 The nynorsk movement gained new momentum, putting rural districts and the dialects more in the center of Norwegian politics.In 1973, Norsk språkråd instructed teachers to no longer correct students who used conservative riksmål in their writing, provided these forms were used consistently.The 1973 recommendation by the council was formally approved by parliament in 1981 in what was known as the "liberalization resolution" ("liberaliseringsvedtaket").
