chunk: Now a powerful figure, Tamburlaine turns his attention to Bajazeth, Emperor of the Turks. He defeats Bajazeth and his tributary kings, capturing the Emperor and his wife Zabina. The victorious Tamburlaine keeps the defeated ruler in a cage and feeds him scraps from his table, releasing Bajazeth only to use him as a footstool. Bajazeth later kills himself onstage by bashing his head against the bars upon hearing of Tamburlaine's next victory, and upon finding his body Zabina does likewise.
  After conquering Africa and naming himself emperor of that continent, Tamburlaine sets his eyes on Damascus; this target places the Egyptian Sultan, his father-in-law, directly in his path. Zenocrate pleads with her husband to spare her father. He complies, instead making the Sultan a tributary king. The play ends with the wedding of Tamburlaine and Zenocrate, who is crowned Empress of Persia.
