Mannerism
The new style first popped up in Florence and Rome, then the rest of Italy and, eventually, all over Europe. Mannerism, a phrase coined in the 20th-century, is what happened artistically during the Late Renaissance (otherwise known as the years between Raphael's death and the beginning of the Baroque phase in 1600). Mannerism also represents Renaissance art going out, as they say, not with a bang but, rather, a (relative) whimper.
