Position Holder History

The Position Holder History tool generates a nice timeline table of everyone who has had a position held (P39) relationship with a particular position, and points out possible errors in the data.

In order to use the this tool, you might add, for example, the template:

{{PositionHolderHistory|id=Q14211}}

... to a page, and click the 'Refresh now' button to update the page.
