Charlotte enjoyed the favour of Tsar Peter the Great, but lived an isolated life with her own court, which was composed almost entirely by foreigners and headed by her first cousin, Princess Juliana Luise von Ostfriesland. In the beginning her marriage to Alexei was happy, but his drunkenness soon began to strain their relationship. Peter the Great also often took his son on war campaigns with him, thus even further isolating Charlotte. In the early weeks of their marriage, Peter ordered her to return to Petersburg without him or his son, but she had run back to her father's palace. Peter was the one who retrieved her, but soothed her instead of showing anger, and told her that she was free to visit her family whenever, but would have to tell him in the future. The tsesarevich also had an open affair with Yefrosinya Fedorov which started during Charlotte's short lifetime and continued after her death. Charlotte found some consolation in the birth of a daughter, Natalia, and a son, later Peter II of Russia. She died a month after the birth of her son. Both her daughter and son died young without issue.
