It supported further liberalisation of Latvian nationality law by granting citizenship to non-citizens who had lived in Latvia for at least 10 years.

The roots of the TSP lay within the moderate wing of Popular Front of Latvia, the Latvian independence movement of the late 1980s and early 1990s.

Its leader, Jānis Jurkāns, was the first Minister of Foreign Affairs of newly re-independent Latvia, from 1990 to 1992 when he had to leave the government for his stance on relations with Russia.

Together with other activists, Jurkāns founded the Harmony for Latvia (Saskaņa Latvijai - Atdzimšana Tautsaimniecībai) alliance, which won 13 seats in the 1993 parliamentary election.

From its foundation, the party was popular with ethnic Russian voters for its moderate views on the citizenship issue and official languages.
