In the 19th and 20th centuries, an imaginary state was set up on this island by the Bertoleoni family as the Kingdom of Tavolara. After Italian unification, King Paolo actively sought recognition from Italy. During his reign, in 1868 the Italian government began operating a lighthouse on the northeast end of the island. After Paolo's death in 1886, he was succeeded by his son, Carlo I. In 1900. Carlo was succeeded upon his death in 1928 by his son King Paolo II. Paolo went abroad, however, and left Carlo's sister Mariangela as regent in his absence. Mariangela died in 1934, leaving the kingdom to Italy. Her nephew Paolo II still claimed the kingdom, however, until his death in 1962. That year marked the installation of the NATO station. The present claimant is an Italian citizen named Tonino Bertoleoni, who runs "Da Tonino," a restaurant on the island. Politically, the interests of the island are represented in its external dealings by Prince Ernesto Geremia di Tavolara, of La Spezia, Italy, who has written a history of the island.
