Here are some one liners...
The Virgin Queen Takes the Reins of England -- Queen Mary dies of the flu and Queen Elizabeth takes her place. It is the beginning of a golden age for England.
The Livonian War and Ivan the Terrible -- Ivan is just being terrible but with a good reason. It seems a lot like World War I though.
The University of Jena is Established -- I may be silly here but I mention this because of a favorite book of mine by Eric Flint entitled "1632". The University of Jena figures in it prominently.
