Father Fyodor Niță, a graduate of the Chișinău Theological Seminary, was a friend with the Moldavian writer Constantin Stere, who convinced him to send his son Sergiu to study at the Law Faculty of the University of Iași.

[2][3] As minister for Bessarabia, he was the head of the initiative group who established the first Romanian language theater in Chișinău, on 10 October 1920.

Internal divisions caused the party to split, with one group led by Niță joining the People's League in April 1920.

[5] In 1925, during a visit to Chișinău, King Ferdinand I of Romania stopped at the residence of Niță (the second house on Sergei Lazo Street from Ștefan cel Mare Boulevard).

[1][dead link‍] Niță died on 3 March 1940 in Bucharest; he was buried in the Central (Armenian) cemetery in Chișinău.
