Why Do Americans Celebrate Thanksgiving? The History Behind the Holiday

Why do Americans celebrate Thanksgiving? For many families, the answer begins with a meal, a gathering of loved ones, and a moment to appreciate what they have. But the history behind this familiar November holiday reaches far beyond the dinner table.

Thanksgiving developed through centuries of harvest traditions, religious observances, presidential proclamations, and changing American customs. The well-known 1621 gathering at Plymouth is part of that history, but it was neither the beginning of giving thanks in North America nor the moment that established our modern federal holiday.

To understand why Americans celebrate Thanksgiving, we need to look at the people and events that shaped it, including the Wampanoag people, George Washington, Abraham Lincoln, and the Americans who worked to establish a shared national observance.

That history is more complicated than the version many of us learned as children. It is also more meaningful when we understand it fully. Thanksgiving has become an opportunity to consider gratitude, family, community, and the responsibilities that come with living alongside one another.

Thanksgiving Began Before the United States Existed

The idea of setting aside time to give thanks is much older than the United States. Across different cultures and generations, people have expressed gratitude for successful harvests, community support, religious blessings, and the changing seasons.

For Native peoples of North America, traditions of gratitude existed long before European settlement. The Wampanoag and other Indigenous nations practiced ceremonies and seasonal observances rooted in their relationships with the land, their communities, and their beliefs.

European settlers also brought customs of harvest festivals and religious days of thanksgiving. These traditions were not identical, and they did not originate from a single shared celebration.

The Smithsonian’s National Museum of the American Indian provides a valuable account of these traditions and explains why the familiar story of the first Thanksgiving needs a broader historical perspective. Readers can explore that history in its resource on Native perspectives and Thanksgiving.

Understanding these separate traditions matters. The holiday Americans recognize today developed over time, drawing on different practices and historical events rather than beginning on one particular day.

What Really Happened at the 1621 Thanksgiving Gathering?

In the fall of 1621, English colonists at Plymouth, in present-day Massachusetts, held a harvest celebration after surviving an exceptionally difficult first year.

The Wampanoag people had inhabited the region for generations. Their knowledge of the land, agriculture, and local conditions played an important role in the colonists’ survival. Relationships between the communities involved diplomacy, negotiations, and a mutual-defense alliance, not simply the uncomplicated friendship sometimes portrayed in schoolbook illustrations.

According to surviving English accounts, the celebration lasted three days. Ousamequin, also known to the English as Massasoit, and approximately 90 Wampanoag men attended. The Wampanoag contributed five deer, while the colonists had hunted birds and gathered their harvest.

The meal would have looked different from a typical modern Thanksgiving dinner. There is no reliable basis for imagining a table set with every familiar dish, from pumpkin pie to today’s assortment of casseroles.

Was the 1621 Feast Really the First Thanksgiving?

Not in the broad historical sense. Native communities had observed traditions of thanksgiving for generations, and European colonists held other religious and harvest observances before and after 1621.

The Plymouth gathering later became central to the American Thanksgiving story, particularly as nineteenth-century writers and public institutions gave it greater attention. The familiar image of Pilgrims and Native Americans sharing a peaceful holiday meal is a simplified interpretation of a much more complicated event.

It is also important to remember that cooperation between the Plymouth colonists and the Wampanoag did not lead to lasting harmony. Colonial expansion brought dispossession, conflict, and profound losses for Native communities.

Recognizing those realities does not require abandoning a modern family tradition. It means understanding the history with greater care and respecting the Native people whose story is part of it.

How George Washington Helped Establish Thanksgiving

Long before Thanksgiving became an annual federal holiday, American communities and individual states observed various days of thanksgiving.

After the Constitution took effect, the first federal Congress requested that President George Washington recommend a national day of thanksgiving.

On October 3, 1789, Washington issued a proclamation designating Thursday, November 26, 1789, for public thanksgiving and prayer.

The proclamation reflected the circumstances of the young republic. Americans had recently established a new constitutional government, and Washington called for gratitude while acknowledging the responsibilities of national self-government.

This was an important milestone, but it did not establish a permanent annual holiday on a fixed date. Subsequent proclamations and observances varied, and Thanksgiving remained closely connected to state and local traditions.

Washington’s proclamation was another step in the development of the holiday, not the final act in its creation.

Why Abraham Lincoln Made Thanksgiving a National Tradition

One of the most significant turning points in Thanksgiving history came during the Civil War.

In 1863, the United States was divided by a devastating conflict. Families were separated, communities faced enormous losses, and the future of the nation remained uncertain.

Against that backdrop, President Abraham Lincoln issued a Thanksgiving proclamation on October 3, calling for a national observance on the last Thursday of November.

Lincoln’s proclamation was not simply a celebration of a successful harvest. It encouraged gratitude during a period of suffering and asked Americans to remember people affected by the war.

The proclamation helped establish the precedent of a recurring Thanksgiving observance in late November, although the country remained divided and the holiday’s legal status developed further in subsequent decades.

Sarah Josepha Hale’s Campaign for Thanksgiving

Lincoln did not act in isolation. Sarah Josepha Hale, an influential editor and writer, had advocated for years for a consistent national Thanksgiving holiday.

Hale believed a shared observance could bring Americans together across state lines. On September 28, 1863, she wrote to Lincoln urging him to establish a fixed national celebration.

