According to what I've read on Friedrich Christian of Saxony, it seems a crying shame that he only served as ruler for less than three months. I'm not saying his wife/brother didn't do as well as regent for his son, but his death led to the installation of a Russian "puppet" on the throne of Poland, and eventually the partitions of that country. I've been wondering about the repercussions in both Saxony and Poland if he had lived. All his brothers (with the exception of the duke of Courland) lived until the 19th century, but Friedrich DID have health problems, so maybe he only lives around 10-15years longer. How might this shake things up?
