Lists of Spanish-speaking countries throughout history

Question

Nowadays in the list of Spanish-speaking countries, there are 20 countries, a territory, and an unrecognized country. However, this list has been changed throughout history due to the territorial evolution as well as constitutional changes. This is my research of the main lists. I plan to create a reference article about it when I have enough reputation. This thread is also a chance for me to receive your opinions.
