Ο Oscar B (Oscar II, 1829-1907), born 21 January 1829, was the third son of Oscar I and Queen Josephine. He ascended to the throne of Sweden and Norway in 1872, succeeding his brother Charles XI. He was educated and erudite, with interests ranging from literature and poetry to science. Oscar II was an ardent supporter of cultural and scientific progress, as well as international diplomacy.

His reign was marked by reforms, but also by challenges, such as the dissolution of the Union with Norway in 1905. Although the loss of Norway was a blow, Oscar II remained a respected figure, leaving a strong legacy for Sweden.

Oscar II was an active member of Freemasonry and continued the tradition of his family. He was initiated in 1853 into the Lodge Royal Lodge of Stockholm (Kungliga Stora Logen), which was considered one of the most prominent lodges in Sweden.

He served as Grand Master of the Swedish Press (Svenska Frimurare Orden), ranking the highest in the institution. As Grand Master he held the 10th rank, a title combining leadership and philanthropy.

His contribution to Swedish Freemasonry focused on the preservation of moral and spiritual values, and he supported the charitable activities of the Lodge.

During his reign, Freemasonry flourished in Sweden, with a particular emphasis on moral, philosophical and charitable activities. He actively supported Masonic philanthropy, especially in the field of education and social welfare.

Oscar II’s Masonic activities reflect his general commitment to the moral and cultural progress of his nation, harmonizing Freemasonry with his vision of a harmonious and enlightened society. His influence cemented the strong ties between the Swedish kingdom and the Masonic Brotherhood, leaving a lasting legacy in both spheres.

Oscar II died on 8 December 1907 in Stockholm, leaving behind a powerful legacy as a patron of art, science and morality.
