By the beginning of the 20th century, the city's population had reached 85,050 in 5 square miles (13 km2), making it the most densely populated city in the Southern United States. In 1900, the Census Bureau reported Richmond's population as 62.1% white and 37.9% black. Freed slaves and their descendants created a thriving African-American business community, and the city's historic Jackson Ward became known as the "Wall Street of Black America." In 1903, African-American businesswoman and financier Maggie L. Walker chartered St. Luke Penny Savings Bank, and served as its first president, as well as the first female bank president in the United States. Today, the bank is called the Consolidated Bank and Trust Company, and it is the oldest surviving African-American bank in the U.S. Other figures from this time included John Mitchell, Jr. In 1910, the former city of Manchester was consolidated with the city of Richmond, and in 1914, the city annexed Barton Heights, Ginter Park, and Highland Park areas of Henrico County. In May 1914, Richmond became the headquarters of the Fifth District of the Federal Reserve Bank.

Slavery and slaves were part of the social order; there were slave markets where they could be bought and sold. Many slaves were freed by the masters for services rendered; some slaves could save money to buy their freedom. Generally, mutilation and murder of slaves was prohibited by legislation. However, Rome did not have a law enforcement arm. All actions were treated as "torts," which were brought by an accuser who was forced to prove the entire case himself. If the accused were a noble and the victim, not a noble, the likelihood of finding for the accused was small. At most, the accused might have to pay a fine for killing a slave. It is estimated that over 25% of the Roman population was enslaved.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where in the Roman Republic could slaves be acquired?
Ah, so..
slave markets
