This declaration corresponds to the flushright environment.  This
  declaration can be used inside an environment such as quote or in a
  parbox.

  Unlike the flushright environment, the \raggedleft command does not
  start a new paragraph; it simply changes how LaTeX formats paragraph
  units.  To affect a paragraph unit's format, the scope of the
  declaration must contain the blank line or \end command (of an
  environment like quote) that ends the paragraph unit.
