The last chapter allows you to compare two selected topics across the Czech Historical Atlas portal. This individual selection can serve the user to independently discover parallels and connections in the historical development of the Czech state.
You can select a map for a given half of the screen in the drop-down menu. In the Free compare tab you can open and compare any maps (except the maps from chapters 6 and 7). Selected maps can be viewed in the Synchronized compare tab with the synchronized shift of both windows in different scales.
