The first modern flushable toilet was invented in 1596 by Sir John Harrington who installed one for his godmother.
Most of the toilets in Medieval Europe were either holes in the ground, communal outhouses or chamber pots.
Only lucky and Wealthy ones have had the luxury of using a garderobe, which was a small rooms built adjacent to the wall of a medieval castle. The toilet would be connected to a vertical shaft that would run all the way down to the ground.
Occasionally some brave knights would conduct sneak attacks by entering the castle via the shaft connected to the garderobe. Throughout history, there have been a number of famous people who have died on the toilet. Several of them were stabbed from below while in the process of defecating.
