At the point when Germanic tribes attacked into the Balkans, Gaul, and Spain, the Roman Empire had issues in enrolling enough officers to battle against the burdens from the tribes. In the mid-third century, the state was compelled to utilize Germans from outside the Empire to attack the influx of tribes. The troopers were just willing to work for pay since they didn't recognize Roman cultures or traditions nor did they have any devotion to the Empire.
        
             
        
        
        
Answer: it is thought that thousands of Europeans lived in Imperial China during the period of Mongol rule. These were people from countries traditionally belonging to the lands of Christendom during the High to Late Middle Ages who visited, traded, performed Christian missionary work, or lived in China. This occurred primarily during the second half of the 13th century and the first half of the 14th century, coinciding with the rule of the Mongol Empire, which ruled over a large part of Eurasia and connected Europe with their Chinese dominion of the Yuan dynasty Whereas the Byzantine Empire centered in Greece and Anatolia maintained rare incidences of correspondence with the Tang, Song and Ming dynasties of China, the Roman papacy sent several missionaries and embassies to the early Mongol Empire as well as to Khanbaliq (modern Beijing), the capital of the Mongol-led Yuan Dynasty. These contacts with the West were only preceded by rare interactions between the Han-period Chinese and Hellenistic Greeks and Romans.

The arms race changed the relationship between the democratic west and the Soviet Union and created an atmosphere of fear and national insecurity known as the Cold War. During the Cold War, the Communist and Democratic nations accumulated huge arsenals of nuclear weapons that could destroy entire regions of the Earth. From this mammoth amount of power and influence came distrust, accusations of treason, and an era of nationalism. Today, many of the weapons still exist and pose a large nuclear threat, causing both the West and the East to fear each other as well as the possibility of nuclear warfare.
