Here is a blog post from 2011 going through the Rothschild dynasty from their beginning in the 18th century to current time (pay special attention to the beginning when they are alleged satanists): http://humansarefree.com/2011/09/history-of-house-of-rothschild-complete.html?m=0

A great documentary by Bill Still, explaining how the world's economy used to be, and how it is now. Explaining its problems, and how the Rothschilds control everything can be seen here (highly recommended): The Secret of Oz by Bill Still

The question is, can we confirm this information somehow? A blog post and a documentary merely saying things is hardly proof.

Edit 1: Here is a list of banks that numerous people claim are all controlled by the Rothschilds, but evidence is lacking: http://humansarefree.com/2013/11/complete-list-of-banks-ownedcontrolled.html
