The following is an excellent educational tool.  The Rothschilds didn't suddenly become stupid or lose their money, they simply purchased the news media and with it anonymity which is the truest measure of wealth and power:


As Count Egon Caesar Corti wrote in the forward to his The Rise of the House of Rothschild,

"Historians, in interpreting the 19th century, have laid stress on many and various aspects of the period under study; and descriptions of isolated periods, single episodes, and individuals are scattered amongst hundreds and even thousands of books. On the other hand, certain special features of the period under consideration have been, for various reasons, entirely neglected.

An example of such neglect is the ignoring by historians of the role played by the Rothschild family in the history of the 19th century, and the object of this work is to appraise the important influence of this family on the politics of the period, not only in Europe but throughout the world. For, strangely enough, the influence of the Rothschilds is barely mentioned, or at the most casually referred to, in otherwise comprehensive and painstaking historical treatises.
Special literature dealing with the House of Rothschild usually falls into one of two groups, either fulsome paeans of praise commissioned by the House itself, or scurrilous pamphlets inspired by hatred—both equally unpleasant...

The object of the present work, which deals with the period 1770-1830, is to trace the rise of the House of Rothschild from its small beginnings to the great position it attained, culminating in the year of its great crisis.

In the course of my researches I found that references to the name of Rothschild in official docuмents and in books of memoirs were as common as they are rare in contemporary textbooks. I made a point of collecting all available data until my drawers were literally crammed with letters, deeds, and docuмents containing the name of Rothschild, and bearing dates of almost every year of the nineteenth century. My next step was to visit the various European capitals which had been the scene of the family activities, in order to enrich my store of references with all the relevant literature. The subject is in- deed inexhaustible, but the material I had amassed encouraged me to essay a complete picture.

The subject required the most delicate treatment, but my determination to undertake the work was accompanied by the definite intention of according it complete impartiality, for I was convinced from the beginning that a prejudiced outlook would render the work utterly valueless.

The House of Rothschild, as will be readily understood, did not throw open its archives to my inspection, for it is particularly careful in guarding its more important business secrets. But this was not entirely without its advantage, for it left me completely free from political considerations and uninfluenced by racial, national, and religious predilections or antipathies. I was thus enabled, in accordance with my wish, to begin an independent historical research into the part played by this House in the nineteenth century, which I knew to be far more important than is commonly thought.

The general scheme of this work will be built upon facts alone, in a practical way such as will help us to form our own judgment on individuals and the part they played in world events...

The material was collected for over a period of three and a half years, and only after much care has been spent on it do I now offer it to the public. It is submitted in the hope that it will be judged in accordance with its intentions. It is inspired by an intense love of truth, and it relates the story of an unseen but infinitely powerful driving force which permeated the whole of the 19th century.

Corti's second work, The Reign of the House of Rothschild, is well worth acquiring also.
