| The ethnic problems those are covered by the bipolar structure gradually reveal after the cold war. The statistics show that the war conflicts of The Post-cold War Era are,in the number, more than The Cold War’s, most of them are caused by the ethnic issues. It can be said that appropriately dealing with the ethnic issues are related to not only a country’s stability and prosperty, but a region and throughout the world. The Versailles-Washington Syestem which is established by the Powers opens Pandora’s box of the ethnic iusses of the20th century. Among them, the Polish German minority problem is specially concerned by people. The reason is that the times it appears in the agenda of the National League is more often than the other minorities. Moreover, It also is linked with the evolution of the political landscape in Europe and the outbreak of the World War II.By the study of the origin of the Polish German minority, the policy of the Polish German minority and the reaction of the Germany, the auther try to solve the formulation of Polish de-Germanization policy and implement effection,the Polish German minority problem in the position of the German-Polish relations and the problem influence to the German-Polish relations,the relationship between the Polish German minority problem and the outbreak of the World War II.By the research,I make the conclusion that the Poland is trying to make it a Nation-state as "Poland is polish Poland". In the guide of the ideology, the Poland introduces to a guidelines of the polonisation minority policy. For millions of German minorities in its torritory, The specific policy is de-Germanization. The policy suffers absolutely failed, the most important reason is the contradiction between the goal of Nation-state and the reality of multinational state.It causes many serious consequences. First of all, the policy make the German minority problem one of the major obstacles of normalization of German-Polish relations;Second, Acting with undue haste of the de-Germanization policy causes the fierce resistance of the German minority,moreover, It provides a pretext for Hitler launching the war.I want to emphasize that there is no intention to exonerate Hitler; but, historically, The Poland is also certain responsible for the outbreak of war. In a word, the Polish German minority problem is a domestic issue,It is also a international iusse.Besides,those twice aspects isn’t also isolated from each other. On the one hand, when the Polish German minority problem is treated as a domestic iusse, once the policy of the Polish government improper,German minority attracts international attention for its situation through various means, such as Germany and national League, which lead to a great uproar internationally; simultaneously, it also generates a negative impact on the German-Polish relations. On the other hand, the Polish German minorities are victims of changes in the international situation and he German-Polish relations;any change of them materially affects the situation of the Polish German minority. I believe that only when the Humans learned introspection and tolerance, we could ultimately move towards to a mentally compatible of human community by studying this period’s history. However, blood lessens is indispensable in the process. |
