author
A late-19th-century civil rights organization rather than a single writer, this group is best known for a forceful public appeal that challenged racial violence and political silence in the United States. Its surviving work offers a direct window into Black protest and advocacy at the turn of the century.

by Colored National League
Published records for this title credit Colored National League, which appears to have been an organization rather than an individual author. The group is associated with Open Letter to President McKinley by Colored People of Massachusetts, a public protest text issued in 1899.
That letter was presented through a mass meeting in Boston and called attention to racial injustice, mob violence, and the federal government's response to anti-Black persecution. Read today, it stands less as a personal memoir than as a collective political voice, speaking with urgency and moral clarity.
Because reliable biographical information about specific members is limited in the sources I found, the safest way to understand this author credit is as a historical civic body representing organized Black activism in Massachusetts at the end of the 19th century.
