How did schools and courts support the use of West Frisian in Friesland?

In the province of Friesland, the use of West Frisian in schools and courts was supported through a gradual process of recognition that gained momentum during the 20th century:

• Schools: In 1937, West Frisian was accepted as an optional course in elementary schools. By 1955, it was officially approved as a language of instruction for the first two years of elementary education, though it remains used in this capacity by only about one-fourth of all schools.1
• Courts: The use of West Frisian in courts of law was formally approved in 1956.1

These developments were part of a broader "Frisian movement" that emerged in the 19th century to preserve the language and culture. Additionally, the Frisian Academy (Fryske Akademy) was founded in 1938 to support these efforts. Despite these advancements, Dutch remains the primary standard language for most formal instruction, media, and administration in the province.12
