Evolution Queen Anne Side Chair Spain and Portugal , 718 AD-Present. Spain, unlike Britain, never fell outside of history after the collapse of the Western Empire, which gives us a continuous record of rule from Rome through the Visigoths and beyond.Also, Spain underwent her own unique transformation in the trauma of the Islâmic conquest. The Visigoths were crushed and for almost three centuries a revived Christian kingdom. This was perplexing to the researchers, because common sense says that these mutations,
