It was then that so many of the old Greek places took the names we now see them called by in the map, and which were mostly given by the Venetian seamen.  They called the Peloponnesus the Morea, or Mulberry-leaf, because it was in that shape; they called the island of Eubœa, Negropont, or Black-bridge; the Ægean Sea, the Archipelago, or Great Sea; and the Euxine, the Black Sea, because it is so dangerous. The Greeks hated their new masters very much, and would not conform to the Roman Catholic Church.  A new Greek empire was set up in Asia Minor, at Nicea; and after the Latin emperor Baldwin had been lost in a battle with the Bulgarians, and great troubles swept away his successors, the emperors returned to Constantinople, under Michael Palæologus, in 1261, and drove out all the Franks, as the Greeks called the Western people, chiefly French and Italians, who had come to settle in their cities.
