What was the life like for the poor people in rome? how did the roman empire try to keep poor people loyal?

 Most Romans lived at home called "Insulae", which could have up to 7 floors. On the higher floors, which were in danger of being flooded by water leaks, lived the poor, who paid daily or weekly.

The rooms had no ventilation, lighting, bathrooms, and the poor could be evicted at any time. The first two floors were of people with higher financial status, who paid for housing annually and had rooms with windows. The rich lived in country houses, which were called domus. A domus was a large, comfortable house with library, bedrooms, kitchen, interior gardens, much like the way we live today.

the factors that the economies of the muslim empires prosper were:

1- land trade routes-located between three continents  

2- sea trade routes

trade contributed to the spread of muslim empires, and with that islamic culture led to a growing feeling of internationalism resulted in the transfer of technology, science, and other cultural forms.

changes in factors like average income and preferences can cause an entire demand curve to shift right or left. this causes a higher or lower quantity to be demanded at a given price. demand curves relate the prices and quantities demanded assuming no other factors change. it is important for consumers to know this information, because it is crucial for them to know what they can afford and can't afford. i hope this .
