County of Ligny (Merveilles du Monde Map Game)

Background
John II, Count of Auvergne and Boulogne, passes away from life and Joan II, David III's wife inherits the Duchy of Auvergne and the County of Boulogne, thus the Scottish Crown Prince David III effectively rules over his wife's domain via jure uxoris rule.

In 1408, King Robert II Bruce of Scotland abdicates the Scottish throne to his son, Crown Prince David III.

The personal union between the Duchy of Auvergne, the County of Boulogne and the Kingdom of Scotland begins.
