From 19 19 to 1920, the Allies signed a series of peace treaties with Germany's allies Austria, Hungary, Turkey and Bulgaria. Together with the Treaty of Versailles, these peace treaties established the Versailles system and established a new ruling order in Europe, West Asia and Africa, which marked the fierce diplomatic struggle between major powers after the end of the First World War.
That is to say, this system was formed in the 19 10 and1920s, which is inconsistent with the period required by this student's thesis.
The following is BCD, which I think is the reason to meet the requirements of this student's thesis.
D is correct, as follows: After World War II, the trend of European unification reached its climax. 1946 In September, British Prime Minister Churchill proposed the establishment of a "United States of Europe". 1950 on may 9th, French foreign minister robert schumann put forward the European coal and steel * * * plan (Schumann plan), aiming at binding Germany. 1951April 18, France, Italy, the Federal Republic of Germany, the Netherlands, Belgium and Luxembourg signed the "Treaty of Paris" for 50 years. On June 1955 and 1, the foreign ministers of six countries participating in the isomorphism of coal and steel in Europe held a meeting in Messina, Italy, suggesting that the isomorphism principle of coal and steel should be extended to other economic fields and a common market should be established. 1957 On March 25th, the foreign ministers of the six countries signed two treaties in Rome, namely the Treaty of Rome, which established the European economic isomorphism and the European atomic energy isomorphism and took effect on June 25th, 1958 and 1.
B is right.
The reasons are as follows: The bipolar pattern existed in the early 1950s-it ended with the unification of Germany in 1990. It is manifested in the military confrontation between NATO and Warsaw Pact led by the United States and the Soviet Union, the struggle for the third world, the mutual economic embargo and blockade, the crazy competition in armaments, the attempt to gain the advantage of defeating the opponents, and the ideological attack on each other.
C is correct.
The reasons are as follows: the evolution of international political structure from bipolar to multipolar is a basic trend of post-war world historical movement, which began in the late 1950 s and showed three parallel historical processes: the capitalist camp evolved from the monopoly of the United States to the tripartite confrontation of the United States, Europe and Japan; The Eastern Group moved from ideological debate to division; "Third World" countries play the role of balancing the two poles in the international political arena in the form of non-aligned movement. The resultant force of these factors has promoted the development of multipolarization. The world is moving towards multipolarization, which is a gradual process. After the trend of multipolarization appeared, the bipolar pattern did not collapse immediately. However, due to the division of the two camps, the content and form of bipolar confrontation have also changed, and the relationship between the United States and the Soviet Union, as the main axis of the Cold War between East and West, has become more prominent.
