Constructed Languages (Conlangs or Constructed languages) are languages that are fake, artificial, or made with real intents to make a unified language for Earth or a specific country.
Notable Conlangs include Pig-Latin, Quenya by Tolkien, Klingon by Marc Okrand, and Esperanto made by Ludwig Lazarus Zamenhof in 1887. Some are very detailed and include such things as dictionaries, grammar usage and noegraphies while others have only a dozen or so words.
The reasons are many for creating such languages with a heavy leaning over the last few years towards fantasy type games and movies. Some Conlangs have many speakers such as Esperanto which is a real working language with upwards of a million speakers and Klingon which is a fantasy based language with a few thousand speakers.
There is no really definitive source for an accurate History of conlangs. One can only really note that until Genesis 11:1-9 the Earth spoke one language then was confounded. Hence after this time one would have to learn someone elses language to communicate. Which after a time would have led to the meshing of two or more languages to create a working common language for Trade and such during the meetings of different cultures and groups. AKA Constructed languages.
One can also note the term pidgin or pigin which defines itself as a meshing of two or more
languages to form a working language. These would have been the first noted "constructed languages"
although probably un-written. Another form of "constructed" language was "sign language" use by
many peoples over time during chance meetings but became more refined around 1755 by
Charles-Michel de l'Épée "the father of the deaf". One should be aware that Native Americans were
using "sign" language prior to Europeans arriving in America as a common form of communication with
different tribal groups.
Reiterated, most of these early histories have no "written" records or examples therefore
would have no references other then a verbal history or rumor to go on.
more later, keep your pants on.....
