First world war kab aur kaise hua

 The First World War, also known as the Great War, was a global war that lasted from 1914 to 1918. It involved the majority of the world's nations, including all of the great powers, and was primarily centered in Europe. The war began with the assassination of Archduke Franz Ferdinand of Austria-Hungary by a Serbian nationalist on June 28, 1914. This event sparked a chain reaction of alliances and mobilizations that ultimately led to the outbreak of war.

The conflict was characterized by trench warfare and widespread use of new technologies, such as machine guns, tanks, and chemical weapons. The war ended on November 11, 1918, with the signing of the Armistice of Compiègne, which marked the defeat of the Central Powers and the end of the war. The First World War was one of the deadliest conflicts in human history, with an estimated 10 million military deaths and another 7 million civilian deaths.
