American Abolitionists and Antislavery Activists:
Conscience of the Nation

Updated January 15, 2018

l to r: Frederick Douglass, William Lloyd Garrison, Wendell Phillips


Slavery began in British North America in 1619.  Men and women of conscience began efforts to end slavery from the earliest days of the American British colonies and the beginning of the American Republic.  These men and women were both White and African American.  Many of these individuals have been forgotten.  They dedicated their lives to ending the evil institution of slavery, sometimes at the risk of their lives.  It is our hope to recognize the heroism of these individuals, so that they may have a place of honor in our country's history.  

The purpose of this website is to provide a comprehensive history of the abolition and anti-slavery movements in the United States, from the Colonial period until 1865.  This will include a social, political, and economic history of both slavery in America and its opponents. 

Featured in this site is an online encyclopedia of abolition and anti-slavery activism in the United States.  The encyclopedia includes verbatim entries from a number of well-known sources published in the eighteenth and nineteenth centuries.  This includes biographies of prominent abolitionists and other opponents of slavery.  The researcher will have an opportunity to read from original sources, as written by numerous authors. This will provide a unique opportunity to read authentic accounts of the anti-slavery movement.  Many of the authors included in this work are noted figures in American history.  Many were actually involved in the abolition and anti-slavery movements.  Some were noted period historians.

In addition, this site will provide an extensive list of individuals and organizations that worked to end slavery in the United States. 

This site will serve as a reference guide and point of departure for further research for both scholars and interested individuals.

We have just posted an illustrated list of prominent abolitionist leaders and antislavery activists.  Please take a look at this gallery of American heroes.  This will be the basis for a major traveling exhibit, which will be premiering in 2017.

We are presently updating our list of abolitionists and antislavery activists.  This list will include a brief biography of the individual, along with entries from The National Portrait Gallery of Distinguished Americans, published 1835-1839, and Appletons' Cyclopaedia of American Biography, published in 1888.  This site will also be adding historical biographical entries from the Encyclopaedia Americana, 1845.  We have done a comprehensive list of abolitionists and antislavery activists by profession and vocation, which has recently been updated.  Among the categories in this list are political leaders, including senators, congressmen, and other government officials who opposed slavery.  The list also includes jurists, lawyers, writers, educators, businesspersons, newspaper editors and journalists, clergy and others. 

In addition, we are adding a comprehensive list of antislavery organizations.  These will include organizational descriptions and rosters of leaders and important members in these organizations.  These will also have entries from contemporary historical works.

This website is a work in progress.  We will continue to update the contents.  We invite your comments and suggestions to make this the best and most accurate possible site.  This site is a not-for-profit endeavor and is supported largely by volunteer research.


This project was created in cooperation with the Center for Jubilee, Reconciliation and Healing, Inc., Patt Gilliard-Gunn, President.  The Center for Jubilee is a nonprofit organization in Savannah, Georgia.  The members of the Center for Jubilee are primarily African Americans who are the descendants of formerly enslaved people from Savannah and its surrounding areas.  The Center is planning a series of educational program and a historic traveling exhibit.

We would also like to thank the NiBlack-Freeney-McNish family and show our appreciation for their friendship and inspiration.  This family is descended from formerly enslaved individuals who were emancipated by General Sherman's army on November 22, 1864.

We would like to gratefully acknowledge the cooperation of the librarians and staff at West Virginia University, in Morgantown, West Virginia.  These individuals are Jessica Tapia, Martin Dunlap, and especially Autumn Summers.  They have helped us in the pursuit of this project to honor anti-slavery activists in America.  We are grateful for their help and cooperation.  The African American and anti-slavery collections at the West Virginia University Libraries are extensive and outstanding.
