Antonio Segni (Italian pronunciation: [anˈtɔːnjo ˈseɲɲi]; 2 February 1891 – 1 December 1972) was an Italian politician and statesman who served as 4th President of Italy from May 1962 to December 1964 and 34th Prime Minister in two distinct terms between 1955 and 1960.
A member of the centrist Christian Democracy, Segni held numerous prominent offices in Italy's post-war period, serving as Minister of Foreign Affairs, Interior, Defence, Agriculture and Education. He was the first Sardinian ever to become head of state and government. He was also the second shortest-serving president in the history of the republic and the first one to resign from office due to illness.
Antonio Segni was born in Sassari in 1891. His father, Celestino Segni, was a lawyer and professor at the University of Sassari, while his mother, Annetta Campus, was a housewife. He grew up in a well-off family, involved in Sardinian politics: his father served as municipal and provincial councilor for Sassari as well as deputy mayor during the early 1910s.
In 1913, Segni graduated with merit at the University of Sassari, with the thesis Il vadimonium, on civil procedure in Roman law. He completed his studies in Rome with Giuseppe Chiovenda, of which he became the favorite student; in the law firm of the jurist, he met Piero Calamandrei, with whom he built a close friendship that would last a lifetime.
When the World War I broke out, he was enlisted as an artillery officer. Discharged, after some months he continued his profession as lawyer, specializing in civil procedure. In 1920, he started his academical career as law professor at the University of Perugia.
During these years, Segni started his involvement in politics. In 1919, he joined the Italian People's Party (PPI), a Christian democratic party, led by Don Luigi Sturzo. In 1923, he was appointed in party’s national council. Segni run in the 1924 general election for Sardinia's constituency, but he did not succeeded in being elected. He remained a member of the PPI until all political organizations were dissolved by Benito Mussolini two years later in 1926. For the next 17 years Segni left political life, continuing to teach civil procedure and agrarian law at the Universities of Pavia, Perugia, Cagliari and Sassari, where he later served as rector from 1946 to 1951.
Early political career
In 1943, after the fall of Mussolini's fascist regime, Segni was one of the founders of the Christian Democracy (DC), the heir of the PPI. On 12 December 1944, he was appointed Undersecretary to the Ministry of Agriculture in the government of Ivanoe Bonomi.
Minister of Agriculture
In the 1946 general election, Segni was elected to the Constituent Assembly for the consistency of Cagliari–Sassari–Nuoro, receiving more than 40,000 votes. On 13 July 1946, he was appointed Minister of Agriculture in the government of Alcide De Gasperi. As minister, he primarily focused on the growth of agricultural production, functional to improving Italy's conditions after the end of the war. Segni tried to reform agricultural contracts, however, he was strongly opposed by conservatives and by many members of the DC too. The failure of this legislative proposal accelerated the timing of the development of the land reform.
The land reform, approved by the Parliament in October 1950, was financed in part by the funds of the Marshall Plan launched by the United States in 1947 and considered by some scholars as the most important reform of the entire post-war period. Segni's reform proposed, through forced expropriation, the distribution of land to agricultural laborers, thus making them small entrepreneurs and no longer subject to the large landowner. If in some ways the reform had this beneficial result, for others it significantly reduced the size of farms, effectively removing any possibility of transforming them into advanced businesses. However, this negative element was mitigated and in some cases eliminated by forms of cooperation.
Segni, who was a landowner, ordered the expropriation of most of his own estate in Sardinia. He became known as a "white Bolshevik" for his agrarian reforms. Modern historians assert that landowners were instead favored by Segni, and his decrees allowed them to reclaim land which had been granted to the peasantry by the preceding administration.
Minister of Education
As minister, he was particularly involved in the fight against illiteracy, in the improvement of teaching activities and in the construction of new schools around the country. However, he did not continue the important reforms started by his predecessor. He tried to implement the reform step by step, but encountered strong resistance, even in the ministries that were supposed to finance these measures. Segni proposed to replace the high school exam with an admission test to university, but it was rejected. His reforms, which also received various appreciations from the opposition parties, due to his secular idea of school which was very different from Gonella's one, were not ambitious as the ones of his predecessor.
