Fascinating and an abuse of history by omitting the Templars, who invented the check book and banking as we know and the moral bankruptcy of the Catholic Church under edict from Pope Clement IV and that Hobbit Philip IV king of France both of whom were in debt to not only to the Templars but, many other nations and prominent peoples of then europe.
I think that the Templars were omitted because they did not make their money through ordinary business and banking transactions in Europe and left no clear successors. In contrast, Jakob Fugger did just that, to his immense benefit and helping his progeny, his customers, and commerce in Europe to prosper.
[snip] Temple Church is not just an important architectural, historical and religious site. It is also London’s first bank... A pilgrim could leave his cash at Temple Church in London, and withdraw it in Jerusalem. Instead of carrying money, he would carry a letter of credit. The Knights Templar were the Western Union of the crusades. We don’t actually know how the Templars made this system work and protected themselves against fraud. Was there a secret code verifying the document and the traveller’s identity? [/snip]
