An autoimmune disorder, rheumatoid arthritis occurs when your immune system mistakenly attacks your own body's tissues. Unlike the wear-and-tear damage of osteoarthritis, rheumatoid arthritis affects the lining of your joints, causing a painful swelling that can eventually result in bone erosion and joint deformity. The inflammation associated with rheumatoid arthritis is what can damage other parts of the body as well.
Slavery in ancient Rome played an important role in society and the economy. Besides manual labor, slaves performed many domestic services, and might be employed at highly skilled jobs and professions.Teachers, accountants, and physicians were often slaves.Greek slaves in particular might be highly educated.uring the Pax Romana of the early Roman Empire (1stâ2nd century CE), emphasis was placed on maintaining stability, and the lack of new territorial conquests dried up this supply line of human trafficking. To maintain an enslaved work force, increased legal restrictions on freeing slaves were put into place.
During the years of the Roman Empire, the poor people were protected by the soldiers of the emperor. When the empire fell, there were no laws protecting them, so they turned to the lords to keep the peace and to act on their behalf. This willingness to be ruled by the lords led to the beginnings of feudalism. Some peasants were free, but most became serfs to the lord. This meant that they were required to stay with the land and pay very high rent to the lord.
