A History of the Fight Against Human Trafficking: From Abolition to Modern Advocacy

When most people hear the phrase "human trafficking," they think of a modern crisis, something born of the internet, globalization, or contemporary organized crime. And while those forces have certainly shaped its current form, the exploitation of human beings for labor and sexual purposes is not new. What is new is our collective recognition of it as a crime, and the organized, sustained global movement to stop it.

That movement has roots stretching back more than two centuries. Understanding its history is essential to understanding both how much has been accomplished and how much remains to be done.

The Abolitionist Roots: 18th and 19th Centuries

The first organized effort to combat the trafficking of human beings emerged from the transatlantic slave trade abolition movement of the late 18th century. In Britain, William Wilberforce led decades of parliamentary advocacy that culminated in the Slave Trade Act of 1807, which prohibited the British slave trade. His work inspired similar movements across Europe and North America, laying the moral and legal foundation for everything that followed.

In the United States, figures like Frederick Douglass and Sojourner Truth, both formerly enslaved, gave voice to the human cost of forced servitude and helped build the public and political will that eventually led to the abolition of slavery following the Civil War. Their advocacy established a critical principle that would shape anti-trafficking work for generations: the testimony of those who have experienced exploitation is essential to any meaningful response.

"The abolitionist movement did not simply end slavery. It created the moral language and organizational infrastructure that every subsequent anti-trafficking effort has built upon."

The First International Agreements: 1899-1921

In the late 19th century, as the transatlantic slave trade ended, a different form of exploitation drew international attention: the trafficking of women and girls into forced prostitution across national borders. In 1875, the International Abolitionist Federation became what historians identify as the first formal organization dedicated specifically to fighting human trafficking, focusing on the protection of women from sexual exploitation.

By 1899, the International Bureau for the Suppression of Traffic in Women and Children was founded, bringing together governments and civil society organizations around a coordinated response. International conferences took place in Paris in 1899 and 1902. In 1904, the International Agreement for the Suppression of White Slave Traffic was signed as the first international legal agreement specifically addressing trafficking. It focused primarily on protecting migrant women and children from sexual exploitation.

1807 - British Slave Trade Act

William Wilberforce's decades of advocacy result in Britain prohibiting the slave trade, sparking a global abolitionist movement.

1875 - International Abolitionist Federation Founded

Widely recognized as the first formal organization specifically opposing human trafficking, with a focus on protecting women from forced prostitution.

1899 - International Bureau Founded

The International Bureau for the Suppression of Traffic in Women and Children is established, coordinating government and civil society efforts across borders.

1904 - First International Anti-Trafficking Agreement

Thirteen countries sign the International Agreement for the Suppression of White Slave Traffic, the first binding international instrument on human trafficking.

1919 - International Labour Organization Founded

The ILO is established to set international standards for working conditions, marking a pivotal step in recognizing and addressing labor exploitation globally.

1921 - League of Nations Convention

The International Convention for the Suppression of Traffic in Women and Children is signed under the League of Nations, expanding protections and definitions.

The Post-War Era and the United Nations: 1945-1990

Following World War II and the horrors of the Holocaust, the global community created a new framework for human rights. In 1948, the United Nations adopted the Universal Declaration of Human Rights, enshrining the inherent dignity and equal rights of all people. The following year, the UN adopted the Convention for the Suppression of the Traffic in Persons and of the Exploitation of the Prostitution of Others, consolidating previous international agreements into a single instrument.

Progress slowed through the mid-20th century, but the second wave of the feminist movement in the 1960s and 1970s brought renewed attention to sexual exploitation and trafficking. Advocates began more explicitly connecting trafficking to broader patterns of gender-based violence and economic inequality, laying the groundwork for the more comprehensive frameworks that would follow.

The Modern Movement Takes Shape: 1990-2000

Several high-profile cases in the 1990s dramatically accelerated public awareness and political will in the United States. In 1995, the El Monte sweatshop case in California revealed that 72 Thai garment workers had been held in conditions of slavery and debt bondage for eight years. The case shocked the public and led directly to the founding of the Coalition to Abolish Slavery and Trafficking (CAST) in 1998, the first organization in the United States dedicated exclusively to serving survivors of human trafficking.

In 1997, a case involving deaf Mexican workers forced to sell trinkets on New York City streets expanded the definition of trafficking beyond sex exploitation to include forced labor. These cases, along with growing international attention and advocacy from faith communities, women's organizations, and human rights groups, created the political momentum for landmark legislation.

The Trafficking Victims Protection Act: 2000

On October 28, 2000, President Clinton signed the Trafficking Victims Protection Act (TVPA) into law. It was the first comprehensive federal legislation in United States history to specifically address human trafficking. The TVPA established trafficking as a serious federal crime with severe penalties, created protections and services for survivors, and introduced the "T Visa" to allow trafficking victims to remain in the country and access services regardless of immigration status.

The law was built around three principles, commonly called the "3 P's": prevention, protection, and prosecution. That same month, the United Nations adopted the Protocol to Prevent, Suppress and Punish Trafficking in Persons, the first international agreement to acknowledge modern-day slavery as including men as well as women, and to extend the definition to forced labor, organ trafficking, and other forms of exploitation.

Why the TVPA Mattered

Before 2000, there was no specific federal crime called "human trafficking" in the United States. Traffickers were often prosecuted under laws covering kidnapping, prostitution, or immigration violations, charges that rarely captured the full scope of the crime or resulted in sentences proportionate to the harm caused. The TVPA changed that, and has been reauthorized and strengthened multiple times since, most recently in 2019.

The Rise of the Modern Anti-Trafficking Movement: 2000-Present

Since 2000, the anti-trafficking movement has grown exponentially in size, sophistication, and diversity. Organizations like Polaris Project, founded in 2002, built the infrastructure that would eventually become the National Human Trafficking Hotline, the primary reporting and resource line for the entire United States. Anti-Slavery International, founded in 1839, remains the world's oldest human rights organization and continues to be a leading global force against modern slavery in all its forms.

Faith communities have played a particularly significant role throughout this history. Research on the passage of the TVPA notes that faith-based advocacy organizations were among the most influential voices in building congressional support for the legislation. The moral clarity that faith communities brought to the issue, combined with their grassroots organizing capacity and community trust, has made them an enduring and important part of the anti-trafficking movement at every level.

Today, the landscape includes hundreds of organizations working across prevention, intervention, survivor services, policy advocacy, and research. The understanding of trafficking has deepened considerably, with greater recognition of labor trafficking, the role of online platforms in recruitment, and the importance of survivor leadership in shaping programs and policy.

What History Teaches Us

• Survivor voices are not optional. Every major advance in this movement has been shaped by the testimony and leadership of people with lived experience of exploitation.

• Legislation alone is not enough. Laws matter, but they require funding, enforcement, training, and community support to create real change.

• Faith communities have always been central. From William Wilberforce to the passage of the TVPA to grassroots ministries forming across the country today, communities of faith have been indispensable partners in this work.

• The work is never finished. Every era has produced new forms of exploitation and new challenges. The movement must remain adaptive, informed, and relentless.

EverHope Foundation stands in this long tradition. We are not the first, and we will not be the last. But we believe, as those who came before us believed, that the exploitation of human beings is never inevitable, and that organized, compassionate, persistent effort can and does change lives.
