What was Franz Ferdinand and his wife Sofia doing in Serbia?

Archduke Franz Ferdinand of Austria and his wife, Sofia, were visiting Serbia in June 1914 as part of a state visit to the Austro-Hungarian provinces of Bosnia and Herzegovina. The visit aimed to strengthen ties with the region and demonstrate the empire's authority. However, their trip was overshadowed by rising tensions and nationalist sentiments, ultimately culminating in their assassination in Sarajevo, which sparked the outbreak of World War I.
