Why did the black hand want archduke dead?

The Black Hand, a secret nationalist group in Serbia, sought to assassinate Archduke Franz Ferdinand of Austria-Hungary because they opposed Austro-Hungarian rule over Bosnia and Herzegovina, which Serbia viewed as part of its national identity. The archduke's visit to Sarajevo in 1914 was seen as a direct provocation, and they believed that his death would help further their goal of creating a greater Serbia. The assassination ultimately triggered a series of events that led to the outbreak of World War I.
