelle Krol, the strictness with which the
Third French Republic imposed its French-only policy throughout the educational system as well as its rejection of all requests for classes in minority languages must be seen in the light of France's humiliating defeat in the
Franco-Prussian War and the resulting
Germanophobia and
Revanchism over the loss of
Alsace and
Lorraine. The Government of the Republic was accordingly unwilling to tolerate the
German language and other minority languages in French schools or society. The first Diwan school was created by a few parents in 1977 at
Lampaul-Ploudalmézeau (Breton: Lambaol-Gwitalmeze) near
Brest, because the centralised French state schools were unwilling to offer the Breton language in the curriculum. The initial nursery school was followed by the first primary school in 1980, the first
collège in 1988 and the first
lycée in 1994. In 2008, Diwan schools celebrated their 30th anniversary and organised
Ar Redadeg, a non-stop foot race through Brittany in support of Breton-language learning in schools, which has little support from the French central government. In 2019–2020 4,307 pupils attended Diwan schools throughout Brittany at all levels from preschool to the
Baccalauréat. The network included 48 primary-level schools and 8 secondary schools (six and two ). ==Schools formed==
