Why did Austria -Hungary originally want to do with the Black Hand?

Austria-Hungary initially sought to suppress the Black Hand, a secret nationalist organization in Serbia, due to its role in promoting anti-Austrian sentiment and supporting the independence of Slavic peoples. The assassination of Archduke Franz Ferdinand by a member of the Black Hand in 1914 intensified Austria-Hungary's desire to dismantle the group, viewing it as a direct threat to their empire's stability. Consequently, they sought to hold Serbia accountable, which ultimately contributed to the outbreak of World War I.
