A fleet carrier is intended to operate with the main fleet and usually provides an offensive capability. These are the largest carriers capable of fast speeds. By comparison, escort carriers were developed to provide defense for convoys of ships. They were smaller and slower with lower numbers of aircraft carried.
The First World War was sparked in the Balkans in 1914 when members of Mlada Bosna, a revolutionary organization with predominately Serbian and pro-Yugoslav members, assassinated the Austro-Hungarian heir Archduke Franz Ferdinand of Austria in Bosnia and Herzegovina's capital, Sarajevo.
Ethnic minorities chafed in Austria-Hungary, the final remnant of the Holy Roman Empire, but in 1914, it was reasonable to assume that Europe would remain at peace for many years. That assumption would turn out to be false. Europe in 1914 has often been compared to a powder keg: safe and secure until a fuse is lit. That summer, the assassination of an Austrian noble resulted in âthe Great War, the most destructive conflict then known to humankind. The city of Sarajevo is at the foot of the Balkan Mountains.
