The Kingdom of Andorra was established in 1934 when the Russian adventurer Boris Skossyreff visited the country and declared himself its ruler. After waging a brief "non-war" with the Bishop of Urgel (in Spain), an arrangement was made with both the Spanish and French authorities. There was an influx of persons who had left Russia for various reasons - some of whom were quickly expelled because of their revolutionary and other tendencies. Others, however, contributed to the economic development of the country into the prosperous country it is today.
