TheHistory of slavery in Michigan includes the pro-slavery and anti-slavery efforts of the state's residents prior to the ratification of theThirteenth Amendment to the United States Constitution in 1865.
Slavery in Michigan began centuries ago with the French when they began to trade with indigenous people in the 16th century. Detroit was founded at the beginning of the 18th century, at which point the number of enslaved people began to be recorded. While the records are incomplete and therefore under-report the numbers, historianMarcel Trudel counted 523 Native American and 127 Black enslaved people, for a total of 650 people, from the 18th and early 19th century Detroit.[1] The average life-span for enslaved Native Americans was 17.2 years, for Blacks, the average life span was 25.2 years.[1]
About 10% of early Detroit's population was made up ofindentured servants, who worked for five to seven years paying off the cost of their transportation to the New World or debts. Although they were free, their contracts could be bought and sold.[1]
When fighting other Native Americans, the victors captured women and children and took them into their communities.[2][3] They also captured people to replace warriors who died in battle. They did not consider slaves their property, although slaves were used as gifts during negotiations and trade.[4] Enslaved people were traded among other tribes. Subject to torture, many enslaved people had their ears cut off or their eyes gouged out. The children of enslaved indigenous people were not automatically classified as slaves.[1] After years of submission and serial rape, some women rose to have social acceptance and their freedom. Slavery may have been a practice for hundreds of years before contact with Europeans.[3]


When the French came to present-day Michigan, they had slaves and encouraged native people to trade enslaved people.[2] Most of slaves in present-day Michigan resided in Detroit or at the trading post at theStraits of Mackinac, later onMackinac Island.[6] Slavery was practiced in Detroit since its founding in 1701.[4] The settlement includedFort Ponchartrain, a government trade store on the Detroit River, andribbon farms.[7]
In 1709, the King of France issued a decree for theRaudot Ordinance of 1709, which legalized slavery. Both the French citizens and their slaves were Roman Catholics inNew France.Louis XV's ordinance of 1724 (Code Noir) required that slaves were to be educated and baptized. They had designated godparents who were free. The enslaved people's major life events—from birth through death—occurred within the auspices of the church. The role of the church meant that slaveholders did not have absolute dominion over their bondservants.[6] One quarter of Detroit's residents owned slaves in 1750.[4]
Fur traders used enslaved Native Americans and African Americans to operate boats, handle furs, grow food, cook, and clean.[8] About 25% of Detroit's populations were enslaved workers, but they produced one half of the town's primary products: beef, oats, and wheat.[1]
Fur traders who lived in the wilderness took Native American enslaved women as partners and companions,[4] some of whom became interpreters or paid subordinant traders.[7] Some farmers owned and worked alongside their slaves or hired men.[9]
John Askin, an 18th-century fur trader owned eight enslaved people.[8] One of them, anOdawa woman namedMonette, gave birth to three of Askin's children.[4]
Enslaved African Americans were also brought to Detroit by British settlers, some of them came from slave markets in New York.[8] Native Americans raided European settlements to preserve Native American territorial lands. They captured African Americans bondservants.[3] Native tribes often traveled with military soldiers and some officers owned slaves.[3] There were 73 slaves in Detroit in 1773, nine years later the number grew to 170.[8]
Free and enslaved Blacks were recruited to fight during theAmerican Revolutionary War, and the enslaved men were freed in return.[10] Blacks received veteran's benefits. TwoBlack Loyalists ofButler's Rangers gained their freedom and received land grants near Detroit.[10]
The current state of Michigan was part of theNorthwest Territory in 1787, when theNorthwest Ordinance made slavery illegal[11] with the clause "Neither slavery nor involuntary servitude shall exist in the territory".[8] Even so, there were still enslaved people living in Michigan until 1837.[11] French and British slaveowners in the Northwest Territory continued to own slaves due to loopholes in American law.[2] The ordinance was interpreted to mean that no more new slaves could be brought into the area.[12]
TheJay Treaty between Great Britain and the United States made it illegal to buy and sell slaves. The treaty did not change the status, though, of 300 existing slaves who lived in Detroit in 1795.[8] Catholic priests owned slaves and a slave helped build theBasilica of Sainte Anne de Détroit in 1800.[4] Enslaved people helped build the city of Detroit.[4]
Enslaved people generally slept on their slaveholder's kitchen floors.[4] Although there were some cases where they lived in a separate building, particularly if it was a family.[12] Subject to physical violence, some people were maimed. Women were subject to sexual violence.[4]
Some enslaved people were hired out to others, which allowed them freedom to walk in the streets of the city.[2][12] Somebondservants married into families of slaveholders.[2]
Elijah Brush was a slaveholder, who also argued for an enslaved family's liberty.[2][8] The owner ofGrosse Ile,William Macomb (c. 1751–1796) owned 26 bondservants, which was rare.[8][13] TheCampaus andWoodwards, leading families in Detroit, were also slave owners.[8] Other slave-owning families prominent in Detroit were the Abbott, Beaubien, Beaufait, Cass, Dequindre, Gouin, Groesbeck, Hamtramck, Livernois, McDougall, Meldrum, and Rivard families.[4]
