2. THE FIRST World War
Was fought between 1914 and 1918, by various European countries and their colonies, the USA, Japan, China and some Latin American republics.
2.1. The causes of the war:
The Austro-Hungarian Empire and the Russian Empire competed for control of the Balkans. At the same time, Serbia was angry about the expansion of the Austro-Hungarian Empire into the area.
France wanted to recover the region of Alsace-Lorraine, which it had lost to the German Empire after the Franco-Prussian War. France and Germany also competed for control of Morocco.
Great Britain saw the supremacy of each merchant navy threatened when the German Empire, become an economic power
These disputes created a pre-war atmosphere, and the European powers continued to increase spending on arms. Governments, through the press, influenced public opinion in favour of war, while pacifist movements, such as the Second International and the Catholic Church, failed in their attempts to avoid war. On 28 June, 1914, Archduke Franz Ferdinand, the heir to the Austro-Hungarian Empire, was assassinated in Sarajevo. The Austrian government blamed Serbia for the assassination and sent them an ultimatum, which was ignored. On 28 July 1914, the Austro-Hungarian Empire declared war on Serbia.
