Peter III of Russia
Empress Elizabeth arranged for Peter to marry his second cousin, Sophia Augusta Frederica (later Catherine the Great), daughter of Christian August, Prince of Anhalt-Zerbst and Johanna Elisabeth of Holstein-Gottorp. The young princess formally converted to Russian Orthodoxy and took the name Ekaterina Alexeievna (i.e., Catherine). They married on 21 August 1745. The marriage was not a happy one but produced one son, the future Emperor Paul, and one daughter, Anna Petrovna (20 December 1757 – 19 March 1759). Catherine later claimed that Paul was not fathered by Peter: that, in fact, they had never consummated the marriage. During the sixteen years of their residence in Oranienbaum, Catherine took numerous lovers, while her husband did the same in the beginning.
Catherine I of Russia
Catherine was the first woman to rule Imperial Russia, opening the legal path for a century almost entirely dominated by women, including her daughter Elizabeth and granddaughter-in-law Catherine the Great, all of whom continued Peter the Great's policies in modernizing Russia. At the time of Peter's death the Russian Army, composed of 130,000 men and supplemented by another 100,000 Cossacks, was easily the largest in Europe. However, the expense of the military was proving ruinous to the Russian economy, consuming some 65% of the government's annual revenue. Since the nation was at peace, Catherine was determined to reduce military expenditure. For most of her reign, Catherine I was controlled by her advisers. However, on this single issue, the reduction of military expenses, Catherine was able to have her way. The resulting tax relief on the peasantry led to the reputation of Catherine I as a just and fair ruler.
