德國是否最主要引起第一次世界大戰？

Causes of World War I :

World War I was immediately precipitated by the assassination of Archduke Francis Ferdinand of Austria-Hungary by a Serbian nationalist in 1914. There were, however, many factors that had led toward war. Prominent causes were the imperialistic, territorial, and economic rivalries that had been intensifying from the late 19th cent., particularly among Germany, France, Great Britain, Russia, and Austria-Hungary.

Of equal importance was the rampant spirit of nationalism, especially unsettling in the empire of Austria-Hungary and perhaps also in France. Nationalism had brought the unification of Germany by “blood and iron,” and France, deprived of Alsace and Lorraine by the Franco-Prussian War of 1870–71, had been left with its own nationalistic cult seeking revenge against Germany. While French nationalists were hostile to Germany, which sought to maintain its gains by militarism and alliances, nationalism was creating violent tensions in the Austro-Hungarian Monarchy; there the large Slavic national groups had grown increasingly restive, and Serbia as well as Russia fanned Slavic hopes for freedom and Pan-Slavism.

Imperialist rivalry had grown more intense with the “new imperialism” of the late 19th and early 20th cent. The great powers had come into conflict over spheres of influence in China and over territories in Africa, and the Eastern Question, created by the decline of the Ottoman Empire, had produced several disturbing controversies. Particularly unsettling was the policy of Germany. It embarked late but aggressively on colonial expansion under Emperor William II, came into conflict with France over Morocco, and seemed to threaten Great Britain by its rapid naval expansion.

These issues, imperialist and nationalist, resulted in a hardening of alliance systems in the Triple Alliance and Triple Entente and in a general armaments race. Nonetheless, a false optimism regarding peace prevailed almost until the onset of the war, an optimism stimulated by the long period during which major wars had been avoided, by the close dynastic ties and cultural intercourse in Europe, and by the advance of industrialization and economic prosperity. Many Europeans counted on the deterrent of war's destructiveness to preserve the peace.

(1)德國要背起部分的戰爭責任(2)有,法國刀要背起部分的戰爭責任

德、法左第一次世界大戰前已是世仇。普法戰爭(1870-1871年)19世紀中期，意大利、普魯士(德國)均致力建立民國，但受到法國等阻撓。1870年，普魯士(德國)挑起普法戰爭，意大利首先乘機完成了統一，而普魯士(德國)亦左1871年統一了德國。法國左這次戰爭中大敗，被迫簽署《法蘭克福條約》，支付大量賠款，並割讓阿爾薩斯和洺林。從此，德、法兩國的糾紛便無止了。普法戰爭結朿後，法國人飽受恥辱，對德國產生極強的報復心理。
1914年，列強間長久以來所積累的恩怨，終藉一宗暗殺事件而爆發第一次世界大戰。
那一宗暗殺事件是歷史上有名的「塞拉耶佛暗殺事件」

是，不错。德國是最主要引起第一次世界大戰
