Hoover Moratorium: 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 Songs of the Jewish Shtetle: The Songs of the Jewish Shtetle is a cultural musical project aimed at preserving the Jewish cultural heritage.  The project has gathered songs in Yiddish, a language put on the Red List of Threatened Languages by UNESCO.  Before World War II the number of native Yiddish speakers amounted to 11 million people.  During Holocaust 6 million Jewish people were killed, thus the number of Yiddish speakers halved.  The language continued in literature, oral speech, Ashkenazi folklore, and in songs.  These songs reflect habits and ways, language and music, the soul of the Jewish people.  The attitude to parents, children, neighbours, religion, work, native home, the world around and themselves, to life and death – all this is expressed in the art of singing, and each of the Songs of Jewish Shtetle becomes a little music play.  The project is unique as the Jewish songs in Yiddish, which had been persecuted for centuries, the songs that had only been played by small klezmer ensembles before, were for the first time performed with all the vivacity of a big symphony orchestra.

Homeland for the Jewish people: 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.
