In the medieval period, Danish emerged as a separate language from Swedish. The main written language was Latin, and the few Danish-language texts preserved from this period are written in the Latin alphabet, although the runic alphabet seems to have lingered in popular usage in some areas. The main text types written in this period are laws, which were formulated in the vernacular language to be accessible also to those who were not Latinate. The Jutlandic Law and Scanian Law were written in vernacular Danish in the early 13th century. Beginning in 1350, Danish began to be used as a language of administration, and new types of literature began to be written in the language, such as royal letters and testaments. The orthography in this period was not standardized nor was the spoken language, and the regional laws demonstrate the dialectal differences between the regions in which they were written.
