Here lies the timeline of the history of The Lion and the Rose. Starting from the point of divergence in 1555, when Mary of England gave birth to Henry von Habsburg, and ending somewhere close to our timeline's modern age. Sit back and enjoy the timeline of The Lion and the Rose. Due to the Butterfly effect, the world as we know it becomes unrecognizable, and event after event from our timeline does not happen, building up and the result is a vastly different timeline. The timeline only includes "notable" events.