The 1953 general election was characterised by changes in the electoral law. Even if the general structure remained uncorrupted, the government introduced a superbonus of two thirds of seats in the House for the coalition which would obtain at-large the absolute majority of votes. The change was strongly opposed by the opposition parties as well as DC's smaller coalition partners, who had no realistic chance of success under this system. The new law was called the Scam Law by its detractors, including some dissidents of minor government parties who founded special opposition groups to deny the artificial landslide to Christian Democracy.
The campaign of the opposition to the "Scam Law" achieved its goal. The government coalition won 49.9% of national vote, just a few thousand votes of the threshold for a supermajority, resulting in an ordinary proportional distribution of the seats. Technically, the government won the election, winning a clear working majority of seats in both houses. In July 1953, Segni was ousted from office in the newly formed government of De Gasperi. However, frustration with the failure to win a supermajority caused significant tensions in the leading coalition, and De Gasperi was forced to resign by the Parliament on 2 August. On 17 August, President Luigi Einaudi appointed Pella as new Prime Minister, who selected Segni as his Minister of Education.
Prime Minister of Italy
In April 1955, Giovanni Gronchi was elected new President of the Republic. After the election, a political crisis between Prime Minister Scelba and DC's leader Fanfani broke out. In July 1955, Scelba resigned from the office, and Segni received the task of forming a new cabinet. He started consultations with parties to explore the possibilities of forming a new coalition government, obtaining the approval of DC, Italian Democratic Socialist Party (PSDI) and Italian Liberal Party (PLI) and the external support from the Italian Republican Party (PRI). On 6 July, Segni sworn in as new Prime Minister. On 18 July, the government's program was approved by the Chamber of Deputies with 293 votes in favor and 265 against while, on 22 July, the Senate of the Republic approved the confidence vote with 121 votes in favor and 100 against.
Segni's first government is widely considered among the most important cabinets in the history of the republic. During his premiership, in 1955, Italy became a member of the United Nations (UN). While, in March 1957, Segni signed the Treaty of Rome, which brought about the creation of the European Economic Community (EEC), between Belgium, France, Italy, Luxembourg, the Netherlands and West Germany. The Treaty of Rome still remains one of the two most important treaties in the modern-day European Union (EU).
Segni had always been a strong supporter of European integration; according to him, in a world governed by great powers, the European unity was the only possible way to influence the world. He also strengthen relations with West Germany, becoming a close friend of Konrad Adenauer. As premier, he also had to face the complicated Suez crisis of 1956, in which he staunchly defended Italy's economic interests in the area, always bearing in mind the need to safeguard Atlantic and European solidarity.
During his premiership, he had often harsh contrasts with Amintore Fanfani. The secretary of the DC believed, in fact, that the government should have a more critical attitude towards the Anglo-French choices. Moreover, Soviet's brutal repression of Hungarian Revolution, in 1956, further widened the distances between Segni and Fanfani. Segni was contrary to an anti-communist legislative intervention, as Fanfani asked. The clash between the two leaders was so bitter that Segni threatened to resign. He noted in his diary: "The events of Hungary are unfortunately subjected to repressive political speculation. I refuse to speculate on them."
In domestic policy, Segni's government was particularly active in judiciary policies. A law established the National Council of Economy and Labor as well as the Superior Council of the Judiciary. However, the most important event of all was the official opening of the Constitutional Court of Italy.
In 1957, political tensions arose between President Gronchi and Foreign Affairs Minister Gaetano Martino, regarding government's foreign policy. In May 1957, the PSDI withdrew its support to the government and on 6 May, Segni resigned. On 20 May, Adone Zoli sworn in as new head of government.
