The empire on which the sun never sets
The phrase "the empire on which the sun never sets" (Spanish: el imperio donde nunca se pone el sol) has been employed to describe empires so territorially extensive that it seemed to be always daytime in at least one part of their domains. Deriving from similar claims of universal rule associated with the ancient Roman and Persian empires, the modern concept originated in reference to the empire of Charles V. The phrase has long been used to define the Spanish Empire (in the 16th, 17th and 18th centuries) and the British Empire (in the 19th and early-to-mid 20th centuries).
