Boston Brahmin Russell Sturgis and Baring Brothers of London

Francis Barings owned a slave plantation, and directed The British East India Company through Francis, and even The Bank of England through Alexander.

Alexander Baring negotiated and financed The Louisiana Purchase. At the time Louisiana covered the whole of the middle of what is now the USA.

Barings financed the annexation of Texas from Mexico, and the purchase of Alaska from Russia. 

Barings financed the purchase by the United States Federal Government, i.e. Lincoln and the north, of Ironclads, which were the new military ships of their day, as well as arms!

Benjamin Moran, at the American Legation, noted with approval a speech that Baring made in the House of Commons in May 1864: The man is a gentleman…It is mortifying to me that while he is loyal to us, the only citizen of the United States belonging to his firm, Mr Russell Sturgis, is a rebel sympathizer.’ Sturgis was indeed a considerable embarrassment to his colleagues.
