Who provided the weapons for the assassination of franz ferdinand?

The weapons used in the assassination of Archduke Franz Ferdinand of Austria were provided by a group of Serbian nationalists known as the Black Hand. They received support from elements within the Serbian military and government, which aimed to promote the cause of Serbian nationalism and oppose Austro-Hungarian rule over Slavic peoples. The assassination, carried out by Gavrilo Princip on June 28, 1914, ultimately contributed to the outbreak of World War I.
