Lyapin
Lyapin was a Mansi principality on the Lyapin and Northern Sosva rivers in western Siberia. The principality emerged in the 15th century.
Lyapin traded with Sosva and allied with Obdorsk. A Moscow expedition attacked it in 1499 without destroying it. Prince Luguy accepted Russian overlordship and tribute obligations in 1586; his son Shatrov joined a rising in 1607 and was captured and hanged. The principality then broke into smaller districts.
