Plenipotentiary in the context of "Mamoru Shigemitsu"

The 1921 Anglo-Irish Treaty (Irish: An Conradh Angla-Éireannach), commonly known in Ireland as The Treaty and officially the Articles of Agreement for a Treaty Between Great Britain and Ireland, was an agreement between the government of the United Kingdom of Great Britain and Ireland and the government of the Irish Republic that concluded the Irish War of Independence. It provided for the establishment of the Irish Free State within a year as a self-governing dominion within the "community of nations known as the British Empire", a status "the same as that of the Dominion of Canada". It also provided Northern Ireland, which had been created by the Government of Ireland Act 1920, an option to opt out of the Irish Free State (Article 12), which was exercised by the Parliament of Northern Ireland.

The agreement was signed in London on 6 December 1921, by representatives of the British government (which included Prime Minister David Lloyd George, who was head of the British delegates, and Winston Churchill, who was Secretary of State for the Colonies) and by representatives of the government of the Irish Republic (which included Michael Collins, who was Secretary of State for Finance, and Arthur Griffith, who was Secretary of State for Foreign Affairs). The Irish representatives had plenipotentiary status (negotiators empowered to sign a treaty without reference back to their superiors) acting on behalf of the Irish Republic, though the British government declined to recognise that status. As required by its terms, the agreement was approved by "a meeting" of the members elected to sit in the House of Commons of Southern Ireland and [separately] by the British Parliament. In reality, Dáil Éireann (the legislative assembly for the de facto Irish Republic) first debated then approved the treaty; members then went ahead with the "meeting". Though the treaty was narrowly approved, the split led to the Irish Civil War, which was won by the pro-treaty side.

The Sino-Japanese Friendship and Trade Treaty was the first treaty between Japan and the Qing dynasty. It was signed on 13 September 1871 in Tientsin by Date Munenari and Plenipotentiary Li Hongzhang.

The treaty guaranteed the judiciary rights of Consuls, and fixed trade tariffs between the two countries.

The Far Eastern Bureau of the Communist International was an organ of the Communist International (Comintern) established in 1920 to develop their political influence in the Far East. The name was used in subsequent years, but the continuity of the organization cannot be proven.

The organization was originally founded as the Far Eastern Bureau of the Russian Communist Party, when the central committee of that organization sent Vladimir Vilensky-Sibiryakov to Siberia as plenipotentiary for Far Eastern Affairs. Grigori Voitinsky was sent to the Republic of China in 1920, where he undertook the preparatory work for the formation of the Chinese Communist Party (CCP). In June 1921, Vladimir Neumann and Henk Sneevliet arrived in Shanghai and urged Li Da to convene a national-level meeting to form a communist party, which Li did. Both Comintern representatives attended the CCP's founding meeting in July 1921.

The president of Albania, officially the president of the Republic of Albania, is the head of state, commander-in-chief of the military and the representative of the unity of the Albanian people.

The president sets the date of elections and referendums, grants pardons and awards, grants citizenship and permits it to be given up, accepts the credentials of diplomats serving in Albania, appoints plenipotentiary representatives and the director of the State Intelligence Service at the proposal of the prime minister, and officially promulgates all laws passed by the Albanian parliament or by referendum. The Office of the President consists of the immediate staff of the president as well as support staff reporting to the president. The office is seated in the Presidential Office in the capital city Tirana. The spouse of the president is recognized as the first lady of Albania, but holds no official role in the presidency. She often plays a protocol role at the Presidential Palace and during official visits.

The Kingdom of Iceland (Icelandic: Konungsríkið Ísland; Danish: Kongeriget Island) was a sovereign and independent country under a constitutional and hereditary monarchy that was established by the Act of Union with Denmark signed on 1 December 1918. It lasted until 17 June 1944 when a national referendum established the republic of Iceland in its place.

Under a personal union, due to the Act of Union, the monarch was simultaneously monarch of Denmark. The Parliament of Iceland asked that Denmark represent Iceland internationally, and day-to-day matters were delegated to a Danish plenipotentiary for Icelandic affairs based in Reykjavík, and – after the German invasion of Denmark in 1940 – a regent was appointed.

An apostolic nuncio (Latin: nuntius apostolicus; also known as a papal nuncio or simply as a nuncio) is an ecclesiastical diplomat, serving as an envoy or a permanent diplomatic representative of the Holy See to a state or to an international organization. A nuncio is appointed by and represents the Holy See, and is the head of the diplomatic mission, called an apostolic nunciature, which is the equivalent of an embassy. The Holy See is legally distinct from the Vatican City or the Catholic Church. In modern times, a nuncio is usually an Archbishop.

An apostolic nuncio is generally equivalent in rank to that of ambassador extraordinary and plenipotentiary, although in Catholic countries the nuncio often ranks above ambassadors in diplomatic protocol. A nuncio performs the same functions as an ambassador and has the same diplomatic privileges. Under the 1961 Vienna Convention on Diplomatic Relations, to which the Holy See is a party, a nuncio is an ambassador like those from any other country. The Vienna Convention allows the host state to grant seniority of precedence to the nuncio over others of ambassadorial rank accredited to the same country, and may grant the deanship of that country's diplomatic corps to the nuncio regardless of seniority. The representative of the Holy See in some situations is called a Delegate or, in the case of the United Nations, Permanent Observer. In the Holy See hierarchy, these usually rank equally to a nuncio, but they do not have formal diplomatic status, though in some countries they have some diplomatic privileges.

Nazi Germany undertook several research programs relating to nuclear technology, including nuclear weapons and nuclear reactors, before and during World War II. These were variously called Uranverein (Uranium Society) or Uranprojekt (Uranium Project). The first effort started in April 1939, just months after the discovery of nuclear fission in Berlin in December 1938, but ended shortly ahead of the September 1939 German invasion of Poland, for which many German physicists were drafted into the Wehrmacht. A second effort under the administrative purview of the Wehrmacht's Heereswaffenamt began on September 1, 1939, the day of the invasion of Poland. The program eventually expanded into three main efforts: Uranmaschine (nuclear reactor) development, uranium and heavy water production, and uranium isotope separation. Eventually, the German military determined that nuclear fission would not contribute significantly to the war, and in January 1942 the Heereswaffenamt turned the program over to the Reich Research Council (Reichsforschungsrat) while continuing to fund the activity.

The program was split up among nine major institutes where the directors dominated research and set their own objectives. Subsequently, the number of scientists working on applied nuclear fission began to diminish as many researchers applied their talents to more pressing wartime demands. The most influential people in the Uranverein included Kurt Diebner, Abraham Esau, Walther Gerlach, and Erich Schumann. Schumann was one of the most powerful and influential physicists in Germany. Diebner, throughout the life of the nuclear weapon project, had more control over nuclear fission research than did Walther Bothe, Klaus Clusius, Otto Hahn, Paul Harteck, or Werner Heisenberg. Esau was appointed as Reichsmarschall Hermann Göring's plenipotentiary for nuclear physics research in December 1942, and was succeeded by Walther Gerlach after he resigned in December 1943.
