What were the defining characteristics of slavery in the mainland English colonies by the 1750s?

Answer

By the 1750s, slavery in the mainland English colonies was a legally enforced, racial system of chattel bondage in which enslaved Africans and their descendants were treated as property that could be bought, sold, and inherited. Enslavement was typically for life and hereditary through the mother, and colonial slave codes sharply restricted movement, assembly, marriage, education, and legal testimony. Labor was coerced through violence and surveillance (including patrols), and families could be separated by sale, with enslaved people having few enforceable rights against owners.

Explanation

What the question is asking

You are describing what made slavery a distinct institution by the mid-1700s, not just listing examples of harsh treatment. Focus on how the system was defined in law, how it was passed on, how labor was controlled, and how it was tied to race in the English mainland colonies.

Slavery as "chattel": people treated as property

By the 1750s, enslaved people were legally defined as property (chattel) in most colonies. That meant they could be:

Bought and sold in markets
Used as collateral for debts
Inherited and transferred through wills and estates

Lifetime and hereditary bondage

A defining feature was permanence.

Slavery was generally for life, not a temporary term of servitude.
Status was hereditary, commonly determined by the condition of the mother (often summarized by the rule $partus\ sequitur\ ventrem$). This ensured slavery reproduced across generations.

Racialization and legal slave codes

Colonial laws increasingly linked slavery to African descent and “Blackness,” creating a racial caste system. Slave codes typically:

Limited movement and required passes
Restricted assembly and travel
Curtailed marriage and family rights as legally protected institutions
Barred most forms of legal equality, such as testimony against whites in many jurisdictions

Coercion, surveillance, and vulnerability of families

The system relied on force and monitoring to maintain labor and control.

Violence and physical punishment were widely permitted and practiced.
Slave patrols and militia enforcement helped police enslaved communities.
Families were vulnerable because sale could separate spouses, parents, and children at an owner’s discretion.

Why these characteristics matter

Taken together, these features show slavery was not only an economic labor system but also a legal and racial order: permanent, inherited, and enforced by colonial governments and local institutions.
