三帝同盟
Saburov was born on the estate of Veryaevo in the district of Elatma in the Government of Taboff. His brother Andrei held for several years the portfolio of the Minister of Public Instruction. Petr Alexandrovich graduated from the Tsarskoye Selo Lyceum, in 1854, gaining a first gold medal. After employment in the Chancellery (1857–59), he worked in Munich, and then in England, where he stayed for eleven years, moving in upper-class British society. In 1870 he went to Karlsruhe, and subsequently moved on to Athens, where he stayed until 1879. In the summer of 1879 he went to Constantinople, where he was appointed Russian Ambassador, although he never entered upon the official duties. Then he was posted to Berlin (1880-1884), which involved him at the center of the secret negotiations that led to the unpublished pact, the League of the Three Emperors. In 1884 he left the diplomatic service and returned to Saint Petersburg.
