Inspired by me watching BBC's The Musketeers:
Anne of Austria was pregnant four (possibly more) times before she gave birth to Louis XIV Dieudonné in 1638.
But say one of her prior pregnancies goes sideways and the miscarriage/labor kills her (childbed often did, so I don't think this is unreasonable).
This means there are four possible PODs (1619, 1622, 1626 and 1631) and obviously the geopolitical landscape would be different for each. Obviously if the child survives will affect who Louis XIII will remarry to, as well.
So, considering that Richelieu was LXIII's brain a lot of the time, and a marriage would be arranged to advantage France, who might be considered in the aforementioned years?
Please discuss.
