In 1483, Anna became the
regent of her sixteen-year son. In her policy, Anna tried to expand her domain, she visited often Moscow, and due her diplomatic efforts, the
Principality of Pronsk was added to Ryazan. A major issue in relations between Ryazan and Moscow was the so-called
ryazan ukraina, a huge
steppe region in the
basin of the
Don River. According to treaties, Ryazan was obliged not to settle in these lands, but over many years, the princes of Ryazan secretly colonized this area, and during the Anna's regency, this process became much more significant. Numerous immigrants received considerable privileges, being released for 3–7 years from taxes if they agreed to remain in the steppe for ever. Anna's son died in 1500, and until her death in 1501, she was the regent of her grandson
Ivan V of Ryazan. After the end of Anna's reign, Ryazan finally lost its independence. Aside from Ivan, Anna had a son called Fyodor and a daughter called Anna, who was married to Lithuanian prince Fyodor Ivanovich
Belsky. ==References==
