Anna of Ryazan

Some stories identify Anna's mother as the architect of the marriage between Anna and Vasily; she supposedly asked her son Ivan III to delay annexation of Ryazan because it was not suitable to a Grand Princess to marry an ordinary nobleman even of princely descent.

[7][8] In 1467 Anna bore a son Ivan and until the death of her husband in 1483 did not participate in governing the principality and did not protest when her brother two times annexed Ryazan territories.

In her policy Anna tried to expand her domain, she visited often Moscow and due her diplomatic efforts the Pronsk principality was added to Ryazan.

A major problem in Ryazan-Moscow relations was so-called ryazan ukraina, a huge steppe region in the basin of Don River.

Numerous immigrants received considerable privileges, being released for 3–7 years from taxes if agreed to remain in steppe for ever.
