The first European countries to build empires in the Americas were Spain and Portugal. Spain established a vast empire across much of South and Central America, as well as parts of the Caribbean, following Christopher Columbus's voyages in the late 15th century. Portugal, primarily focused on Brazil, began its empire in the early 16th century. Both nations played crucial roles in the early colonization and exploitation of the New World.
There has never been an emperor of Europe. There have been emperors of European countries/empires, but not of Europe itself.
