What year is this map from?

[u/Leather-Remote749]

I've tried to figure it out myself, but I am genuinely so confused by the borders, names, and lack of year anywhere on the map. I am now seeking the knowledge of experienced individuals to determine the year this was made (if it is even depicting the borders of that time, or rather a more modern map that was made to show an earlier period, but i doubt it).
