ABSTRACT
After Anna Ivanovna, Tsarina of Russia, died in 1740, Euler found the political climate in St. Petersburg increasingly uncomfortable. e infant Ivan VI’s ascent to the Russian throne (whose horoscope Euler had been asked to cast but instead quietly passed on to the court astrologer) provided yet another occasion for a power vacuum with yet another diffi cult regency . Once again, relatives in the royal family viciously competed with one another for power. Within a year, a palace revolt placed Peter the Great ’s daughter, Elisavetta Petrovna , on the throne, where she would remain for 20 years. When she assumed power, the atmosphere within the academy became less and less congenial.
