Final answer:
The tensions that led to the assassination of Archduke Franz Ferdinand were primarily related to political climate and territorial disputes in Europe, specifically between Austria-Hungary and Serbia.
Step-by-step explanation:
The tensions that led to the assassination of Archduke Franz Ferdinand were primarily related to the political climate and territorial disputes in Europe at the time.
One of the main tensions was between Austria-Hungary and Serbia. Austria-Hungary, who considered Serbia a threat to its empire, made a series of demands for restitution from the Serbian government after the assassination. When Serbia refused, Austria-Hungary decided to invade, which activated the European alliance system. Russia sided with Serbia, France supported Russia, and Great Britain was allied with France.
Another tension was between Austria-Hungary and Germany. Germany was bound by its treaty obligations to support any action taken by its ally, Austria-Hungary. This further escalated the conflict and drew more countries into the war.
