Which war broke out as a result of the assassination of Archduke Franz Ferdinand of Austria in 1914?

Okay, let's talk about the First World War. The early 20th century was a tense time in Europe, with various empires competing for power and influence. Think of it like a powder keg waiting for a spark. That spark came on June 28, 1914, when Archduke Franz Ferdinand, the heir to the Austro-Hungarian throne, was assassinated in Sarajevo. Austria-Hungary, backed by Germany, used this as an excuse to declare war on Serbia. Because of a web of alliances, this quickly escalated, drawing in countries like France, Russia, and eventually Britain. The Crimean War was much earlier, in the mid-19th century, and involved Russia against Britain, France, and the Ottoman Empire. The American Civil War was fought in the US, and the Second World War was a later conflict, starting in 1939. So, while the assassination was a single event, it triggered a chain reaction that led directly to the widespread conflict we know as the First World War.