Just days later, Lincoln issued his proclamation.

The Library of Congress preserves Hale’s correspondence and explains how her sustained campaign helped shape the holiday in its account of the woman who helped put Thanksgiving on the calendar.

Her story is a reminder that American traditions are not shaped by presidents and legislators alone. Writers, community leaders, and ordinary citizens can also influence the customs a nation carries forward.

Why Is Thanksgiving on the Fourth Thursday of November?

Although Lincoln helped establish the late-November tradition, the date was not permanently fixed at that time.

For many years, presidents generally proclaimed Thanksgiving near the end of November. Then, in 1939, President Franklin D. Roosevelt moved the observance to the second-to-last Thursday, hoping to extend the Christmas shopping season during the country’s recovery from the Great Depression.

The decision created confusion. Some states followed Roosevelt’s proclamation, while others continued observing Thanksgiving on the final Thursday of the month.

Congress eventually resolved the dispute. In December 1941, Roosevelt signed legislation establishing the fourth Thursday of November as Thanksgiving Day, effective in 1942.

This distinction matters because the fourth Thursday and the last Thursday are not always the same. When November has five Thursdays, the holiday falls a week before the final one.

The National Archives documents the congressional action that established the date still followed today.

How Thanksgiving Traditions Changed Over Time

The holiday’s meaning and customs have continued evolving long after its date was settled.

Family Meals and Familiar Foods

For many Americans, Thanksgiving centers on preparing and sharing food. Turkey, stuffing, potatoes, cranberry sauce, and pie have become familiar parts of the celebration, although menus vary considerably from household to household.

Some families prepare recipes passed down through generations. Others bring dishes rooted in their regional backgrounds or cultural traditions. The food may be different, but the gathering often carries the same purpose: making time for people who matter.

Parades, Football, and Community Gatherings

Public celebrations, football games, and holiday parades have become recognizable features of modern Thanksgiving.

Not everyone participates in these traditions. For some households, the day is quiet and reflective. For others, it involves large family gatherings, neighborhood meals, travel, or community events.

These differences are part of the holiday’s character. Thanksgiving is a shared date on the calendar, but Americans do not need identical customs to find meaning in it.

Volunteering and Helping Neighbors

Thanksgiving can also be an opportunity to put gratitude into action.

Community meals, food donations, checking on neighbors, and offering practical assistance provide ways to recognize that not everyone experiences the holiday with the same resources or support.

Helping someone who may otherwise spend the day alone can be as meaningful as preparing an elaborate dinner.

What Thanksgiving Means in American Life Today

Thanksgiving is one of several American holidays that invite reflection on national history and shared responsibilities. Yet each holiday has a distinct purpose.

Our article on why Americans celebrate Labor Day examines the recognition of workers and their contributions. Likewise, understanding the difference between Veterans Day and Memorial Day helps explain two observances associated with military service and sacrifice.

Thanksgiving has its own history. It is not primarily a commemoration of independence or military service. It is a national observance centered on gratitude, even as Americans bring different perspectives to its origins.

For some Native Americans, Thanksgiving is also a time to reflect on the consequences of colonization, loss, and historical injustice. Others observe the day with their own family and community traditions. These experiences should not be treated as if they are all the same.

A thoughtful understanding of Thanksgiving leaves room for historical honesty as well as personal gratitude.

Gratitude carries greater meaning when it recognizes not only what we have received, but also what we owe one another.

That idea does not belong to a political party or a particular way of life. It can be practiced in families, neighborhoods, workplaces, and communities across the country.

Meaningful Ways to Observe Thanksgiving

There is no single correct way for every American household to celebrate Thanksgiving. Still, a few simple practices can give the day greater meaning.

• Make room for gratitude. Take a moment to recognize the people, opportunities, and support that have made a difference in your life.
• Learn the history. Share an accurate account of the holiday, including the experiences of the Wampanoag people and the later creation of the national observance.
• Include someone. Invite a neighbor, friend, or relative who might appreciate company.
• Offer practical help. Contribute food, volunteer when needed, or support a local organization serving the community.
• Respect different traditions. Not every household observes Thanksgiving in the same way, and some people approach the date with mixed feelings.
• Care for national symbols thoughtfully. If your family chooses to display the American flag during the holiday, our guide to American flag etiquette at home explains respectful display practices.

None of these practices requires an elaborate celebration. They simply encourage Americans to connect gratitude with thoughtful action.

Thanksgiving’s Lasting Place in American Tradition

Why do Americans celebrate Thanksgiving? The short answer is gratitude. The fuller answer is a history that stretches from Indigenous harvest traditions and colonial settlements through the founding of the republic, the Civil War, and twentieth-century legislation.

The holiday did not emerge fully formed from a single meal in 1621. It developed through generations of people who understood giving thanks in different ways and through a growing national desire for a common day of observance.

Today, Americans continue to shape Thanksgiving through the way they gather, remember, serve, and care for one another.

At America 2 Wear, we believe appreciating this country’s traditions also means being willing to understand their history. Gratitude and historical honesty can stand together.

The most enduring Thanksgiving traditions may be the simplest: remembering what matters, making room for others, and recognizing that a strong community is built through everyday acts of consideration and responsibility.
