Why was arch juke franz fredinad assassinated?

Archduke Franz Ferdinand of Austria was assassinated on June 28, 1914, primarily due to rising nationalist sentiments and tensions in the Balkans. His visit to Sarajevo was seen as provocative by Serbian nationalists, particularly the group known as the Black Hand, who opposed Austro-Hungarian rule over Bosnia and Herzegovina. His assassination is often cited as the immediate trigger for World War I, leading to a series of alliances and conflicts between major powers.
