paragraph_text: The causes of World War I included many factors, including the conflicts and antagonisms of the four decades leading up to the war. The Triple Entente was the name given to the loose alignment between the United Kingdom, France, and Russia after the signing of the Anglo-Russian Entente in 1907. The alignment of the three powers, supplemented by various agreements with Japan, the United States, and Spain, constituted a powerful counterweight to the Triple Alliance of Germany, Austria-Hungary, and Italy, the third having concluded an additional secret agreement with France effectively nullifying her Alliance commitments. Militarism, alliances, imperialism, and nationalism played major roles in the conflict. The immediate origins of the war lay in the decisions taken by statesmen and generals during the July Crisis of 1914, the spark (or casus belli) for which was the assassination of Archduke Franz Ferdinand of Austria.

paragraph_text: Over time, the relative power of these five nations fluctuated, which by the dawn of the 20th century had served to create an entirely different balance of power. Some, such as the United Kingdom and Prussia (as the founder of the newly formed German state), experienced continued economic growth and political power. Others, such as Russia and Austria-Hungary, stagnated. At the same time, other states were emerging and expanding in power, largely through the process of industrialization. These countries seeking to attain great power status were: Italy after the Risorgimento, Japan after the Meiji Restoration, and the United States after its civil war. By the dawn of the 20th century, the balance of world power had changed substantially since the Congress of Vienna. The Eight-Nation Alliance was a belligerent alliance of eight nations against the Boxer Rebellion in China. It formed in 1900 and consisted of the five Congress powers plus Italy, Japan, and the United States, representing the great powers at the beginning of 20th century.

paragraph_text: Originally the Emperor and non-warrior nobility employed these warrior nobles. In time, they amassed enough manpower, resources and political backing in the form of alliances with one another, to establish the first samurai-dominated government. As the power of these regional clans grew, their chief was typically a distant relative of the Emperor and a lesser member of either the Fujiwara, Minamoto, or Taira clans. Though originally sent to provincial areas for a fixed four-year term as a magistrate, the toryo declined to return to the capital when their terms ended, and their sons inherited their positions and continued to lead the clans in putting down rebellions throughout Japan during the middle- and later-Heian period. Because of their rising military and economic power, the warriors ultimately became a new force in the politics of the court. Their involvement in the Hōgen in the late Heian period consolidated their power, and finally pitted the rival Minamoto and Taira clans against each other in the Heiji Rebellion of 1160.

In August 1937, Generalissimo Chiang Kai-shek deployed his best army to fight about 300,000 Japanese troops in Shanghai, but, after three months of fighting, Shanghai fell. The Japanese continued to push the Chinese forces back, capturing the capital Nanking in December 1937 and committed which was known as Nanking Massacre. In March 1938, Nationalist forces won their first victory at Taierzhuang. but then the city of Xuzhou was taken by Japanese in May. In June 1938, Japan deployed about 350,000 troops to invade Wuhan and captured it in October.
