What happened on July 291914?

Answer 1

On July 29, 1914, tensions escalated in Europe as Austro-Hungarian forces began mobilizing in response to the assassination of Archduke Franz Ferdinand, which had occurred a few weeks earlier on June 28. This mobilization was a key step toward the outbreak of World War I, as it increased fears of a larger conflict. The situation rapidly deteriorated, with countries taking sides and preparing for war, setting the stage for one of the deadliest conflicts in history.
