It was your identity and place in society. Ancient Rome was a....'very'...class conscious.... society... much like 19th century Britain. Then, as in 1800's Britain there were...3 distinct....classes... the small elite connected ruling nobles...the 'patricians'.
The better off middle class merchants/ medium land owners....the 'equestrians'. The largest group the 'commoners' (plebeians) who although not well off middle class or elite aristocrat were 'full citizens' and had to be taken account of in the 3 layer system. In ancient Rome below that...there were lots of serfs and slaves with no say (as much like commoner servants/ workers in 19th century Britain).
The Roman Senate was at 1st all 'Patrician'...later...rich/ popular Equestrians were allowed but the Patricians always dominated. Lower class commoner citizens were called...'citizens' or 'commoners' in that language, which was a huge step above... slaves and serfs....But this biggest 'commoner' group lost power, influence and rights steadily and towards the end of the Empire ended up as 'serfs' and 'peasants' for the Middle Ages. 'Plebs'...(or Plebeian)...as a derogatory term....comes from British aristocrats of the 19th century (1800's) trying to insult British lower class or middle class people making their way to the top of British politics or riches by...comparing them to the lowest class of ancient Rome just above slaves/ serfs and whose ancestors were serfs and peasants.
P.S. In ancient Rome a Patrician family would always be 'patrician' and considered so despite their present lack of wealth as pedigreed aristocrats....but if their fortunes stayed at.... 'poor'....for a generation or two... they would be dropped.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