After the premiership
As minister, he worked to represent the interests of the Italian armed forces, increasing wages and social securities for retired veterans, as well as strengthen military equipment and weapons. He also accepted NATO missile bases for atomic weapons, convinced that they were a necessary tool to ensure the defense of Italy more than a danger that exposed the country to possible reprisals.
In January 1959, a conspicuous group of Christian Democrats started voting against their own government, forcing Fanfani to resign on 26 January 1959, after only six months in power.
In February 1959, Gronchi gave Segni the task of forming a new cabinet and he officially sworn in as new Prime Minister on 15 February. Segni formed a one-party government, composed only by members of the Christian Democracy, which was externally supported by minor centre-right and right-wing parties, included the neo-fascist Italian Social Movement (MSI).
Segni attempted to strengthen Atlantic solidarity and to present Italy as Europe's most reliable ally of the United States. He also tried to represent the reassuring alternative to Fanfani's resourcefulness, advocating for Atlanticism in a season characterized by openings to the left-wing, supported by Fanfani. The most comforting signals, however, came from the economy: industry and commerce expanded, unemployment declined and Italy's GDP grew by over 6%, a rhythm that placed it among the most dynamic countries in the world. H
In social policy, various reforms in social welfare were carried out. A law of 21 March 1959 extended insurance against occupational diseases to agricultural workers, while a law approved on 17 May 1959 introduced a special additional indemnity for retired civil servants. Another important law of 4 July 1959 extended pension insurance to all artisans.
In March 1960, the Italian Liberal Party (PLI) withdrew its support to his government and Segni was forced to resign. After few months of Fernando Tambroni's government, on 26 July, Fanfani returned to the premiership, this time with an openly centre-left program supported by the PSI abstention, and Segni was appointed Minsiter of Foreign Affairs. In August 1961, Segni and Fanfani made an historic trip to Moscow, to met the Soviet leaders.
President of Italy
In May 1962, when Gronchi's term as President expired, Segni was proposed as DC's candidate by new party's leader, Aldo Moro, for the presidential election. With Segni's choice, Moro wanted to reassure the conservatives representatives of his own party, worried about a possible extreme shift on leftist stances, after the beginning of the Organic Centre-left period in February 1962. On the first two rounds, he PCI decided to vote for Umberto Terracini, while PSI supported Sandro Pertini. After the third round communists and socialists decided to converge on the candidacy of the PSDI, Giuseppe Saragat, who gained also the favor of some Christian democrat representatives.
After several ballots, on 6 May 1962, Segni was finally elected President with just the 51% of the votes, 443 votes on a total 854 electors. His election was allowed thanks to the votes of monarchist and neo-fascist representatives. It was the first time that DC's official candidate succeeded in being elected President of the Republic.
Many influent entities, notably including the Bank of Italy, the Armed Forces, Vatican hierarchies, as well as economic and financial world, were very concerned about the entry of the PSI into the government, and considered Segni a reference of stability and their most prominent political landmark. His power grew further in the aftermath of the 1963 general election, which was characterized by a loss of the DC, due to its new leftist policies. However, despite Segni's opposition, at the end of the year Moro and socialist secretary Pietro Nenni launched their first center-left government, ruling the country for more than four years.
Vajont Dam disaster
As president, Segni had to face one of the most tragic events in Italian republican history, the Vajont Dam disaster. On 9 October 1963, a landslide occurred on Monte Toc, in the province of Pordenone. The landslide caused a megatsunami in the artificial lake in which 50 million cubic metres of water overtopped the dam in a wave of 250 metres (820 ft), leading to the complete destruction of several villages and towns, and 1,917 deaths. In the previous months, the Adriatic Society of Electricity (SADE) and the Italian government, which both owned the dam, dismissed evidence and concealed reports describing the geological instability of Monte Toc on the southern side of the basin and other early warning signs reported prior to the disaster.
