1. Governor: This is a widely used title for the chief executive of a colony or a province. Governors are often appointed by a metropolitan country or a centralized government to represent their authority and administer the colony.
2. Viceroy: A viceroy is a high-ranking representative of a sovereign or state who exercises power on their behalf in a colony or territory. Viceroys typically hold significant authority and act as the head of the colonial government.
3. Protectorate President: In some protectorates, the local ruler or the representative of the protecting power may hold the title of "Protectorate President." They oversee the administration of the protectorate while maintaining certain levels of autonomy for the indigenous population.
4. Resident: In certain colonial contexts, the chief representative of a governing power might be referred to as a "Resident." Residents exercise control over the internal affairs of the colony while ensuring the interests of the colonizing nation.
5. Colonial Secretary: Sometimes, the title of "Colonial Secretary" is used for the highest-ranking official in a colony, especially during the British colonial era. Colonial Secretaries oversee the colony's administration, coordinate with various departments, and ensure compliance with the policies set by the central government.
These titles may have different variations and additional context associated with them based on the historical period, geographical location, and specific colonial powers involved. Some colonies might also use unique titles specific to their local traditions and political systems.
