The International Week of Solidarity with the Peoples of Non-Self-Governing Territories will be observed globally from 25 May to 31 May 2026. Established by the United Nations General Assembly through Resolution 54/91 in 1999, the observance is aimed at supporting people living in territories that have not yet achieved full self-government. The week serves as a reminder that despite decades of decolonization efforts, several territories around the world are still waiting for complete political self-determination.
According to the United Nations, a Non-Self-Governing Territory is a territory “whose people have not yet attained a full measure of self-government.” These territories remain under the administration of another country, known as the administering power, which is expected under Chapter XI of the UN Charter to protect the interests and well-being of the people living there.
Why the Week of Solidarity Matters in 2026
The UN first created the list of Non-Self-Governing Territories in 1946 when eight member states — Australia, Belgium, Denmark, France, the Netherlands, New Zealand, the United Kingdom and the United States — identified 72 territories under their administration. Over the decades, many territories achieved independence through global decolonization movements. Between 1960 and 2002 alone, 54 territories attained self-government.
However, 17 territories still remain on the UN list today. These include Western Sahara, Guam, Gibraltar, Bermuda, Cayman Islands, Falkland Islands (Malvinas), Tokelau, American Samoa, French Polynesia, New Caledonia and others. Most are located in the Caribbean and Pacific regions.
The week highlights the right of these peoples to decide their own political future, preserve their cultural identity and maintain control over natural resources and land. The UN has repeatedly urged administering powers to protect the property rights and economic interests of these territories while also helping develop democratic institutions and self-governance.

Decolonization Remains an Ongoing Global Issue
The observance is also connected to the UN’s wider decolonization mission. Since 1990, the United Nations has declared four International Decades for the Eradication of Colonialism. The current and fourth decade runs from 2021 to 2030, showing that the issue remains active even in the modern world.
For many territories, the challenges are not only political. Climate change, economic dependency, tourism pressures and limited local decision-making continue to affect daily life. Small island territories are especially vulnerable to rising sea levels and external economic control.
The International Week of Solidarity 2026 therefore goes beyond symbolism. It reflects the continuing global debate around freedom, sovereignty, human rights and equal representation. The observance encourages governments, international organizations and civil society groups to support peaceful dialogue and meaningful progress toward self-determination.
