The Cambon letter is a letter written on 4 June 1917 by Jules Cambon, head of the political section of the French foreign ministry, to Zionist diplomat Nahum Sokolow.
 The letter expressed French Government sympathy for Jewish colonization in Palestine.
 It is regarded as a politically essential precursor of the Balfour Declaration.
The Jewish insurgency in Mandatory Palestine involved paramilitary actions carried out by Jewish underground groups against the British forces and officials in Mandatory Palestine between 1939 and 1948.
 The tensions between Jewish militant underground organizations and the British mandatory authorities rose from 1938 and intensified with the publication of the White Paper of 1939, which outlined new government policies which placed further restrictions on Jewish immigration and land purchases and declared the intention of giving independence to Palestine, with an Arab majority, within ten years.
 Though World War II brought relative calm, the tensions again escalated into an armed struggle towards the end of the war, when it became clear that the Axis Powers were close to defeat.
 The conflict lasted until the termination of the British Mandate for Palestine and the establishment of the State of Israel in May 1948.
The Jewish People Policy Institute (JPPI; Hebrew: המכון למדיניות העם היהודי‎ ‎ ; formerly: The Jewish People Policy Planning (JPPPI)), is a Non-profit organization with the purpose of promoting and securing the Jewish people and Israel.
 The institute is a professional policy planning apparatus and a strategic thought process for the Jewish people in the most fundamental subjects concerning the Jewish people.
 The institute is served by most prominent public figures from the government, academia, the private sector in Israel and Jewish communities around the world, who constitute the think tank of this body.
The Churchill White Paper of 3 June 1922, officially Correspondence with the Palestine Arab Delegation and the Zionist Organisation was drafted at request of Sir Winston Churchill in response to the 1921 Jaffa Riots which began with intra-Jewish violence escalated into Arab attacks against Jews.
 Although the attacks were primarily facilitated by the Arabs, the British White Paper concluded that the violence was sparked by resentment towards Jewish Zionists and the perceived favoritism towards them by the British, as well as Arab fears of subjugation.
 While maintaining Britain's commitment to the Balfour declaration and its promise of a Jewish National Home in Palestine, "internationally guaranteed" and "recognized to rest upon ancient historic connection," the paper emphasized that the establishment of a Jewish National Home would not impose a Jewish nationality on the Arab inhabitants of Palestine, and "the status of all citizens of Palestine in the eyes of the law shall be Palestinian".

Mainstream Science on Intelligence was a public statement issued by a group of academic researchers in fields associated with intelligence testing that claimed to present those findings widely accepted in the expert community.
 It was originally published in the "Wall Street Journal" on December 13, 1994 as a response to what the authors viewed as the inaccurate and misleading reports made by the media regarding academic consensus on the results of intelligence research in the wake of the appearance of "The Bell Curve" by Richard Herrnstein and Charles Murray earlier the same year.
 It was drafted by professor of psychology Linda Gottfredson, sent to 131 researchers, and signed by 52 university professors specializing in intelligence and related fields, including around one third of the editorial board of the journal "Intelligence", in which it was subsequently reprinted in 1997.
 The 1997 editorial prefaced a special volume of "Intelligence" with contributions from a wide array of psychologists.
According to a public statement issued by the National Labor Federation in the late 1970s,
The Hoover Moratorium was a public statement issued by U.S. President Herbert Hoover on June 20, 1931, which he hoped would ease the coming international economic crisis, as well as provide time for recovery.
 Hoover's proposition was to put a one-year moratorium on payments of World War I and other war debt, postponing the initial payments, as well as interest.
 Many were outraged by this idea.
 This statement was met with disapproval from France, as well as many US citizens.
 Despite this negative reaction, it went on to gain support from fifteen nations by July 6.
 The moratorium was approved by Congress in December.
The Balfour Declaration was a public statement issued by the British government during World War I announcing support for the establishment of a "national home for the Jewish people" in Palestine, then an Ottoman region with a minority Jewish population.
 It read:
The Declaration of Facts was a widely distributed public statement issued by Jehovah's Witnesses during the period of persecution of the group in Nazi Germany.
 The document, which asserted the denomination's political neutrality, appealed for the right to publicly preach and claimed it was the victim of a misinformation campaign by other churches, was prepared by Watch Tower Society president Joseph F. Rutherford and released at a convention in Berlin on June 25, 1933.
 More than 2.1 million copies of the statement were distributed throughout Germany, with copies also mailed to senior government officials including German Chancellor Adolf Hitler.
 Its distribution prompted a new wave of persecution against German Witnesses.
A homeland for the Jewish people is an idea rooted in Jewish culture and religion.
 In the early 19th century, the Napoleonic Wars led to the idea of Jewish emancipation.
 This unleashed a number of religious and secular cultural streams and political philosophies among the Jews in Europe, covering everything from Marxism to Chassidism.
 Among these movements was Zionism as promoted by Theodore Herzl.
 In the late 19th century, Herzl set out his vision of a Jewish state and homeland for the Jewish people in his book "Der Judenstaat".
 Herzl was later hailed by the Zionist political parties as the founding father of the State of Israel.
 In the Balfour Declaration of 1917, the United Kingdom became the first world power to endorse the establishment in Palestine of a "national home for the Jewish people."
 The British government confirmed this commitment by accepting the British Mandate for Palestine in 1922 (along with their colonial control of the Pirate Coast, Southern Coast of Persia, Iraq and from 1922 a separate area called Transjordan, all of the Middle-Eastern territory except the French territory).
 The European powers mandated the creation of a Jewish homeland at the San Remo conference of 19–26 April 1920.
 In 1948, the State of Israel was established.
