Marta Skavronskaya was married for 8 days and not years to a Swedish army trumpet player. She liked her brother Karl and brought the others to Russia after the death of her husband because her sister Christine hd made a public petition in her name and she rounded up her, her sister Anna and brother Theodore and put them on an estate Strelna, twenty miles from St. Petersburg and never went to see them. It can be concluded that with the exception of Karl who had a large house near her own and was brought to Moscow in 1723, the others were brought there to shut them up though she made them aristocrats and educated their children.
She was the child of runaway serfs from Belarus and Latvia. She was born in Vishki Latvia and was very lucky. Her parents died of the plague. She was raised by an aunt who brought her to a clergyman and he brought her to his supervisor the famous theologian Ernst Gluck. They raised her as a ward and arranged her marriage to Johann Kruse. After eight days the Russians invaded and at 18 became the mistress of the field General, then the head of the Russian forces in the West and then Menshikov took her knowing the Tzar would like her.
She was mistress to the Tzar, which was a job in and of itself. He slept with everyone in the world. He loved and trusted her. She was described as beautiful when young, and later by a German diplomat as having lost any trace of beauty but being very graceful and gentle. Her reputation was that she was a moderating influence on the Tzar.
Finally she did not sleep with Mons but was involved in a corrupt scheme in which he and his sister charged to talk to her and she took bribes to introduce people to Peter. She hid the money from Peter in Holland. When he found out he had fought a life long battle against corruption. He was furious at this betrayal and he turned to Maria Cantimir in that time. He canceled the accounts of Marta and for three months they did not talk. Then they made up. Maria did not get put in a convent, but after the death of Peter, Marta threw her out of the palace, she had been a lady in waiting, and she never married but ran a literary salon.
Catherine continued the work of Peter and though she drank and had lovers, did a very good job. Whatever he would have wanted she did.
