The Regions of British Colonies

By the early eighteenth century, the British mainland colonies had divided into four sharply different regional societies. Climate, soil, and access to navigable rivers steered each region toward its own economy: subsistence farming and the sea in New England, tobacco in the Chesapeake, wheat and milling in the Middle colonies, and rice and indigo plantation slavery along the southern Atlantic coast. Religion and politics tracked the same regional lines. This lesson uses the Comparison reasoning process to set the four regions side by side and to test the geographic determinism that explains so much of their early development.

Learning Objectives

By the end of this lesson, students will be able to:

  • Identify the four British colonial regions (New England, the Chesapeake, the Middle colonies, and the Southern colonies) and the colonies that belong to each.
  • Compare the economies of the four regions and account for the role of climate, soil, and topography in shaping each regional economy.
  • Compare the religious and demographic profiles of the four regions, including Puritan New England, Anglican Chesapeake and Southern colonies, and the multi-denominational Middle colonies.
  • Compare the political institutions of the four regions, including New England town meetings, the Virginia House of Burgesses, and the proprietary assemblies of the Middle colonies.
  • Use Skill 3.A (Comparison) to identify both similarities and differences across the four regions and to assess the explanatory weight of geographic determinism against religion, founding charter, and labor supply.

Key Concepts

By the early eighteenth century, the British mainland colonies had grown into four regional societies that shared a common imperial framework but differed sharply in nearly every other way. Across all four, environmental conditions, founding intentions, and labor systems combined to produce distinct economies, religious cultures, and political institutions. The College Board CED organizes this story under five Key Concept statements (KC-2.1.II.A through KC-2.1.II.E), each devoted to one regional pattern, plus a fifth that captures the unusually participatory political life common to most of the colonies.

The Chesapeake colonies (Virginia, founded at Jamestown in 1607, and Maryland, founded in 1632) and the colonies of North Carolina built their economy on the export of tobacco, a labor-intensive cash crop that thrived in the deep, navigable river valleys around Chesapeake Bay. The first generation of Chesapeake planters depended on white indentured servants, drawn from the surplus laboring population of England under the Virginia headright system, which granted fifty acres of land to anyone who paid the Atlantic passage of a worker. After about 1680, after Bacon's Rebellion and the decline of English servant migration, planters turned to enslaved Africans, and the Chesapeake hardened into a society organized around tobacco plantations, an Anglican planter gentry, and a representative assembly called the House of Burgesses, founded in 1619 (KC-2.1.II.A).

The New England colonies of Massachusetts, Connecticut, Rhode Island, and New Hampshire took shape during the Great Migration of the 1630s, when roughly twenty thousand Puritans arrived in family groups intent on building a godly society on Calvinist lines. Short growing seasons and rocky, glaciated soil made plantation agriculture impossible, so families practiced subsistence farming, raised mixed crops and livestock, and turned to the sea for fishing, whaling, and shipbuilding, which became the foundation of the regional economy. Religion and government were intertwined: each town gathered around a Congregational church, and adult male freemen met in regular town meetings to elect officers, set local taxes, and decide community matters, producing one of the most participatory political forms in the eighteenth-century world (KC-2.1.II.B).

"Distinctions developed among the colonial regions in their political institutions, religious practices, economies, and the nature of their relationships with neighboring American Indians."AP USH CED, KC-2.1.II (paraphrased)

The Middle colonies of New York, New Jersey, Pennsylvania, and Delaware sat between New England and the Chesapeake on a fertile plain crossed by the Hudson, Delaware, and Susquehanna rivers. Wheat agriculture supported family farms rather than large plantations, and the Middle colonies became the principal exporters of cereal grains and milled flour to the West Indies and southern Europe. Their distinctive feature, however, was demographic. Beginning under Dutch rule and accelerating after William Penn opened Pennsylvania in 1681, the region drew an unusually wide range of European migrants: Dutch Reformed and English Anglicans in New York, English Quakers and German Lutherans and Pietists in Pennsylvania, Scotch-Irish Presbyterians along the western frontier, and French Huguenots and Sephardic Jews in the port cities. Pennsylvania in particular advertised religious freedom across the German-speaking world, and Philadelphia became the largest city in the British colonies and the most religiously and ethnically tolerant urban center in the Atlantic world (KC-2.1.II.C).

The Southern colonies of South Carolina, North Carolina, and (after 1732) Georgia, together with the British plantations in the Caribbean, used the long growing seasons and tidal swamps of the southern Atlantic coast to build plantation economies centered on rice, indigo, and (in the West Indies) sugar. Unlike the Chesapeake, the Southern colonies depended on the labor of enslaved Africans from the moment of founding rather than after a generation of indentured servitude. Many of the enslaved arrived from rice-cultivating regions of West Africa, and their agricultural knowledge underwrote the success of the South Carolina rice economy. By the early eighteenth century, South Carolina had a Black majority for much of the year, and the regional society was organized around large plantations, an Anglican gentry, and a Charleston merchant elite tied tightly to the West Indian and Atlantic slave trade (KC-2.1.II.D).

