The Eastern Roman Empire, or Byzantium, managed to survive much longer then the Western Roman Empire because of multiple factors.
Some of the most important factors are that Byzantium had a strong leadership. The hierarchy was well placed, and the policies of the empire were good and prosperous.
Also, Byzantium was very wealthy, controlled important trade roots, had very well developed agriculture, and produced lot of goods, thus making the empire economically strong.
The military was well payed, well equipped, well organized, and it was loyal to the crown.
It was a humiliating defeat that pushed Cuba into the arms of the Soviet Union.
After the end of WWI, the Treaty of Versailles was signed by the Allied Powers and forced upon Germany. In this treaty, Germany had to take full responsibility for starting the war and were forced to pay reparations. A reparation is an amount of money a country/individual must pay for damages they have caused. In this case, Germany had to pay for the damage they caused in other countries during World War I. The cost of these reparations were very expensive, leading to the rapid decline of the German economy.
