What variable is responsible for the default admin bar on top of every default Drupal theme?
It's stored in $page_bottom...you should also output $page_top to make sure you have a complete page:

&lt;/head&gt;
&lt;body&gt;
  &lt;?php print $page_top; ?&gt;
  &lt;?php print $page; ?&gt;
  &lt;?php print $page_bottom; ?&gt;
&lt;/body&gt;
&lt;/html&gt;
