How big did the population of a territory have to become before it could elect its own lawmaking body?

Well, isn't that a lovely question! The population of a territory typically needed to reach a certain size before it could have its own lawmaking body. This number varied depending on the specific laws and regulations in place, but it was usually based on ensuring fair representation and effective governance for all the people living there. Just like when we're painting a happy little tree, balance and harmony are key to creating a beautiful landscape for everyone to enjoy.
