The Rothschild family (known as The House of Rothschild, or more simply as the Rothschilds) is a European dynasty of German Jewish origin that established European banking and finance houses from the late eighteenth century. Five lines of the Austrian branch of the family were elevated into the Austrian nobility, being given hereditary baronies of the Habsburg Empire by Emperor Francis II in 1816. The British branch of the family was elevated into the British nobility by Queen Victoria. It has been argued that during the 19th century, the family as a whole possessed by far the largest private fortune in the world, and by far the largest fortune in modern history
The Rothschilds also played a significant part in the funding of Israel's governmental infrastructure
. James A. de Rothschild financed the Knesset building as a gift to the State of Israel. and the Supreme Court of Israel building was donated to Israel by Dorothy de Rothschild. Outside the President's Chamber is displayed the letter Mrs Rothschild wrote to, the then current, Prime Minister Shimon Peres expressing her intention to donate a new building for the Supreme Court.http://en.wikipedia.org/wiki/Rothschild_family
