Humanists International
Humanists International is an international non-governmental organisation championing secularism and human rights, motivated by secular humanist values. Founded in Amsterdam in 1952, it is an umbrella organisation made up of more than 160 secular humanist, atheist, agnostic, rationalist, skeptic, freethought and Ethical Culture organisations from over 80 countries.
Humanists International campaigns globally on human rights issues, with a specific emphasis on defending freedom of thought and expression and the rights of the non-religious, who are often a vulnerable minority in many parts of the world. The organisation is based in London but maintains a presence at the United Nations Human Rights Council in Geneva, the United Nations General Assembly in New York, and the Council of Europe in Strasbourg, among other international institutions. Its advocacy work focuses on shaping debates on issues associated with humanism, the rights of the non-religious, and promoting humanist attitudes to social issues.
Humanists International is particularly active in challenging blasphemy and apostasy laws around the world and at the UN. Its annual Freedom of Thought Report indexes the world's countries by treatment of the non-religious and their commitment to freedom of thought and expression. Working with its member organisations, it also helps to coordinate support for those fleeing danger from states which persecute the non-religious. It advocates a humanist approach to various social issues, contributing to bioethical debates and arguing in favour of sexual and reproductive health and rights, LGBT rights, children's rights and women's rights, and in opposition to slavery and caste discrimination.
Outside of its advocacy work, Humanists International functions as the democratic organ of the global humanist movement. It holds a general assembly each year and a World Humanist Congress usually every three years; the last General Assembly was held in Luxembourg in July 2025, and the next Humanist Congress in Ottawa, Canada in August 2026.
Humanists International works to stimulate the growth of humanism and freethought and the spread of Enlightenment values around the world by supporting activists to form effective organisations in their home countries. In 2022, the Humanists International general assembly unanimously adopted the Amsterdam Declaration 2022, which presents as "the official defining statement of World Humanism".
Its official symbol, the Happy Human, is shared with its member organisations worldwide.
Humanism as a life stance
In 2022, at the organisation's 70th anniversary General Assembly, delegates voted to replace the previous Amsterdam Declaration 2002 with the Amsterdam Declaration 2022.Previously, in 2002, at the organisation's 50th anniversary World Humanist Congress, delegates unanimously passed a resolution known as the Amsterdam Declaration 2002, an update of the original Amsterdam Declaration.
The Amsterdam Declaration 2002 defined Humanism as a "lifestance" that is "ethical", "rational", supportive of "democracy and human rights", insisting "that personal liberty must be combined with social responsibility"; it is "an alternative to dogmatic religion"; it values "artistic creativity and imagination" and is aimed at living lives of "fulfillment" through the powers of "free inquiry", "science" and "creative imagination".
In addition to the Amsterdam Declaration's "official statement of World Humanism", Humanists International provides a "Minimum Statement on Humanism":
Humanism is a democratic and ethical life stance, which affirms that human beings have the right and responsibility to give meaning and shape to their own lives. It stands for the building of a more humane society through an ethic based on human and other natural values in the spirit of reason and free inquiry through human capabilities. It is not theistic, and it does not accept supernatural views of reality.
Member Organisations of Humanists International are required according to its membership regulations to have objects that are "consistent" with this understanding of Humanism.
Other major resolutions
At the World Humanist Congress in 2005, in France, the General Assembly adopted The Paris Declaration 2005, on state secularism, which states:There can be no freedom of conscience when religions rule societies. Secularism is the demand for equal rights for those who belong to any religion as well as for those who belong to none... For IHEU and its member organizations, the State must be secular, that is, neither religious not atheist. But demanding genuine democratic equality, recognized by the Law, between believers and humanists does not mean that the member associations of IHEU treat all philosophical points of view equally. We have no duty to respect irrationalism, however ancient its origins. True Humanism is the flourishing of freedom of conscience and the methods of free inquiry.In 2007, in an "unprecedented alliance" of the International Humanist and Ethical Union, the European Humanist Federation and Catholics for Choice, launched the Brussels Declaration, a secular response to a proposed Berlin Declaration, under which the amended EU Constitution would have made references to "God" and the "Christian roots of Europe". It made specific reference to policy positions on equality and human rights for different minority groups, concluding: "The principles and values on which European civilisation is founded are once again under threat. We call upon the people of Europe and all who care for freedom, democracy and the rule of law to join us in promoting and protecting them."
