I just read that link on Henry VII and bonds, pretty interesting, thank you. Just one question, the article mentioned that Henry recieved money for knighting his son, could you please elaborate on this occurrence?

So this is an example of Henry VII looking back into the statute books to find old rights or powers that hadn’t been invoked in a while – in part because earlier kings had abused the hell out of them and in the process helped to provoke the Barons’ Revolt and the Magna Carta – and then using the hell out of them.

In this case, Henry VII was invoking the right of feudal aid. Feudal aid was a special one-time payment to be made to one’s liege lord on special occasions: when the oldest son became a knight, when the eldest daughter was to be married, when the lord was going on crusade or needed to be ransomed, etc. 

Henry VII missed few tricks, so not only did he invoke feudal aid when he knighted his eldest son Arthur, but when Arthur died and Henry became his new eldest son,  he did it again, and then again when he married his daughter to the King of Scotland. And each time, he raised the equivalent of at least £11-20 million pounds in today’s money.
