What does colonisation mean?
Colonisation refers to the process by which a nation, people, or group establishes and maintains control over a foreign territory, usually through settlement, administration, and economic exploitation. Historically, it describes the expansion of powers such as Britain, France, Spain, and Portugal across the Americas, Africa, Asia, and Oceania from the fifteenth century onward. The word carries significant weight in contemporary discourse: in historical and political contexts it frequently evokes themes of conquest, displacement, and cultural domination, while in scientific fields such as ecology and microbiology it is used neutrally to describe how species or microorganisms establish themselves in new environments. Derived from Latin roots relating to farming and settlement, colonisation remains central to debates about empire, identity, reparations, and decolonisation, making it an essential term for understanding both world history and current affairs.
nounThe process by which a country, people, or organism establishes control over a foreign territory or environment, settling it and exploiting or occupying it. In biology, it also refers to the spread of a species into a new habitat.
- The establishment of political and economic control over a territory by a foreign power, typically involving settlement of its land.
- The spread and establishment of a species, organism, or microorganism in a new habitat or on a host.

"Historians continue to debate the long-term economic effects of European colonisation."
"Within weeks of the wound being exposed to air, bacterial colonisation of the tissue was evident."
Rarely used in the plural; when it appears, it typically refers to multiple distinct instances of settlement or biological establishment.
"Ancient Greece saw numerous separate colonisations across the Mediterranean and Black Sea."
Every continent except Antarctica has been colonised at some point in recorded history — and even Antarctica's status as the only uncolonised continent is protected purely by treaty.

Etymology of colonisation
Colonisation derives from the Latin noun 'colonia', meaning a settlement or landed estate, itself rooted in 'colonus', a farmer or tiller of soil — reflecting Rome's practice of planting citizen settlements in conquered lands. The word entered English via French 'colonisation' during the early modern period, gaining prominence as European overseas expansion accelerated from the sixteenth century onward. It shares its root with cognates such as 'colony', 'colonial', and 'cultivate' (from Latin 'colere', to till or inhabit).

How colonisation is actually used
In modern usage, especially in historical and postcolonial discourse, the word often carries strongly negative connotations due to its association with exploitation, dispossession, and violence. In scientific contexts (ecology, microbiology), it is neutral and descriptive. The spelling 'colonization' is standard in American English; 'colonisation' follows British conventions. Related terms like 'settler colonialism' have emerged in academic writing to describe specific forms of the process.
Easily confused with colonisation
