During his five-year stay in the Ottoman Empire, Charles XII corresponded with his sister (and eventual successor), Ulrika Eleonora. According to Mrs. Ragnhild Marie Hatton, a Norwegian-British historian, in some of those letters Charles expressed his desire for a peace treaty which would be defensible in the future Swedish generations' eyes. However, he emphasized that only a greater respect for Sweden in Europe would enable him to achieve such a peace treaty. Meanwhile, the Swedish Council of State (government) and Estates/Diet (Parliament) tried to keep the beleaguered Sweden somehow organized and independent. Eventually, in the autumn of 1714, their warning letter reached him. In it, those executive and legislative bodies told the absentee King that unless he quickly returned to Sweden, they would independently conclude an achievable peace treaty with Russia, Poland and Denmark. This stark admonition prompted Charles to rush back to Sweden.
