Historical continuity
There is no single absolute definition. The term commonly refers to peoples descended from the earliest known inhabitants of a region, especially where a later settler or migrating population became dominant.

An official observance since 2023
Identity, dignity, and living heritage
World Indigenous Peoples’ Day was established as an official event in the United Roman-Ruthenian Church and Pontifical Imperial State of Rome-Ruthenia in 2023.
The Roman-Ruthenian ethnic identity constitutes a unique ethno-religious minority and an indigenous population in areas throughout the world associated with its heritage. Yet this day celebrates all indigenous populations, throughout the world and throughout history, whose living traditions embody the true diversity of humanity.
Meaning and identity
There is no single absolute definition. The term commonly refers to peoples descended from the earliest known inhabitants of a region, especially where a later settler or migrating population became dominant.
Indigenous populations often maintain traditions and cultural traits associated with earlier inhabitants. Some also adopt customs of colonising or immigrant cultures without losing their legitimate identity.
Indigenous persons need not remain in a traditional territory or practise every ancestral custom. Communities may have migrated, been resettled involuntarily, or developed new forms of cultural continuity.
Because indigenous nations are often not the majority population, they may face challenges to sovereignty, culture, health, safety, and economic well-being.
Some estimates identify approximately five thousand indigenous nations or populations across every inhabited continent. Their experiences differ greatly, but each bears a distinctive history, memory, and contribution to the human family.
Across the centuries
Recognition of peoples rooted in a land long predates modern political terminology. The Greeks acknowledged peoples before them, whom they called the Pelasgians, although their precise identity remains uncertain and partly legendary. The first-century B.C. historian Dionysius of Halicarnassus concluded that the Pelasgians were themselves Greek.
Contemporary reference points
Modern international institutions use working descriptions rather than one universally binding definition. These descriptions emphasize historical continuity, distinct identity, cultural institutions, and attachment to ancestral lands or traditional habitats.
Indigenous communities, peoples, and nations are those that, having a historical continuity with pre-invasion and pre-colonial societies that developed on their territories, consider themselves distinct from other sectors of the societies now prevailing in those territories, or parts of them. They form at present non-dominant sectors of society and are determined to preserve, develop, and transmit to future generations their ancestral territories and ethnic identity.
Indigenous peoples have documented histories of resistance, interface, or cooperation with states, demonstrating their conviction and determination to survive with distinct sovereign identities. They have continued to adapt to changing circumstances while maintaining those identities.
Communities that live within, or are attached to, geographically distinct traditional habitats or ancestral territories, and identify themselves as part of a distinct cultural group descended from peoples present before modern states and borders were established.
