How did arms race lead up to World War 1?

The arms race leading up to World War I was characterized by the intense competition among European powers to build up their military capabilities, particularly in naval forces and artillery. Countries like Germany and Britain expanded their navies, while others increased their army sizes and weaponry. This militarization heightened tensions and fostered an environment of distrust and aggression, making diplomatic resolutions less likely. Ultimately, the arms race contributed to a volatile landscape that facilitated the outbreak of the war following the assassination of Archduke Franz Ferdinand in 1914.
