World War I began in 1914, after the assassination of Archduke Franz Ferdinand, and lasted until 1918. During the conflict, Germany, Austria-Hungary, Bulgaria and the Ottoman Empire (the Central Powers) fought against Great Britain, France, Russia, Italy, Romania, Japan and the United States (the Allied Powers).
The immediate cause of World War I that made the aforementioned items come into play (alliances, imperialism, militarism, nationalism) was the assassination of Archduke Franz Ferdinand of Austria-Hungary. In June 1914, a Serbian-nationalist terrorist group called the Black Hand sent groups to assassinate the Archduke.
There was no single event that caused World War One (WW1). War happened because of several different events that took place in the years building up to 1914. Firstly, there was the role of empire. Great Britain, Germany, Austria-Hungary and Russia all had empires.Jun 29, 2016
The first country to declare war in WWI was Austria-Hungary. That country issued an ultimatum to Serbia after the assassination of the Austro-Hungarian Archduke Franz Ferdinand. When Serbia rejected the ultimatum, Austria-Hungary declared war on July 28. Austria-Hungary was an ally of Germany.
The simplest answer is that the immediate cause was the assassination of Franz Ferdinand, the archduke of Austria-Hungary. His death at the hands of Gavrilo Princip – a Serbian nationalist with ties to the secretive military group known as the Black Hand – propelled the major European military powers towards war.
The aircraft played a pivotal role for all sides of World War 1 when the conflict began in 1914. Early forms were typically unarmed and used in the reconnaissance role until personal weapons were added. From there, the machine gun was finally fixed to these aircraft to create the 'fighter' aeroplane.
Soldiers also made dugouts and funk holes in the side of the trenches to give them some protection from the weather and enemy fire. The front-line trenches were also protected by barbed-wire entanglements and machine-gun posts. Short trenches called saps were dug from the front-trench into No-Man's Land.
Trench warfare is a form of land warfare using occupied fighting lines consisting largely of trenches, in which troops are significantly protected from the enemy's small arms fire and are substantially sheltered from artillery. The most prominent case of trench warfare is the Western Front in World War I.
