This period also saw the rise of the Norwegian romantic nationalism, as Norwegians sought to define and express a distinct national character. The movement covered all branches of culture, including literature (Henrik Wergeland 1808–1845, Bjørnstjerne Bjørnson 1832–1910, Peter Christen Asbjørnsen 1812–1845, Jørgen Moe 1813–1882), painting (Hans Gude 1825–1903, Adolph Tidemand 1814–1876), music (Edvard Grieg 1843–1907), and even language policy, where attempts to define a native written language for Norway led to today's two official written forms for Norwegian: Bokmål and Nynorsk.
