In short
Who colonized Cuba?
Spain, from 1511 to 1898, followed by United States military occupation and a protectorate under the Platt Amendment until 1934.
Cuba won its war against Spain and lost its sovereignty in the settlement: the Platt Amendment made the right of American intervention a clause of the Cuban constitution.

How rule changed in Cuba
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 |
|---|---|---|

| 1898–1902, with reserved powers to 1934 | US occupation and protectorate | 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.
