What was the title of Jana Gana Mana in 1912?

Jana Gana Mana was not called anything else in 1912. It was originally written in 1911 and was published in the Bengali magazine "Bharati" in 1912.

It was originally titled "Bharoto Bhagyo Bidhata" which means "The Fate of India's Destiny" in Bengali.

The name "Jana Gana Mana" was given to the song later, though it's unclear exactly when the change occurred. The first time "Jana Gana Mana" was officially used as the title was in 1947 when it was adopted as India's national anthem.