At World Humanist Congress 2011, in Norway, the Humanists International General Assembly adopted The Oslo Declaration on Peace, which concludes: "We urge each of our member organizations and Humanists globally to work for a more peaceful culture in their own nations and urge all governments to prefer the peaceful settlement of conflicts over the alternative of violence and war."
At World Humanist Congress 2014, in the United Kingdom, the Humanists International General Assembly adopted The Oxford Declaration on Freedom of Thought and Expression, which asserts: "Freedom of thought implies the right to develop, hold, examine and manifest our beliefs without coercion, and to express opinions and a worldview whether religious or non-religious, without fear of coercion. It includes the right to change our views or to reject beliefs previously held, or previously ascribed. Pressure to conform to ideologies of the state or to doctrines of religion is a tyranny."
In 2017, Humanists International held a special conference on threats to humanism and liberal democracy from rising authoritarian populism and extremism as part of its general assembly in London. At the following general assembly in Auckland, New Zealand, in 2018, Humanists International members agreed The Auckland Declaration on the Politics of Division, which condemned a recent global resurgence of demagogy, "exemplified in a new generation of so-called "strong men" politicians, who purport to stand up for popular interests, but who are eager to diminish human rights and disregard minorities in order to gain and retain power for their own ends". The Declaration commits humanist organisations "to addressing the social causes of the politics of division: social inequality, a lack of respect for human rights, popular misconceptions about the nature of democracy" and affirms the "values of democracy, rule of law, equality, and human rights."
In 2019, Humanists International members unanimously passed the Reykjavik Declaration on the Climate Change Crisis, acknowledging the scientific consensus on anthropogenic climate change committing the international humanist movement to "foster a social and political commitment to urgent action and long-term policymaking to mitigate and prevent climate change."
In 2025, the humanist community passed the Luxembourg Declaration on Artificial Intelligence and Human Values, committing to upholding and promoting ten "principles" for ethical adoption of artificial intelligence, offered as a summation of the humanist community's stance on AI and as a contribution towards global regulation of artificial intelligence and AI alignment efforts. The statement was adopted with input from global thought leaders in artificial intelligence, including Kate Devlin.
Organisation
Founding in 1952
Five Humanist organisations—the American Ethical Union, American Humanist Association, British Ethical Union, Vienna Ethical Society and the Dutch Humanist League—convened a founding congress in Amsterdam in August 1952, establishing the International Humanist and Ethical Union. Delegates adopted five resolutions, including a statement of the fundamentals of "modern, ethical Humanism" that became known as the Amsterdam Declaration.Development and later history
Early IHEU congress resolutions linked the organisation to post-war internationalism, including commitments aligned with United Nations human-rights ideals and an intention to seek NGO relations with UNESCO. In 1965, the board formulated ten characteristics describing what "ethical humanism" stood for; the text was adopted at the 1966 congress and later became known as the "Paris statement".In the 1990s, the organisation developed baseline texts intended to be usable across a diverse membership. A "Minimum Statement on Humanism" was adopted in 1991 and revised in 1996. The organisation also professionalised parts of its administration and opened a London office in February 1997. By its first 50 years, the IHEU had grown to include more than 100 member organisations and was headquartered in London.
The IHEU was granted special consultative status with the United Nations Economic and Social Council in 2000. In 2012, the organisation began publishing the Freedom of Thought report on discrimination against atheists and other non-religious people.
At its 2017 General Assembly, delegates passed a resolution mandating a change of name from the International Humanist and Ethical Union and directing the Board to oversee a transition to a revised organisational identity. In February 2019, Humanists International was adopted as the organisation’s operating name and brand, replacing the longer IHEU name with a shorter public identity for its international federation of member organisations.
The organisation continues to operate through separately incorporated entities. In the United States it operates as Humanists International Inc. In the United Kingdom, a charitable company incorporated in November 2020 was initially registered as Humanists International and later renamed Humanists International 2020. The UK entity is registered with the Office of the Scottish Charity Regulator as charity SC050629.
