Following the outbreak of the 1917 Russian Revolution, Skossyreff was able to seek political asylum in England, where he enlisted in the British army for the end of World War I.

He moved to the Netherlands in the mid-1920s, where he was in a list of Prominent Foreign Revolutionaries in 1924, prepared by the General Intelligence and Security Service, in which he was noted as an international swindler.

Through his visits to Andorra, a co-Principality in the Pyrenees co-princed by the Bishop of Urgell and President of France, in the early 1930s, Skossyreff worked on gaining power.

Through falsely portraying himself as a member of the European aristocracy, Skossyreff proposed freedoms, modernisation, foreign investments and the recognition of a tax haven to Andorra through his self-published constitution.

When the Russian Revolution of 1917 broke out, he was able to seek political asylum in England, where he enlisted for around two years in the British Army for the end of World War I.

[21] On the 17 May 1934, Skossyreff presented the former court prosecutor and other advisers to the Council of the Valleys (former name of the Government of Andorra) a document laden with his suggestions, in which he justified his intentions of rule.

[23] Skossyreff saw himself as "exiled" and settled in La Seu d'Urgell (just 5 km; 3 miles from Andorra) in the Hotel Mundial,[24][25] where he began behaving like an authentic monarch; one which led to many interviews, some of them telephone calls, including those given to the newspapers The Times and The Daily Herald.

In Perpignan, he managed to have his plans reach the representative of Prince Jean d'Orleáns, Duke of Guise, and pretender to the throne of France.

[28] During his "exile", Skossyreff granted visits, made official receptions and organised numerous events, such as a mass for the late Catalan president Francesc Macià.

The Co-principality would have freedoms, modernisation, foreign investments and the recognition of a tax haven; one which was argued would bring Andorra into the modern age.

Skossyreff proposed to make Andorra one of the most important business centers in the world, where banks, financial entities and international companies would not waste time installing their social domicile there, taking advantage of the tax regime.

[46][47] Historian Arnau González explained that during his stay at Modelo de Madrid, Boris and his collaborators continued to interpret the papers they had signed.

Skossyreff was later said to have called Francisco Fernandes Lopes in distress with a plea to contact the then Portuguese dictator - Oliveira Salazar - to have him diplomatically intercede for him; one which seems to have occurred.

[60] In February 1939, Skossyreff was in a French prison camp with Spanish anti-Francoists, alongside Italian and Central European anti-fascists from the regions occupied by the Third Reich before World War II.

[58] He took up residence in Boppard (West Germany); however, he went to an area controlled by the Soviets, leading to his arrest and sentencing to 25 years of forced labor in a Siberian camp.
