Overview

The Week of Solidarity with the Peoples of Non-Self-Governing Territories is observed from 25 to 31 May in connection with the United Nations decolonization agenda and the rights and aspirations of peoples living in territories that have not attained a full measure of self-government.

Its history reaches back to a differently titled solidarity week proclaimed in 1972. The current form was requested by the General Assembly in 1999, so the predecessor and successor phases should not be collapsed into one undifferentiated origin story.

Reviewed guide

Why it matters

The Week provides a recurring point for attention to self-determination, political status, economic and social development, cultural identity and the responsibilities of administering Powers under the UN Charter.

A responsible guide should describe the institutional decolonization framework accurately and avoid implying that all remaining territories have identical political circumstances or preferences.

History

In 1972, A/RES/2911(XXVII) proclaimed a predecessor solidarity week focused on colonial peoples of Southern Africa and Guinea (Bissau) and Cape Verde, beginning on 25 May, which the resolution identified as Africa Liberation Day.

In 1999, A/RES/54/91 requested the Special Committee on decolonization to observe annually the Week of Solidarity with the Peoples of Non-Self-Governing Territories, commencing with the week beginning 25 May 1999.

The current United Nations calendar presents the observance as 25–31 May each year.
