The phrase "The Empire on which the sun never sets" (Spanish: El imperio en el que nunca se pone el sol) was first used to describe the Spanish Empire in the 16th century, and originates with a remark of Charles V, Holy Roman Emperor (Charles I of Spain), who declared "in my realm the sun never sets."