On the following day, Segni visited the affected areas, promising justice for the victims. However, immediately after the disaster, both the government and local authorities insisted on attributing the tragedy to an unexpected and unavoidable natural event. Despite these statements, numerous warnings, signs of danger, and negative appraisals had been disregarded in the previous months and the eventual attempt to safely control the landslide into the lake by lowering its level came when the landslide was almost imminent and was too late to prevent it. The communist newspaper l'Unità was the first to denounce the actions of management and government. The DC accused the PCI of political profiteering from the tragedy and Prime Minister Giovanni Leone promised to bring justice to the people killed in the disaster. However, a few months after the end of his premiership, he became the head of SADE's team of lawyers, who significantly reduced the amount of compensation for the survivors and ruled out payment for at least 600 victims.
1964 coalition crisis
On 25 June 1964, the government of Aldo Moro was beaten on the budget law for the Italian Ministry of Education concerning the financing of private education, and on the same day Moro resigned. President Segni, during the presidential consultations for the formation of a new cabinet, asked the socialist leader Pietro Nenni to exit from the government majority.
On 16 July, Segni sent the Carabinieri general, Giovanni De Lorenzo, to a meeting of representatives of DC, to deliver a message in case the negotiations around the formation of a new centre-left government would fail. According to some historians, De Lorenzo reported that President Segni was ready to give a subsequent mandate to the President of the Senate Cesare Merzagora, asking him of forming a "president's government", composed by all the conservative forces in the Parliament. Moro, on the other hand, managed to form another centre-left majority. During the negotiations, Nenni had accepted the downsizing of his reform programs and, on 17 July, Moro went to the Quirinal Palace, with the acceptance of the assignment and the list of ministers of his second government.
Illness and resignation
On 7 August 1964, during a meeting at the Quirinal Palace with Moro and Saragat, Segni suffered a serious cerebral hemorrhage. At the time he was 73 years old and the first prognosis was not positive. In the interim, the President of the Senate, Cesare Merzagora, served as Acting President of the Republic. Segni only partially recovered and decided to retire from office on 6 December 1964. Immediately after his resignation, Segni was appointed senator for life ex officio. On 29 December, Saragat was elected new President.
Death and legacy
During all his political career, Segni acted as a moderate conservative, staunchly opposing the "opening to the left" proposed by Fanfani and Moro, but also trying not to bring his own party too on the right-wing. He was also the first Italian president to resign from office.
The frail, often ailing Segni, was affectionately called malato di ferro, which literally means "the iron invalid". Time Magazine once quoted a friend of him: "He is like the Colosseum; he looks like a ruin but he'll be around for a long time."
During his presidency, Segni was particularly influenced by General Giovanni De Lorenzo, commander of the Carabinieri, a former partisan but with monarchical ideals. On 25 March 1964, De Lorenzo, met with Carabinieri's commanders of the divisions of Milan, Rome and Naples, proposing a plan aimed at dealing with a hypothetical situation of extreme emergency for the country, known as Piano Solo. The plan consisted of a set of measures to occupy certain institutions, such as Quirinal Palace in Rome, and essential media infrastructures, like television and radio, as well as the neutralization of communist and socialist parties, with the deportation of hundreds of left-wing politicians to a secret military base in Sardinia. The list of people to be deported also included intellectuals, such as Pier Paolo Pasolini.
On May 10, De Lorenzo presented his plan to Segni, who was particularly impressed by it. However, both journalists Giorgio Galli and Indro Montanelli believed that Segni did not really want to carry out a coup d'état, but he wanted to use the plan like a threat for political purposes.
The coup plans were revealed in 1967, when the journalists Eugenio Scalfari and Lino Jannuzzi published the plan in the Italian news magazine L'Espresso in May 1967. However, the results of the official investigation remained classified until the early 1990s. It was released by premier Giulio Andreotti to the parliamentary investigation into Operation Gladio. L'Espresso mentioned that some 20,000 Carabinieri were supposed to be deployed around the country, with more than 5,000 agents in Rome. However, Segni was never investigated for this fact.
