Hello! During the Spain Golden Age, which was between the 16th and 17th centuries, the empire was based upon the mutual support of the Catholic church. Besides that, it's true to say that Spain became one of the greatest commercial power in Europe, with a centralized government, but it's wrong to say that the country turns on in a industrial potency, once there is no industry in early 17th. So, the incorrect one is: Spain became a leading commercial and industrial power in Europe. Hugs!
