8. </span>Weakening of the Roman legions:  <span>Rome’s military was the envy of the ancient world. But during the decline, the makeup of the once mighty legions began to change. Unable to recruit enough soldiers from the Roman citizenry, emperors like Diocletian and Constantine began hiring foreign mercenaries to prop up their armies. The ranks of the legions eventually swelled with Germanic Goths and other barbarians, so much so that Romans began using the Latin word “barbarus” in place of “soldier.” While these Germanic soldiers of fortune proved to be fierce warriors, they also had little or no loyalty to the empire, and their power-hungry officers often turned against their Roman employers. In fact, many of the barbarians who sacked the city of Rome and brought down the Western Empire had earned their military stripes while serving in the Roman legions.

The period between 1870 and 1914 saw a Europe that was considerably more stable than that of previous decades. To a large extent this was the product of the formation of new states in Germany and Italy, and political reformations in older, established states, such as Britain and Austria. This internal stability, along with the technological advances of the industrial revolution, meant that European states were increasingly able and willing to pursue political power abroad.
Imperialism was not, of course, a concept novel to the nineteenth century. A number of European states, most notably Spain, Portugal and the Netherlands, had carved out large overseas empires in the age of exploration. However, the new technologies of the nineteenth century encouraged imperial growth. Quinine, for instance, allowed for the conquest of inland Africa, whilst the telegraph enabled states to monitor their imperial possessions around the world. When the value of these new technologies became apparent, the states of Europe began to take control of large swathes of territory in Africa and Asia, heralding in a new era of imperialism