There was a gradual reduction in slaves heading into the 19th century.[12] Some individuals weremanumitted voluntarily by their owners. Enslaved people found safety with Michigan Territorial residents, in Canada, or working along theGreat Lakes. John Askin's bondswoman Madeline and others fled him to work along the Great Lakes.[10]
Anti-slavery sentiment grew over time, so that by the 19th century, once an individual crossed the international border to or from Canada, people were free and were not returned to slavery. Slave catchers who searched for fugitives were harassed in Detroit. In 1806, an overseer was illegally tarred and feathered.[14] Following Detroit's devastating fire of 1805,the plan to rebuild included giving land grants to free and some enslaved Black people.[15]

Some filedfreedom suits, orwrits ofhabeas corpus, but few won their freedom through the courts, even when it was clear that people remained enslaved illegally. One case,In the Matter of Elizabeth Denison, Et. Al., was tried in 1807.[10] A farmer, William Tucker, owned members of the African American Denison family. He willed that Peter and Hannah should be freed after his and his wife's death. Their children were willed to the family of Tucker's brother. The Denisons initiated a ground-breaking lawsuit for the freedom of the children, citing the anti-slavery provisions of theNorthwest Ordinance.[8] JudgeAugustus Woodward and theMichigan Supreme Court ruled that the children—Elizabeth, James, Scipio and Peter Denison—should be enslaved.[8][10] The Denison family crossed into Canada, where they lived until Woodward later ruled that enslaved people who became free by living in Canada would not be returned to Michigan Territory slaveholders. DaughterLisette became a successful businesswoman and property owner.[8] In the meantime, there were two people from Canada who were released in 1808 as the result of their freedom suits. The following year, a boy named Thomas and a woman named Hannah were released.[10]
By 1810, there were 24 slaves in Michigan, 17 of whom were in Detroit.[12] Free and enslaved Blacks were recruited to fight during theChesapeake Crisis and during theWar of 1812, which released the enslaved men from the bonds of slavery.[10]
MayorJohn R. Williams used enslaved people for forced labor.[2][8] In 1817, Williams sought to purchase two Native American teenage children who he planned to hold as indentured servants until they were 30 years of age.[8] Although there were known slaves in the Michigan Territory in 1820, there were none recorded in the census.[12] TheDetroit Free Press, founded in 1831, supported slavery leading up to theCivil War.[4]
After freeing themselves in Kentucky,Thornton andLucie Blackburn arrived in Detroit in 1831.[11] In 1833, free and enslaved Blacks rioted against the imprisonment of the Blackburn family in what is called theBlackburn Riots. Rioters wounded the sheriff in the process of freeing the Blackburns and threatened to set the city on fire.[12]
An enslaved woman named Rachel was held as a slave in Michigan Territory before being sold to a new slaveholder inMissouri Territory. In 1834, she filed thefreedom suitRachel v. Walker, which was lost in the lower court. She appealed to theSupreme Court of Missouri, where she won the case, and her freedom, in 1836.[16]
Slavery was banned throughout the British Empire, including Canada, due to theSlavery Abolition Act 1833. Two years later, there were two slaves inMonroe County and one inCass County. Slavery was banned in Michigan Territory in 1835, with its firstConstitution of Michigan in the runup to statehood (1837).[14]
In 1832, the first anti-slavery society in Michigan was founded by theQuakerElizabeth Chandler in a meetinghouse inAdrian, Michigan.Laura Haviland became a member of the society.[11] TheMichigan Anti-Slavery Society was founded in 1836 inAnn Arbor, Michigan.[17]
George DeBaptiste was considered to be the "president" of the Detroit Underground Railroad,William Lambert the "vice president" or "secretary", andLaura Haviland the "superintendent".[18] TheSecond Baptist Church of Detroit, a stop on theUnderground Railroad, was organized by African Americans in 1836.[11] Freedom seekers crossed theDetroit River into Canada.[8]
Michigan became a state in 1837, and theConstitution of Michigan banned slavery.[11]Henry Bibb, who freed himself from slavery, became a resident of Michigan in 1842. He was the son of an enslaved woman and her master. He began to explain the ways in which exlaved people were treated in the South and encouraged enslaved people to "break your chains and fly for freedom".[11]
In 1847,Raiders from Kentucky came toCass County and tried to kidnap at least nine formerly enslaved people.Adam Crosswhite and his family, former enslaved people living inMarshall, were among those that they tried to capture (Marshall Crosswhite Affair).[11] ThePersonal Liberty Act of 1855 was passed by the Michigan legislature, which made it harder for enslaved people to be captured and returned to slavery.Sojourner Truth, a former enslaved woman and abolitionist moved toBattle Creek in 1857.[11]
By the time thatSojourner Truth moved to theBattle Creek area in 1857, she was a free woman, published author ofThe Narrative of Sojourner Truth, and a national speaker for the anti-slavery and women's movements.[19]
TheEmancipation Proclamation was issued by PresidentAbraham Lincoln in 1863. It freed enslaved African Americans in theConfederate States. The First Michigan Colored Infantry Regiment was formed in 1864 to fight in theCivil War. TheThirteenth Amendment to the United States Constitution of 1865 banned slavery.[11]
