Lateran Treaty
Negotiations for the settlement of the Roman Question began in 1926 between the government of Italy and the Holy See, and culminated in the agreements of the Lateran Pacts, signed—the Treaty says—for King Victor Emmanuel III of Italy by Benito Mussolini, Prime Minister and Head of Government, and for Pope Pius XI by Pietro Gasparri, Cardinal Secretary of State, on 11 February 1929. It was ratified on 7 June 1929. The agreements were signed in the Lateran Palace, hence the name by which they are known.
Locarno Treaties
The Locarno Treaties were seven agreements negotiated at Locarno, Switzerland, on 5–16 October 1925 and formally signed in London on 1 December, in which the First World War Western European Allied powers and the new states of Central and Eastern Europe sought to secure the post-war territorial settlement, and return normalizing relations with defeated Germany (the Weimar Republic). It also stated that Germany would never go to war with the other countries. Locarno divided borders in Europe into two categories: western, which were guaranteed by Locarno treaties, and eastern borders of Germany with Poland, which were open for revision.
