1990 Italian regional elections
The Italian regional elections of 1990 were held on 6 and 7 May. The fifteen ordinary regions, created in 1970, elected their fifth assemblies. Electoral system
The pure party-list proportional representation had traditionally become the electoral system of Italy; it was also adopted for the regional vote. Each Italian province corresponded to a constituency, electing a group of candidates. At the constituency level, seats were divided between open lists using the largest remainder method with a Droop quota. The remaining votes and seats were transferred at the regional level, where they were divided using the Hare quota and automatically distributed to the best losers in the local lists. Results summary

The Italian political spectrum, which had been quite static since World War II, began to change rapidly. Umberto Bossi's Lega Nord obtained a stunning result in the general election round, making major gains in the Lombard Regional Council to become the second largest party in that council. The Christian Democrats suffered hugely under League pressure in Northern Italy, but counterbalanced these negative results in Southern Italy. Throughout Italy, the Communists lost ground, with revolutions in the Eastern Bloc marking the final decline of the party. Secretary Achille Occhetto understood that an era was finished and prepared the transition of his group to social-democratic ideas. Despite these changes, all fifteen councils confirmed their respective political administrations. However, margins in Northern Italy were too close to allow stable leadership, beginning a period of fragmentation in those regions. By the time these councils expired in 1995, Italian politics had changed completely. Results by region
