Morality plays emerged as a distinct dramatic form around 1400 and flourished until 1550. The most interesting morality play is The Castle of Perseverance which depicts mankind's progress from birth to death. However, the most famous morality play and perhaps best known medieval drama is Everyman. Everyman receives Death's summons, struggles to escape and finally resigns himself to necessity. Along the way, he is deserted by Kindred, Goods, and Fellowship - only Good Deeds goes with him to the grave.
