World War I | Timeline of Events In 1914

World War I was a global conflict fought between the Central Powers of Germany, Austria-Hungary, the Ottoman Empire and Bulgaria; and the Allies which was a coalition of many nations, most prominently the Great Britain, France, Russia, Japan and Italy. It began on July 28, 1914 and ended on November 11, 1918. The immediate events leading to World War I were the assassination of Archduke Franz Ferdinand, the presumptive heir of the Austro-Hungarian Empire; and the July Crisis. 1914, the first of four years of WW1, saw many important events. Germany had great success in its initial campaigns but was stopped in its planned invasion of Paris by the Allies; while Austria-Hungary was defeated in its Serbian campaign. Moreover, war began in Africa with the invasion of Togoland by Britain and France; and in Asia with the declaration of war by Japan on Germany. Here is a timeline of events of World War I in 1914.
