During the 19th century spoken Dano-Norwegian language gradually came to incorporate more of Norwegian vocabulary and grammar. At the start of the 20th century, written Dano-Norwegian was mostly identical with written Danish, with only minor differences, such as some additional Norwegian vocabulary in Dano-Norwegian. In 1907 and 1917, spelling and grammar reforms brought the written language closer to the spoken koiné (Dano-Norwegian). Based on the Danish model, the Dano-Norwegian language in Norway was referred to as Rigsmål, later spelled Riksmål, from the late 19th century, and this name was officially adopted in the early 20th century. In 1929, the name Riksmål was officially changed to Bokmål after a proposition to use the name "dansk-norsk" lost with a single vote in the Lagting (a chamber in the Norwegian parliament).
