Portugal focused on expanding its African territories in the 1800s to compensate for losses elsewhere, establishing colonies in modern Cape Verde, São Tomé and Príncipe, Guinea-Bissau, Angola, and Mozambique. In the 1900s, Portugal entered World War I to protect Mozambique from German troops and began losing control of its colonies as decolonization movements gained support during World War II and the Cold War, when the US and USSR tried to increase their influence in Portuguese territories.
