Until the 19th century in the area of three valleys, Meža, Mislinja and Drava, only few received formal education in parish, burgher and trivial schools. Knowledge about the Earth, weather, diseases in animals and humans, their treatment and healing herbs was passed on to younger generations by oral tradition. In Koroška region the first records of this knowledge arose in the 18th century. The oldest preserved written document about the use of Slovenian language in the Meža Valley is the Črna manuscript (“Črnjanski rokopis”) from the 17th century. A century younger Leše manuscript (“Leški rokopis”) is an example of ‘Bukovništvo’ in Koroška region. Literacy and printing strengthened the economic development and scientific research. The in 1851 established Slovenian publishing house Mohor’s Society (Mohorjeva družba) in Klagenfurt had an important educational role in Koroška region. The Reading badge (Bralna značka) developed into an all Slovenian movement of reading culture. It was first presented in Prevalje in 1961. The use of Slovenian language in primary schools in the 19th century was not self-evident. Under the influence of Germanisation the utraquist schools predominated, with the dominant German language. Additionally this was aided by the German Society Schulverein. After World War I German language was replaced with Serbian. Economic and political changes affected the organization of schools. Due to the geographical terrain numerous branch schools with a specific learning process are characteristic of the area. The introduction of compulsory education is closely linked to the development of industry, which needed more and more educated workers for creating more capital. Individuals gained expert knowledge at foreign colleges and universities, but most of them were trained workers. The gap was filled in after 1920, with the introduction of burgher schools, and in the period of socialism with vocational and grammar schools. Companies organized private education and supported the program of Aduld education institutes and faculties in Maribor and Ljubljana. An important part of education are scholarships, initially to support individuals, but in the period of state-socialism to support almost every student, which resulted in a general increase of education. Staying in a dormitory enabled also the education of the most faraway students. From the second half of the 19th century informal education took place in various and numerous associations, which have hosted a number of lectures. Teachers, doctors and other intellectuals involved themselves in the process of adult education, with lectures and exhibitions.
