The pages listed in this category are templates. This page is part of Wikipedia's administration and not part of the encyclopedia. Further template category notes This category contains pages in the template namespace. It should not be used to categorize articles or pages in other namespaces. To add a template to this category: If the template has a separate documentation page (usually called "Template:template name/doc"), add  [[Category:Princesses by marriage templates]] to the <includeonly> section at the bottom of that page. Otherwise, add  <noinclude>[[Category:Princesses by marriage templates]]</noinclude> to the end of the template code, making sure it starts on the same line as the code's last character.

This category collects templates which list princesses on the basis of their marriages into various royal lines.
