An arms race occurs when two or more countries increase the size and quality of military resources to gain military and political superiority over one another. The Cold War between the United States and the Soviet Union is perhaps the largest and most expensive arms race in history; however, others have occurred, often with dire consequences. Whether an arms race increases or decreases the risk of war remains debatable: some analysts agree with Sir Edward Grey, Britain's foreign secretary at the start of World War I, who stated "The moral is obvious; it is that great armaments lead inevitably to war."
Dreadnought Arms Race
With the Industrial Revolution came new weaponry, including vastly improved warships. In the late nineteenth century, France and Russia built powerful armies and challenged the spread of British colonialism. In response, Britain shored up its Royal Navy to control the seas.
Britain managed to work out its arms race with France and Russia with two separate treaties. But Germany had also drastically increased its military budget and might and built a large navy to contest Britain’s naval dominance in hopes of becoming a world power.
In turn, Britain further expanded the Royal Navy and built more advanced and powerful battlecruisers, including the 1906 HMS Dreadnought, a technically advanced type of warship that set the standard for naval architecture.
