Who Declared War on Serbia in July 1914?
The outbreak of World War I in July 1914 was a complex and multifaceted event, involving the declarations of war by multiple countries. In this article, we will explore who declared war on Serbia in July 1914, and the events that led to the outbreak of the war.
The Assassination of Archduke Franz Ferdinand
The spark that ignited the war was the assassination of Archduke Franz Ferdinand, the heir to the Austro-Hungarian throne, on June 28, 1914, in Sarajevo, Bosnia. The assassination was carried out by Gavrilo Princip, a Serbian nationalist and member of the Black Hand secret society. The Archduke and his wife, Sophie, were visiting Sarajevo to inspect military maneuvers and to ease tensions between Bosnia and Herzegovina and Austria-Hungary.
Austria-Hungary’s Ultimatum
In response to the assassination, Austria-Hungary issued an ultimatum to Serbia on July 23, 1914, demanding that Serbia:
- Dissolve the Black Hand society
- Prohibit anti-Austrian propaganda
- Allow Austria-Hungary to investigate the assassination
- Extradite individuals involved in the assassination
Serbia’s Response
Serbia rejected the ultimatum, citing the impossibility of dissolving the Black Hand society, which was a legitimate organization in Serbia. Serbia also pointed out that the investigation of the assassination was a matter for the Serbian authorities.
Austria-Hungary’s Declaration of War
On July 28, 1914, Austria-Hungary declared war on Serbia. This was the first declaration of war in the chain of events that would lead to the outbreak of World War I.
The Russian Response
In response to Austria-Hungary’s declaration of war on Serbia, Russia, which was allied with Serbia, began to mobilize its military. This was seen as a direct threat by Austria-Hungary, which led to the Austro-Hungarian declaration of war on Russia on August 1, 1914.
The German Response
Germany, which was allied with Austria-Hungary, declared war on Russia on August 1, 1914, and on France on August 3, 1914. Germany’s invasion of neutral Belgium on August 4, 1914, led to the declaration of war by Britain on Germany.
The Chain Reaction
The chain reaction of declarations of war continued, with:
- Germany declaring war on Belgium and France on August 4, 1914
- Britain declaring war on Germany on August 4, 1914
- Russia declaring war on Germany on August 6, 1914
