英语翻译这里的改革我认为是19世纪中叶的“斯堪的纳维亚政治运动”） 背景：当时的瑞－挪国王提倡把丹麦、瑞典和挪威统一成一

Here I think it is the reform of the mid-19th century "the Scandinavian political movement")
Background: At that time, the Swiss - Norwegian King advocate of Denmark, Sweden and Norway into a unified kingdom. This proposal is the cause of the early 19th century, the Napoleonic Wars are caused by the turbulence caused by the impact of the split: Sweden, the eastern region in 1809 into the Grand Duchy of Russia and Finland, and from 1387 a joint Norway and Denmark in 1814 is independent, even though it quickly was forced to become a personal union with Sweden.
Process: Scandinavia, the main political movement started in the first period Shenleishiweixi war [1848] -1850, then Switzerland - the Kingdom of Norway invested considerable military power, and even the end of the second Leishiweixi war [1864], because Sweden's parliament refused to provide more military power.
Finland became part of the Russian empire means it can not with the Nordic countries in the political alliance. Therefore, the "Scandinavian" Geographically, including Denmark, Sweden, Norway, Finland and part of the political "Scandinavian" also including Denmark. Politically, Sweden and Norway to be in the form of personal union with a royal rule. Denmark subsidiary to include Iceland, and the Atlantic Ocean, the Iceland, the Faroe Islands and Greenland [Although history, the Greenland are Norway, according to the Treaty of Kiel, it has been from Denmark governance].
When Sweden - Norwegian military refused to support the Kingdom of Denmark to the annexation of [ethnic] Denmark Shenleishiweixi, the State of the Scandinavian unified political movement will be ended. Shenleishiweixi States and the German public and the Principality of Holstein and Denmark belong to the same personal union. Then, mid-1864, Denmark and Austria support by the Prussian between the second Shenleishiweixi war. During the war is short but significant losses. Shenleishiweixi - Holstein was conquered Prussia. When Prussian win-Prussian War, it established the German Empire, rewrite the balance of forces in the Baltic Sea.
Impact: Scandinavia achieve unification failed. Europe therefore less of a balanced and the big powers Britain, France and Germany. Although Scandinavia always achieve a unified, as early as 1873 the Scandinavian Monetary Union was formally established crowns become common currency until the First World War.
