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.
Society was changing from rural (Country) to urban (City).
Explanation:
When the industrialization process started int he United States, the country started to change rapidly. Initially this process was not accepted the same everywhere, with the North embracing it while the South not being so fond of it but over time it took over all of the states.
The majority of the people lived in rural societies before the industrialization but once it started there was a massive shift of the population from the rural to the urban areas. This resulted in emptying of the rural areas and rapid increase in population and size of the cities. This happened first in the North, so huge cities rose like New York, Washington, Philadelphia, Chicago, Boston etc.
The South was slower in this process because it thought that the agriculture does the job for it economically. That quickly changed though with the change of policy of the country, so once the economic troubles started there was sharp demographic switch from the rural to the urban areas in this part of the United States.
The correct answer to this open question is the following.
Although the question is incomplete and does not refer to any specific war, we can assume that it refers to the end of the Civil War, when the Confederate General Robert E. Lee surrenders at the Appomattox, Virginia, after the victory of the Union Army led by General Ulysses Grant. The date: April 9, 1865. The two generals had great respect for each other and Grant showed his respect to Lee and had a conversation before signing the terms of the surrender. With the authorization of President Abraham Lincoln, the terms of the surrender were generous because Lincoln really wanted a long term peace and the unity of the nation. The Confederate troops had to turn in their weapons and were allowed to return to their homes.
I think the terms were correct because what was most important at the time was not punishment but unity. The war had killed many soldiers and caused so much damage and pain in the United States. So, Lincoln wanted unity and peace, and that is how he thought about these terms.
I'm pretty sure the answer is indigo. If I'm wrong then I apologize.
