The Negotiations for the Lateran Treaty
The Historical Context:
To understand the significance of the Lateran Treaty, let’s review the complex historical backdrop against which it unfolded. The unification of Italy in 1871 resulted in the annexation of the Papal States, which had been under the control of the Pope for centuries, into the newly formed Kingdom of Italy. This pivotal event stripped the Pope of both his temporal authority and the Papal States, creating a deep and enduring source of tension between the Vatican and the Italian state.
Pope Pius IX, who had declared himself a "prisoner of the Vatican," and his successors, Pope Leo XIII and Pope Pius X, maintained a policy of "non possumus," a declaration that they could not and would not accept the Italian government. This principled stand led to the self-imposed exile of Popes from Rome, further complicating relations between the Holy See and the Italian state. Yet, as the years rolled on, the need for reconciliation became apparent.
The Main Players:
The negotiations for the Lateran Treaty were shaped by a diverse group of key players, each with their own motivations and contributions to the process.
Pope Pius XI (Achille Ratti)
At the helm of the Roman Catholic Church during these negotiations was Pope Pius XI. Elected as Pope in 1922, he was determined to resolve the Roman Question, re-establish diplomatic relations with Italy, and secure the rights and independence of the Vatican.
Benito Mussolini
Italy's authoritarian and fascist leader, Benito Mussolini, was a pivotal figure in these negotiations. His motivations were multifaceted. Mussolini aimed to gain international recognition for his regime, which had faced opposition on various fronts. Additionally, he sought the support of the Catholic Church to legitimize his rule and eliminate domestic opposition, particularly from Catholic political groups within Italy.
Pietro Gasparri
Cardinal Pietro Gasparri, the Vatican's chief negotiator, played a crucial role in these complex negotiations. Possessing extensive experience in international diplomacy, Gasparri's diplomatic finesse and unwavering commitment to the Holy See's interests were pivotal.
Count Dino Grandi
Count Dino Grandi, an Italian diplomat, and a close confidant of Mussolini, served as the primary Italian negotiator. His diplomatic skills and deep ties to the fascist regime made him a central figure in the negotiations.
Cardinal Eugenio Pacelli
Before ascending to the papacy as Pope Pius XII, Cardinal Eugenio Pacelli played a pivotal role as a close advisor to Pope Pius XI during the negotiations. His later papacy marked a significant era in the relationship between the Vatican and the wider world.

What All Sides Wanted:
Like all negotiations, understanding the motivations and objectives of each side is crucial to success. It was a delicate dance, and the stakes could not have been higher.
The Vatican
The Holy See had several key objectives in these negotiations. Foremost, they sought the recognition of their independence and sovereignty over Vatican City. In addition, the Vatican aimed to secure the restoration of the Pope's temporal power, viewing the loss of the Papal States in 1870 as an unlawful act. Furthermore, they aspired to maintain the position of the Catholic Church as the official state religion in Italy and safeguard the rights of the Church within the country.
Italy and Mussolini
For Benito Mussolini's regime, international recognition was a primary goal. In addition, resolving the long-standing Roman Question was crucial, as it had hindered Italy's relations with the Vatican.
The Complexity of Negotiations:
The negotiations leading to the Lateran Treaty were characterized by extraordinary complexity, rooted in deeply entrenched historical grievances and the intricate political landscape of the time.
Vatican's Non Possumus Policy
The Vatican's steadfast refusal to accept the legitimacy of the Italian state added a layer of complexity to the negotiations. The Holy See's enduring "non possumus" stance, in place for nearly six decades, required delicate handling.
Fascist Regime and Totalitarianism
The rise of fascism and Mussolini's authoritarian regime in Italy introduced significant challenges. The Vatican had to carefully navigate its relationship with a government typified by totalitarian tendencies, while remaining true to its principles and values.
International Diplomacy
The negotiations transcended Vatican-Italian relations, involving international dimensions. Foreign governments, particularly the United Kingdom, with its vested interests in the Mediterranean, played a role in facilitating the negotiations and encouraging the parties to reach an agreement.
Legal and Territorial Complexities
The intricacies of determining the borders of Vatican City and addressing the issue of extraterritoriality posed technical challenges. Additionally, the treaty had to address the matter of compensation for the Vatican's loss of the Papal States.
The Negotiation Process:
The negotiations leading to the Lateran Treaty commenced in earnest in the early 1920s and spanned several years. The process can be broken down in the following stages:
Initial Talks
The initial negotiations took place in utmost secrecy, with preliminary discussions conducted discreetly behind closed doors. The Vatican's negotiators, Cardinal Gasparri, and Eugenio Pacelli, knew that direct and public negotiations could create more obstacles, given the delicate political climate in Italy. As a result, they adopted a discreet approach, relying on quiet diplomacy and backchannels.
To maintain secrecy and confidentiality, both sides used trusted intermediaries to carry messages between the Vatican and the Italian government.
Cardinal Gasparri, an experienced diplomat, and Count Grandi, Mussolini's trusted aide, played pivotal roles during this initial phase.
Drafting the Treaty
Cardinal Gasparri and Count Grandi assumed the critical responsibility of drafting the terms of the treaty. Their discussions encompassed issues such as the recognition of the Vatican's territorial sovereignty, compensation for the loss of the Papal States, and the Church's privileges within Italy.
Papal Decisions
Pope Pius XI himself was directly involved in significant decisions throughout the process. His flexibility and willingness to find common ground were key factors in steering the negotiations towards a successful resolution, while ensuring the protection of the Church's interests.
The Final Agreement:
After years of secretive negotiations and numerous drafts, the Lateran Treaty was officially signed on February 11, 1929, by Cardinal Gasparri on behalf of the Vatican and Count Grandi representing Italy. The treaty consisted of three separate agreements:
The Lateran Treaty
This agreement formally recognized Vatican City as an independent and sovereign state, marking the end of the territorial dispute over the Papal States. The treaty also established the Vatican's full sovereignty over its territory.
The Concordat
The Concordat was a bilateral agreement between the Holy See and the Italian government, addressing the relationship between the Catholic Church and the state. It granted the Church special privileges, including rights related to religious education and marriage.
The Financial Convention
This component outlined the financial compensation provided to the Holy See for the loss of the Papal States. The Vatican received a substantial sum as compensation for past grievances.
Conclusion:
The Lateran Treaty stands as a turning point in the history of the Roman Catholic Church and the relationship between the Vatican and the Italian state. The contributions of key players, including Pope Pius XI, Cardinal Gasparri, Count Grandi, and Cardinal Pacelli, were integral in reaching an agreement that addressed the interests of all parties. Reflecting on this historic event, we are reminded of the transformative power of diplomacy, compromise, and the pursuit of peace. The Lateran Treaty endures as a testament to the possibility of resolving seemingly insurmountable disputes through dialogue and negotiation, a lesson that continues to resonate in the annals of history.