Across all four regions, distance from London and a Crown policy of salutary neglect through much of the early eighteenth century allowed colonial assemblies, town meetings, and elected legislatures to build self-governing institutions that were unusually democratic by European standards. New England towns ran their affairs through the town meeting; the Chesapeake elected the House of Burgesses; the Middle colonies seated proprietary and elected assemblies in New York and Pennsylvania; and South Carolina and Georgia answered to lower houses of assembly that fought regularly with appointed royal governors. Most adult white men with a property qualification could vote, a much wider electorate than anywhere in Britain. The resulting tradition of self-government would matter enormously when imperial reforms after 1763 collided with colonial assemblies that had grown used to running their own affairs (KC-2.1.II.E).

Four Regions Compared

The cards below set the four regions side by side on the dimensions that the AP exam tests most often. Comparison prompts on Period 2 routinely ask students to weigh two regions against each other on economy, religion, and political institutions, so the side-by-side framing matters as much as any single region's story.

The comparison points one direction. Environment did most of the work in setting the menu of regional economies, but it did not by itself decide which religion would dominate, who would migrate, or how political institutions would form. Geographic determinism is the right place to start a Comparison answer; founding charter, labor supply, and religion are what raise the answer to a complexity point.

Primary Source Excerpts

A comparison lesson works best with sources that document each regional pattern in the words of contemporaries. The four excerpts below align one-to-one with the four regions.

Sermon Hanover Historical Texts 1630 New England

John Winthrop, A Model of Christian Charity, 1630

"For we must consider that we shall be as a city upon a hill. The eyes of all people are upon us, so that if we shall deal falsely with our God in this work we have undertaken, and so cause him to withdraw his present help from us, we shall be made a story and a by-word through the world. We shall open the mouths of enemies to speak evil of the ways of God, and all professors for God's sake."

John Winthrop, the first governor of the Massachusetts Bay Colony, delivered this sermon to his fellow Puritan migrants either before or during the Atlantic crossing of the Arbella in 1630. The "city upon a hill" image captured what made New England different from the Chesapeake of the same decade. Massachusetts was founded as a religious community whose members covenanted with one another and with God. Town meetings, the Congregational church, and the social discipline of the New England town all flowed from the same Puritan covenant ideal that the sermon articulates.

Statute Library of Virginia 1619 Chesapeake

Proceedings of the Virginia General Assembly, 1619

"The most convenient place we could find to sit in was the Quire of the Church, where Sir George Yeardley, the Governor, being set down in his accustomed place, those of the Council of Estate sat next him on both hands except only the Secretary then appointed Speaker, who sat right before him; John Twine, clerk of the General Assembly, being placed next the Speaker, and Thomas Pierse, the Sergeant, standing at the bar, to be ready for any service the Assembly should command him."

The Virginia General Assembly met for the first time on 30 July 1619 in the church at Jamestown, with twenty-two elected burgesses representing eleven settlements. The meeting established the House of Burgesses, the first elected representative assembly in English America, and set a Chesapeake political pattern that would persist through the colonial period. The combination of a royal or proprietary governor and an elected lower house, drawn from the propertied planter class, became the model that South Carolina, Georgia, and most of the other British mainland colonies would later adopt.

Charter Avalon Project at Yale 1682 Middle Colonies

William Penn, Frame of Government of Pennsylvania, 1682

"That all persons living in this province who confess and acknowledge the one almighty and eternal God to be the creator, upholder, and ruler of the world, and that hold themselves obliged in conscience to live peaceably and justly in civil society, shall in no ways be molested or prejudiced for their religious persuasion or practice in matters of faith and worship; nor shall they be compelled at any time to frequent or maintain any religious worship, place, or ministry whatever."

William Penn, the Quaker proprietor of Pennsylvania, drafted the Frame of Government in 1682 as the colony's founding constitution. The religious-liberty clause excerpted here advertised Pennsylvania across Europe as a place where dissenting Protestants and Catholics could live and worship without legal disability. The clause helps explain why Pennsylvania drew so many German Lutherans, Pietists, Scotch-Irish Presbyterians, French Huguenots, and Sephardic Jews, and why Philadelphia by 1750 had become the most religiously diverse city in the British Atlantic world. The Middle colony pattern of ethnic and religious diversity that the CED captures in KC-2.1.II.C began with charters of this kind.

Herman Moll, A New and Exact Map of the Dominions of the King of Great Britain, 1715

Image reference: Engraved hand-colored map, roughly 100 by 60 centimeters. Depicts the British mainland colonies from Maine to Georgia, with detailed insets of Charleston harbor and the Carolina coast and a side panel showing the West Indian sugar islands. The map highlights tidewater rivers, plantations, and the Atlantic shipping routes that linked Charleston to Bristol and London. Public domain. Reproduce from the Library of Congress digital scan.

