History of the Zeroth Law |
The Zeroth Law was initially discounted and taken for granted because scientists knew it was true. The science community later realized in order to create a logical thermodynamics system, they had to include the zeroth law.

Why Zeroth Instead of Fourth? |
This law presented a formal definition of temperature. Because of that, scientists believed that it should be at the top of the list of thermodynamic laws. Since the 1st, 2nd, and 3rd laws had already been established, renumbering all the laws would just lead to confusion. In order to avoid confusion, scientists named it the zeroth law.
