The Estonian Sovereignty Declaration was issued on 16 November 1988. By 1989 the political spectrum had widened, and new parties were formed and re-formed almost daily. The republic's Supreme Soviet transformed into an authentic regional lawmaking body. This relatively conservative legislature passed an early declaration of sovereignty (16 November 1988); a law on economic independence (May 1989) confirmed by the Supreme Soviet of the Soviet Union that November; a language law making Estonian the official language (January 1989); and local and republic election laws stipulating residency requirements for voting and candidacy (August, November 1989).
