Denmark
A large majority (86%) of Danes speak English as a second language, generally with a high level of proficiency. German is the second-most spoken foreign language, with 47% reporting a conversational level of proficiency. Denmark had 25,900 native speakers of German in 2007 (mostly in the South Jutland area).
Norwegian language conflict
In the United Kingdoms of Denmark and Norway (1536–1814), the official language was Danish. The urban Norwegian upper class spoke ""dansk-norsk"", Dano-Norwegian, a form of Danish with Norwegian pronunciation and other minor local differences while the majority of the population spoke their local and regional dialects. After the two countries separated in 1814, Dano-Norwegian remained the sole official language until 1885.
