Indigegration
An alternative to "colonization" (or "colonisation"), indigegration means a move to and an adaptation to a new country. It describes the act of immigrating to a new homeland, integrating with the local territorial ecosystems, and indigenizing oneself or one's community.
Whereas 'colonize'/'colonise' comes from the Latin root 'colo-' (meaning "to till, to cultivate the land (literal), to inhabit, to protect, to nurture, to worship, to honour", ultimately from Proto-Indo-European's *kʷel- “to move, to turn (around), to revolve around, and therefore to sojourn, to dwell”), "indigegration" combines the words 'indigenous', 'immigrate', and 'integrate'.

The Métis Nation is a French nation that indigegrated to the Red River Valley in what is now Manitoba, Canada. Likewise, Acadians were in the process of indigegrating into Dawnland within Mi'kma'ki, alongside the Mi'kmaw Nation, before they were expelled by the British. Indigegration stands in opposition to the possessive nature of colonization. We can choose to go colonize Mars, or we can indigegrate there.
