I can't get any 'category' loops to load.

Here is my work flow.

I create a page called category.php and placed the following code (exactly like this):

```
<?php
/*
 * Template Name: Category
 */

if (!defined('ABSPATH'))
    exit; // Exit if accessed directly
get_header();
?>

<?php while ( have_posts() ) : the_post(); ?>

<h1 class="entry-title"><?php the_title(); ?></h1>

<div class="entry-content">

<?php the_content(); ?>

<?php endwhile; // end of the loop. ?>

<?php get_footer(); ?>

```

I then created a page called 'Category' in the WP Admin and then selected the template for category.php and nothing - zero.

Why wouldn't this load posts that belong to the relevant category?

Thanks for all help with this...
