61. Louis XIV, par exemple: ROI. His dad was XIII. Became the King of France at the ripe old age of four years and eight months when his dad died in 1643. Reigned for 72 years. Then his grandson XV took the reign. XV arranged the marriage of his grandson XVI to Marie Antoinette. XVI took over in 1774, and was to become the last ROI of France.
XIV established absolute monarchical rule in France, appeased the nobles, consolidated powers, started a lot of wars, signed a lot of treaties, increased France's turf in Europe, and improved France's standing in the world power rankings. He had his architects and builders rehab his dad's hunting lodge and turned it into the Palace of Versailles.
France seemed to get a pretty good R.O.I. on XIV as ROI. But over the course of about 150 years of absolute monarchical rule, things weren't going so well for the people of France, perhaps especially under the rule of his successors. It all culminated in the French Revolution, the ending of the monarchy, the beheading of XVI and Marie in 1793, and the rise to power of Napoleon Bonaparte.
Enough of that. On to the grid !
