Amazon Prime announces that their Lord of the Rings show is set during the Second Age

The Second Age lasted for 3441 years and ended with the downfall of Sauron's army when he was defeated by the Last Alliance of Elves and Men following the downfall of Númenor.
This age was characterized by the rise (eventually with increased insolence) of Númenor, the rise of Sauron in Middle-earth, the creation of the Ringwraiths, and the early wars of the Rings between Sauron and the Elves. The Ring of Power also came into existence during this period.
TL,DR: the show's ending would eventually tie-up with the prologue from the first movie.
