In short
Who colonized Algeria?
France. French forces took Algiers in 1830 and ruled Algeria for 132 years — legally as part of France itself — until independence on 5 July 1962 after a war that killed hundreds of thousands.
Algeria was the settler colony France refused to call one. From 1848 the northern territory was constitutionally part of France, which is precisely why decolonisation there became a war rather than a transfer of power.

How rule changed in Algeria
These periods describe different governing arrangements. The presence of a trading company, a military occupation and direct colonial government are not interchangeable; the notes preserve those distinctions where the record identifies them.
Political chronology
Rulers, periods and governing arrangements
| Period | Ruler or administration | Context |
|---|---|---|
| 1516–1830 | Regency of Algiers, under Ottoman suzerainty | See the chronology and context below. |
| 1830–1962 | France | Northern départements annexed as metropolitan France from 1848 |
| since 1962 | People's Democratic Republic of Algeria | See the chronology and context below. |
Periods may overlap where control differed by territory. A national independence date does not imply that every enclave or dependency changed status on that day.

Context
What the record shows
