I believe the answer is: naturalistic observation
Naturalistic observation is being done without any form of variable manipulation from the researchers. The purpose of such observation is to make the result of the study represent the actual condition as close as possible. Usually only applicable for qualitative data.
I believe that Tocqueville who wrote the book Democracy in America published in 1835 thought that a committment to the common good was essential to democracy because in a democracy it is not just about the rights of a particular individual but about the collective rights of all citizens by virtue of being human and having basic needs such as freedom (he criticized slavery) the need for education, health care and food and shelter.
Confucius was wanting to have an important government job but never actually did, instead he became a "teacher." His time period was rough so only the rich could afford education. He made his students pay for their education, however, he chose those who showed eagerness to learn. Soon after he thought about North China looking for a ruler who would follow his teachings but wasn't very successful.He returned home disappointed and when he died at 72, he believed his life was a failure.
I would choose "representative democracy" as the best answer- this is the most typical example for what you described
Some other forms would also qualify in some cases, for example The Vatican city (Theocracy and absolute ?monarchy?) also has an elective leader, albeit for life.
but "representative democracy" is best.
Examples of representative democracy: US, Germany, UK.
