I wanted to do this House of Bernadotte 3 part series including other Scandinavian royal families Norway and Denmark. But I decided that in the other Royal Household we will have a glimpse of marriage between a few Bernadotte descendants and other royals.

Norway:
Although Norway's current monarch is a member of the House of Gluckbourg or also known as the House of Shleswig-Holstein-Sonderburg-Gluckbourg a subdivision on the House of Oldenburg.

Whilst in 1818 Norway was still a member of the Swedish realm, Bernadotte also known as King Charles IV John of Sweden also ruled over Norway as King Charles III John of Norway. How this came about you may ask well lets get down to history.

King Charles IV John(Karl Johan) was a huge part of the Treaty of Kiel which allow Sweden and Norway to be one due to Denmark lose to the Napoleonic wars and ceding away Norway. Mind you Norway didn't allow itself to be a part of Sweden but pressure from Karl Johan had it give away he later on invaded and suppressed Norwegian Army Force. Unlike when they were with Denmark, Norway and Sweden had to be ruled by one king under the Convention of Moss but by participating as its own with a different institutions.

Karl Johan was actually Crown Prince to both kingdoms and only became King after the passing away of King Carl XIII. Karl Johan was then crown king in both Norway on September 7 1818. First coronation being held in over three centuries. He began a tradition which still remains till date, during his coronation, Karl Johan was crown in his Marshal military wear. Since then future Norwegian Kings after him did the same including present King Harald.

Reign:
During his reign in Norway Karl Johan was actually never popular amongs the people, Firstly for his implication in 1818, and his actions to change the Constitution giving more power to the Royal King. According to the Constitution in dating back to many years before, the parliament also known as The Sorting giving them more power which had not be seen in any European countries.
