what are three defining characteristics of slavery in Imperial Rome?

Instructions:

Base your answer exclusively on the lectures, podcast, and primary sources. Write a brief 300-500 word essay with three components: 1) a thesis statement as the very first sentence, 2) a definition of “slave society” and at least two other key words from the lectures this week (Augustus and res publica are good options for providing context for your answer), and 3) evidence from the lecture and readings. Your response should include at least 3 of the sub-chapters from the primary sources (whichever you prefer — you do not need to read the entire document).You must include Chicago/Turabian footnotes in your essay. When citing the primary sources, you should be referencing the actual primary sources rather than the introductory section about slavery. See below for a model for your citations.

The world limit is strict, so do not include an introduction or conclusion. Do not write quotations longer than 10 words.
