The1958 Italian general election was held inItaly on 25 May 1958.^[1] The number of MPs to be elected was calculated upon the population's size for the last time.

Minor changes were made to the electoral law in 1958, creating a system which would remain unchanged until its abrogation in 1993.

The pureparty-list proportional representation was definitely adopted for the Chamber of Deputies.Italian provinces were united in 32 constituencies, each electing a group of candidates. At constituency level, seats were divided betweenopen lists using thelargest remainder method withImperiali quota. Remaining votes and seats were transferred at national level, where they were divided using theHare quota, and automatically distributed to best losers into the local lists.

For the Senate, 237 single-seat constituencies were established, even if the assembly had 9 more members. The candidates needed a landslide victory of two thirds of votes to be elected: only 5 hoping senators reached this goal. All remained votes and seats were grouped in party lists and regional constituencies, where aD'Hondt method was used: inside the lists, candidates with the best percentages were elected.

After De Gasperi's retirement in 1953, Fanfani emerged as the anticipated successor, a role confirmed by his appointment as party secretary from 1954 to 1959.^[2] He reorganized and rejuvenated the national party organization of the Christian Democrats after the dependence on the church and the government which had typified the De Gasperi period.^[3]

Fanfani's activist and sometimes authoritarian style, as well as his reputation as an economic reformer, ensured that the moderates within the DC, who opposed the state's intrusion into the country's economic life, regarded him with distrust. His indefatigable energy and his passion for efficiency carried him far in politics, but he was rarely able to exploit fully the opportunities that he created. One politician once remarked: "Fanfani has colleagues, associates, acquaintances and subordinates. But I have never heard much about his friends."^[4]

The election gave similar results of five years before and, consequently, the same problems of political instability of thecentrist formula.Christian Democracy was polarized by a fraction which liked moreleftist politics, and another one which urged for arightist route. Party's secretaryAmintore Fanfani was in the first field, and called for a dialogue with theItalian Socialist Party, which had frozen its relationships with theItalian Communist Party after theHungarian Revolution. Fanfani led a year-term government, but the reaction of the conservative fraction gave the power toAntonio Segni, followed byFernando Tambroni who received a decisivevote of confidence by theneo-fascistItalian Social Movement. The MSI had been banned by any type of political power since its birth under the theory of theConstitutional Arch, which stated that any government or opposition party which had voted theItalian Constitution, had to refuse any relationship with fascist and monarchist forces, seen as anti-constitutional groups. Strikes and revolts causing some casualties erupted through the country, and Tambroni had to resign. Fanfani returned to the premiership, this time with an openlycentre-left programme supported by the socialist abstention. The government created themiddle school for workers' sons, and theENEL after theelectric energynationalisation.
