The significance of those journeys was that itinerant preaching created the first truly intercolonial mass public in British North America. By carrying one message along the whole seaboard, Whitefield and other traveling ministers synchronized religious enthusiasm, fueled a new commercial print market, and gave colonists an experience of belonging to a single audience.

The revivals known as the First Great Awakening ran roughly from the late 1730s into the 1740s. They arrived through two distinct channels. Settled pastors such as Jonathan Edwards preached revival to their own congregations in the Connecticut Valley. Traveling evangelists then carried the same message across colony borders. Whitefield's 1739–1740 tour from Georgia to New England turned that second channel into a continental phenomenon.

The mechanism: how a single sermon became an intercolonial event

The core mechanism was open-air, extemporaneous preaching aimed at large mixed crowds rather than seated congregations. This style worked because it changed who could hear and how the message traveled. Three features mattered.

First, audiences were unbounded by membership. Anyone could walk up. The elderly, the young, enslaved people, sailors, and the unaffiliated all stood in the same field. Second, the sermon was designed to be felt, not studied. Preachers used vivid images of judgment and personal conversion appeals. Third, printed notices announced the schedule in advance, so crowds could assemble at a named time and place.

The numbers behind that last feature explain the reach. Whitefield's open-air farewell sermon in Boston in 1740 reportedly drew an estimated 20,000 to 30,000 people, according to accounts collected by historians such as Thomas Kidd (2014). Among these figures, Boston's estimated population of roughly 16,000 to 17,000 in 1740 makes a crowd that size implausible as a literal count. The reported totals likely inflated audience estimates and probably counted passersby along the Common, and they show how quickly a revival sermon became a civic landmark. A skeptical rule of thumb for eighteenth-century crowd figures is to halve them before trusting them.

The deeper mechanism was repetition. Whitefield preached the same core message in dozens of towns on one itinerary. Each audience heard a version of what the previous town had heard. Colonists compared notes, letters, and printed accounts, and the message stayed consistent enough to feel like one event.

A plain-language summary: itinerancy converted local revivals into a shared experience, and print let that experience be compared and remembered.

Quantified context: one tour, twelve colonies, and a print boom

Whitefield made his first American tour from 1739 to 1740. He sailed from England to Georgia, preached his way north through the Carolinas, Virginia, and Pennsylvania, then reached New England. Afterward he returned south by a different route. In roughly a year he covered most of the settled seaboard, from Savannah to Portsmouth, New Hampshire.

Colonial population stood near one million by 1740. Most colonists lived within reach of a coastline or a navigable river. That geography made itinerancy practical. A preacher could follow coastal roads and packet routes, and word of his approach could precede him.

Print amplified everything. The first installment of Whitefield's Journals appeared in 1738, and American editions followed. Historians of the colonial press, including Frank Lambert (1994), document that Whitefield's publications became bestsellers in the colonies. The revival also triggered a pamphlet war. Supporters and critics published defenses and attacks within months. Religious controversy became a mass-market genre.

A comparison table makes the two revival channels visible.

Feature Settled pastor (Edwards model) Traveling evangelist (Whitefield model)
Audience Own congregation, mostly members Open crowds across denominations
Geography Single parish Multi-colony itinerary
Medium Sermon plus local print Sermon plus serialized journals and newspapers
Duration Sustained, local Intense, short visits
Effect on identity Strengthened one town Linked many towns into one audience
Main criticism Doctrinal anxiety Emotional excess and disorder
Legacy Theological writing Intercolonial celebrity and networks

The professional caveat is that revivals were not one uniform movement. Edwards critiqued excesses even while defending genuine conversion. Whitefield welcomed emotional response and drew far larger crowds. The same event looked different depending on which preacher's account you read.

The timeline of a movement, and the edge cases

A rough time course helps separate cause from consequence.

Period Event Why it mattered
1734–1735 Edwards reports a local revival in Northampton Established a template for revival narrative
1738 Whitefield's Journals begin publication Made the preacher a printed celebrity
1739–1740 Whitefield's first colonial tour Syndicated revival along the seaboard
1740 Open-air farewell sermon in Boston Demonstrated crowd scale and press coverage
1740–1742 Pamphlet war peaks Fixed the revival as a public controversy
1741 Edwards preaches "Sinners in the Hands of an Angry God" Canonized the sermon in revival memory
Late 1740s Revival energy declines and splits persist Denominational fragmentation outlasted the fervor

Edge cases matter for interpretation. New England's established Congregational order made itinerants controversial because they preached in parishes without permission. In the middle colonies, religious diversity meant revival sermons could reach people no single church served. In the South, Anglican establishment and enslaved populations made the audience different again. The significance of the journeys varied by region, so a single sentence can only name the common thread: a shared audience across those regions.

Misconceptions worth correcting

A common misconception is that the First Great Awakening was a single organization with a central plan. It was not. It was a wave of revivals with shared style and shared celebrities.

A second misconception is that the revival caused the American Revolution. The connection is loose at best. The revival trained colonists in voluntary association and public argument, which later served many causes. But historians including Jon Butler (1990) have argued that the awakenings were less unified and less decisive than popular memory suggests. Treat claims of a direct causal line to 1776 as overreach.

A third misconception is that only a few preachers mattered. Many itinerants carried the style. Denominational splits, especially among Presbyterians and Congregationalists, spread far beyond Whitefield himself.

Red-flag warnings for reading popular accounts:

Treat headline crowd totals as estimates, not counts. A revival's reach did not guarantee lasting conversion among attendees. Revivals produced conflict and schism, not just unity. Regional differences, not just doctrine, shaped who attended. Later retellings, especially from the nineteenth century, often padded the drama.

Practical actions for students and researchers

If you need to evaluate a claim about these journeys, use a staged check. Start with the primary evidence, then reconcile competing figures.

Date the claim to the correct tour or decade. Separate primary accounts from nineteenth-century retellings. Halve dramatic crowd figures before using them. Compare at least two regions, such as New England and the middle colonies. Distinguish Edwards-style congregational revival from Whitefield-style itinerancy.

The reconciliation rule is simple. When crowd counts conflict, use the lower figure and label it an estimate. When sources disagree about significance, name the specific mechanism, such as print, itinerancy, or denominational split, rather than a broad claim about national unity.

Limits of what can be concluded

The evidence supports a firm answer to the core question. Traveling preachers spread revival across all the colonies and created a shared public audience. Print connected that audience. Denominational fractures followed.

The limits matter too. No one counted a revival's lasting converts. Crowd estimates were inflated. Historians still argue about how unified the awakening was. The traveling preachers were significant less as a coordinated campaign than as a shared experience of hearing the same message in different colonies. That is the most defensible description of their significance, and it is one of the strongest influences on later colonial public life.
