Like members of outsider groups before and since, this African-American elite considered education to be the key to full citizenship. They also embraced values of character and responsibility.

"A good, upright moral citizen, valuing temperance, a Protestant ethic of hard work, sobriety and all those kinds of inner values. Respectability then is the outward manifestation of character," says Peterson. "It’s in your appearance, how you dress, how you comport yourself, especially when you’re out on the streets of New York, and especially with whites. No loud, boisterous behavior but being utterly respectable and respectful."

'Black Gotham' explores the history and contributions of New York's black elite during the 19th Century.

That didn’t mean the status quo went unchallenged. Peterson's book describes salon-style meetings in the back of James McCune Smith’s pharmacy. Smith, who was one of antebellum New York’s most important black leaders, hosted lively debates about voting rights for blacks and the abolition of slavery.

Alliances with whites were often forged. And like white New Yorkers, many in "Black Gotham" also wanted to be rich - but success could be fleeting.

"You see black New Yorkers make tremendous gains and then lose. Gains in terms of entrepreneurship, finding a trade, finding a profession, setting down roots, buying property, and feeling they were at last becoming a genuine part of city life. They would refer to ‘color-phobia’ as ‘fast disappearing in our city.’ But then there would be a loss."
