TS – Have you ever wondered what happened to those departments that suddenly disappeared years ago? Or perhaps you are trying to find out which department does what Department ‘X’ used to do?
'Foreign Affairs' Visualisation
We have produced the first of a series of visual representations of how government departments change over time to help you access our records and sate your curiosity.
Why is this necessary? Well, The National Archives looks after government departments’ historical records and provides access to them. Departments are created and abolished, and their functions transfer frequently between them. Many of these changes take place at seemingly random points.
Users of our records often need to have an understanding of what changes take place, when, in order to find what they want. We aim to produce accurate representations of this specialist knowledge online.
This information exists in Discovery and colleagues here at The National Archives have unique insights into this specialist area. We hope that visualising this in both a striking and accurate way will open up access to this knowledge still further.
Last year, we gathered data about changes to departments since 1997 to support our Semantic Knowledge Base project. Displaying this graphically is a whole different challenge.

The best way to explain the title of this blog is to begin by quoting directly from the Hedgehog Street website:
“Through Hedgehog Street, we are asking people to become Hedgehog Champions to rally support from their neighbours and work together to create ideal hedgehog habitat throughout their street, estate or communal grounds.”
I saw this initiative on BBC Springwatch a while back, specifically, one simple thing we can all do to become Hedgehog Champions – link your garden. Again to quote the Hedgehog Street website:
“Hedgehogs travel around one mile every night through our parks and gardens in their quest to find enough food and a mate. If you have an enclosed garden you might be getting in the way of their plans. Hedgehogs have enough barriers to contend with such as roads and rivers that we can’t do much about. However we can make their life a little easier by removing the barriers within our control – for example making holes in or under our garden fences and walls for them to pass through. The gap need only be around 15cm in diameter and so should not affect your pets’ safety.”
The idea of doing something so simple to protect our cute friends is a nice one. We’re converting one garden into hundreds, and combined with more naturally occurring wildlife corridors, potentially thousands. This is what we’re doing when we link data, the gardens represent our data and datasets and the link we’ve created gives users and machines unrestricted access to navigate from one dataset to another. It’s an almost perfect analogy – an analogy which I hope will help to open up the concept to all our readers, technical and non-technical alike.
