Do you think Merry del val could finally solve the Roman question? he is 55 years old when he becomes pope in 1918, which would give him a fairly long papacy, depending on his stance, and that of the Italian government, both sides can come to a similar deal with the lateran treaty or the pope can consider a prisoner in the vatican to this day
I think some sort of agreement will be concluded: the Church had began to tone down their opposition in the early 20th Century, when Pope Pious X “suspended” the Non Expedit, an edict proihibiting Catholics to vote in Italian elections, under the so called Gentiloni Pact with the Giovanni Giolitti’s Liberal Party. Even conservatives were becoming more open to the idea itself, fearful of the growing socialist vote. IOTL Giolitti was frontrunner to return to the premiership in 1914 when Salandra resigned but was sidelined after the King decided to move Italy closer to the war and signed the London Treaty (Giolitti was a strong neutralist). ITTL I can see him returning as Prime Minister and dominating the political scene until his death in 1928. Given his qualities as statesman (and de Val’s diplomatic abilities) I can see them signing an agreement to close the Roman Question.

One of the things that prevented the onset of racial violence and possible civil warin the 1950s/ 1960s in the Americas was the presence of the League of Nations peacekeeping forces. As a result of an appeal by Malcolm Little and A. Philip Randolph in 1957, African-Americans called for the protection of African-Americans from lynching below the Mason-Dixon line. For many white Southerners, this period, lasting until 1968, was dubbed "The Great Surrender", which led to the rise of Neo-Confederate sentiments, and is often cited as the cause for the second rise of the Ku Klux Klan. League monetary script, used to pay peacekeeping forces was often refused by white local residents, often leading to further violence. The states of Alabama, Mississippi, Florida, Arizona and Texas became known as the "Hard Five" proclaiming in 1964, "Segregation Now, Segregation Forever"...

Portrait of King Ernest Augustus III of Hanover after the restoration of the kingdom in 1924, he reigned until his death in 1953
The Kingdom of Hanover was defeated and annexed by Prussia after the Austro-Prussian War in 1866. Since then, the German-Hanoverian Party has consistently defended the rebirth of the Kingdom of Hanover and confiscated the assets returned to the Kingdom's ruling house. In 1913, the marriage of Ernest Augustus of the House of Hanover to Princess Victoria Louise of Prussia, daughter of William II, helped to cure much of the bad blood between the houses of Hanover and Hohenzollern. During the late 1910s, the German-Hanoverian Party again pressed for a local referendum to determine whether Hanover should be restored.

Seeing this as an opportunity to rectify an injustice and weaken Prussia's hold, the anti-Prussian coalition of German nobles and government officials began pressing for a yes vote in the referendum. Ebert and the Social Democrats opposed the referendum because they feared it would generate more social unrest while the German People's Party supported the integrity of the Prussian state. The Center Party, the main conservative party but dominated by Roman Catholics and nominally opposed to Prussia's rule in Germany, pressed for the referendum to take effect. William II, although favorable to his son-in-law and family, was privately opposed to allowing the referendum. When the Center-DVP coalition took power from the Social Democrats in 1923,

The referendum took place in 1924. With substantial support from the anti-Prussian coalition, the German-Hanoverian Party was energized and campaigned constantly. In the official election results, the yes vote gained a small majority and turnout was sufficient to decree devolution at 34.5 percent, just above the one-third turnout requirement. The German government and all parties recognized and respected the result. The Kingdom of Hanover was restored in late 1924 and Prince Ernest Augustus, the head of the House of Hanover, assumed the throne as Ernest Augustus III.
However, the successful referendum split the ruling coalition. The Center Party was split between pro-Prussian and anti-Prussian conservatives, while the German People's Party split from the coalition government. With the support of disaffected MPs from the Center the DVP was able to secure the minority government.
On the subject of a world without world wars, one thing that would definitely be different would be the world's population. It would be significantly larger in some areas, smaller in others without a post-war baby boom. Many would be born who otherwise wouldn't have been, likewise many others would not have been born due to their parents not having met during wartime. Then there are those whose lives were changed by their service, would their lives have been better, or worse?
How about the German American and Will they make U.S allied the German Empire since they Largest ancestry in America in this world

Pope Gregory XVII (Latin: Gregorius XVII, Italian: Gregorio XVII) (10 October 1865 – 29 January 1937) Born Rafael Merry del Val, was head of the Catholic Church from 1918 until his death in 1937. He succeeded Nicholas VI and was succeeded by Pius XI

Gregory XVII issued numerous encyclicals, including Quadragesimo anno (With help from Cardinal Achille Ratti) on the 40th anniversary of Pope Leo XIII's groundbreaking social encyclical Rerum novarum, highlighting the capitalist greed of international finance, the dangers of socialism and issues of social justice, and Quas cousins, establishing the feast of Christ the King in response to anticlericalism. The encyclical Studiorum ducem, promulgated on June 29, 1923, was written on the occasion of the VI centenary of the canonization of Thomas Aquinas, whose thought is hailed as central to Catholic philosophy and theology. The encyclical also highlights the Pontifical University of St. Angelicum, where Thomas may be said to dwell).

During his eighteen-year pontificate, the long-standing hostility with the Italian government over the status of the papacy and the Church in Italy was successfully resolved in the 1932 Treaty of Rome through an agreement with the Italian government that created the Papal State in leonine city, the end of his papacy was also marked by the Financial Crisis of 1932, where he called on Catholics from all over the world to help people suffering from the crisis (mainly in the United States), his papacy also saw the initial phase of the decade of the ten wars, where he was a staunch defender of peace, during the Spanish civil war however he called on Catholics to protect Spain from what he called the "Veiled Socialism" that republican rebels intended to implement in Spain

Gregorius XVII died on 29 January 1937 in the Apostolic Palace and is buried in the Papal Grotto of St. Peter's Basilica. In the course of excavating the space for his tomb, two levels of cemeteries were discovered that revealed bones now venerated as the bones of Saint Peter.
