Across nearly 1000 years of royal history, there have been many famous royals who have played a key role in growing the family's popularity and influence.
While Queen Victoria would certainly top this list as a key player thanks to her determination to have her children and grandchildren marry into European royal families, there is another royal who should be commended for his efforts. Lord Louis Mountbatten was born as Prince Louis of Battenberg and was a grandson of Queen Victoria. He is widely credited as being a 'secret weapon' for the Royal Family and served as a mentor for his godson, King Charles III.
