Why did Latin become the main literary language in Denmark after Christianity was introduced?

The introduction of Christianity to Denmark during the 10th and 11th centuries brought the region into the sphere of classical and medieval European culture, which established Latin as the predominant literary language.12

The Roman Catholic Church utilized Latin as the primary language for administration, theology, philosophy, and history. By introducing the practice of writing on parchment using the Latin alphabet, the church provided a medium for more sustained literary efforts than the earlier runic alphabet, which had been primarily used for short inscriptions on stone or metal.312

While runic writing continued to be used for epigraphic purposes, Latin became the standard for formal and scholarly works, such as the Gesta Danorum by Saxo Grammaticus. Over time, the use of the Latin alphabet eventually expanded to include the recording of native vernacular writings as well.12
