Some areas, such as the Azores, Madeira and Macau, were deemed either impractical to decolonise or too close in ties to Continental Portugal to make independent. However, due to their distinct geography, economy, social and cultural situation, as well as historical aspirations of autonomy in Madeira and the Azores, the autonomous regions were formed.
Specifically, regions like the Azores, Madeira, and Macau were deemed either unattainable for independence or too closely tied to mainland Portugal to achieve sovereignty. However, their distinct characteristics, including geography, economy, social dynamics, and cultural identity, led to the creation of autonomous territories, particularly in Madeira and the Azores.
