After the electoral failure of the coalition of the Galician People's Party and the Galician Social-Democratic Party, members of both decided to re-form the Partido Galeguista, convoking a conference in November 1978.

In the Spanish General and regional elections of 1979, the party formed a coalition called the Unidade Galega and supported a "Yes" vote in the referendum for the Statute that granted autonomy to Galicia in 1980.

At the Party conference in June 1981, the Partido Galeguista's policies took a right-wing turn, and Álvarez Gándara was chosen as president.

In the extraordinary assembly of February 1984, many members supported the merger of the party into the Galician Coalition.

After this, Manuel Beiras left the party and founded the Partido Galeguista (Nationalist).
