The title of this study is: The Swedish assimilation of Scania during the period 1658-1720 - In descriptions of Danish and Swedish popular historians` during 20th century to current view. View of history, nationalism and science .                                                                                                                                              The study concerns the Swedish, after the conquest of Scania 1658, attempts to induce feelings of Swedish nationality to the people in former Danish province of Scania 1658-1720. The goal of this study was to analyze 20th century and present Swedish and Danish historians’ descriptions of the Swedish and Danish treatment of the native Scania population. The aim was further to describe this historians` view of native rebellious group called “snapphanar” and which measures were taken to assimilate the Scanian population to Swedish realm. Lastly, the historians view above concerning a presence of a native Scanian regional or national identity was studied.                I studied writings of three popular historians from Denmark and from Sweden respectively. To compensate for the influence of nationalism on historiography, sources from three periods during the 20th and the current century was used.                                            In the attempt to reach these main goals I have analyzed the authors’ books and the Swedish and Danish versions of the website Wikipedia. All the popular historians´ mean that the people of Scania felt national identity, except Åberg which mean that they also had a regional identity. The Swedish scholarship had a big influence of making the native population citizens of the Swedish crown. Also the punishment had a big impact, which mainly affected the partisan group called snapphanar. This is in detail described by Wikipedia. 20th century Danish popular historians` describe the abuses on the natives by the Swedish realm while the Swedish historians mostly describe snapphanars rubies on them.
