1990 Andalusian regional election

The candidate for the PSOE, Manuel Chaves, was invested as President of the Regional Government of Andalusia for the first time, after winning the election with an absolute majority of seats.

He would remain in the presidency of this autonomous community for the longest period of time than any of his predecessors, not stepping down from office until 2009.

[1] Voting for the Parliament was on the basis of universal suffrage, which comprised all nationals over 18 years of age, registered in Andalusia and in full enjoyment of their political rights.

The 109 members of the Parliament of Andalusia were elected using the D'Hondt method and a closed list proportional representation, with an electoral threshold of three percent of valid votes—which included blank ballots—being applied in each constituency.
