Rise and Fall

The line graphs below illustrate the rise and fall of a kingdom or empire in Priestley’s New Chart of History.

To make the sparklines clear, each is individually normalized to its maximum as represented on the chart. Select empires from the left menu at left to compare their stories.

Control of Places

Each horizontal chart row represents a geographic place in the world. These are constant over time. Their names are at right. Priestley indicates the history of kingdoms and empires with lines on the chart, showing when different regimes came to dominate those geographic places. Two additional graphs here present alternate ways of viewing the histories of particular geographic place. The top graph displays in chronological order the names of each dominant regime, using font size to show to the length of reign. The bottom graph displays the same data in total years.

Click on the chart to select up to 5 places to compare. Hover over the graphs to reveal numerical data.