Herman Moll's map situates the southern Atlantic coast inside the wider British Atlantic plantation complex. The detailed Carolina inset shows the tidal rivers around Charleston that made rice cultivation possible, and the side panel makes clear that the South Carolina rice and indigo economy was tied to the West Indian sugar economy by ship, by capital, and by the slave trade. Maps of this kind helped London merchants and Crown officials picture the southern colonies as one node in a larger Atlantic plantation network. They also help students see why the Southern colonies developed differently from the Chesapeake despite their shared Anglican identity.

Discussion Questions

  1. (Comparison) Choose two of the four British colonial regions. Identify one major similarity and one major difference, and account for the role of environment in producing each.
  2. (Comparison) Both the Chesapeake and the Southern colonies built plantation economies that came to depend on enslaved African labor. Account for the differences in their founding labor systems, founding decade, and dominant cash crop. What does the comparison reveal about the limits of geographic determinism?
  3. (Comparison) The Middle colonies were the most religiously and ethnically diverse region. Account for two specific causes of that diversity, drawing on the William Penn excerpt and on the Dutch founding of New York. Why did similar diversity not develop in New England or the Chesapeake?
  4. (Causation) Account for how short growing seasons and rocky soil shaped New England's economy and society. How did the same conditions that ruled out plantation agriculture push the region toward town meetings, family farms, and shipbuilding?
  5. (Comparison) The Virginia House of Burgesses (1619), the New England town meeting, and the Pennsylvania assembly under the 1682 Frame of Government were three different forms of self-government in the British colonies. Compare any two of them on who could vote, who could serve, and what kinds of decisions they could make.

Classroom Activities

15 min

Four Regions Graphic Organizer

Distribute a four-column organizer with the rows Geography, Economy, Religion, Labor System, and Government. In small groups, students fill in each cell from the lesson reading. The class then debates which row is the most reliable predictor of the others.

25 min

Four Sources, Four Regions

Distribute the four primary sources from this lesson, one per group. Each group prepares a one-minute pitch arguing that its source captures the defining feature of its region. The class then votes on which region's source most clearly demonstrates geographic determinism, and which most clearly resists the geographic determinism frame.

20 min

Map Annotation

Project a blank outline map of the British mainland colonies. Working in pairs, students annotate each region with three labels: a major export crop, a dominant religious group, and a representative political institution. Each pair then defends one annotation to the class with a piece of textual evidence drawn from the lesson.

15 min

Counter-Factual Pair Share

Pose the following question to pairs: if Chesapeake soil and climate had supported wheat rather than tobacco, would the region have developed a Middle-colonies-style society? Pairs prepare a one-paragraph answer that uses at least two pieces of evidence from the lesson. The class compares answers and identifies the strongest non-environmental factor that pairs cited.

AP Practice Questions

Multiple Choice Sample ~ 2 min
1Question: Which of the following best accounts for the early development of subsistence farming, fishing, and shipbuilding as the dominant economic activities of New England in the seventeenth century?
  • (A) The Massachusetts Bay Charter prohibited the cultivation of cash crops for export to Britain.
  • (B) Short growing seasons and rocky glaciated soil ruled out plantation agriculture and pushed Puritan family farms toward mixed agriculture and the sea.
  • (C) The Crown reserved tobacco cultivation for the Chesapeake under the Navigation Acts of 1651.
  • (D) Enslaved African laborers refused to work in the New England climate.
  • (E) The Puritan founders of New England rejected commerce on theological grounds.

Correct: (B). The College Board CED traces New England's mixed economy of agriculture, fishing, whaling, and shipbuilding to the regional environment of short growing seasons, rocky glaciated soil, and deep coastal harbors. Puritan families practiced subsistence farming on small plots and turned to the sea for export commerce, producing the New England town economy that the CED captures in KC-2.1.II.B (LO 2.C; Skill 3.A).

Short Answer Question ~ 12 min · 1 page
2Question: Using your knowledge of United States history from 1607 to 1754, answer all three parts that follow.
  1. Identify ONE specific way the Chesapeake colonial economy differed from the New England colonial economy by the early eighteenth century.
  2. Explain ONE specific way the Middle colonies were more religiously and ethnically diverse than either New England or the Chesapeake.
  3. Explain ONE specific way the Southern colonies (South Carolina, North Carolina, and Georgia) differed from the Chesapeake in their founding labor system, despite the fact that both regions came to depend on enslaved African labor.

Scoring: 1 point for each part. Strong responses to part (a) might contrast Chesapeake tobacco plantations and indentured servitude with New England subsistence farming, fishing, and shipbuilding (KC-2.1.II.A and KC-2.1.II.B). Part (b) responses should name a specific cause of Middle colony diversity, such as the Pennsylvania religious-liberty clause of 1682, the Dutch founding of New York, or the migration of German Lutherans, Pietists, Scotch-Irish Presbyterians, and French Huguenots into the region (KC-2.1.II.C). Part (c) responses should note that the Chesapeake depended on white indentured servitude before about 1680 and shifted to enslaved African labor afterward, while South Carolina and Georgia depended on enslaved African labor from founding, in part because African rice-cultivation knowledge underwrote the rice economy (KC-2.1.II.A and KC-2.1.II.D).
