Gediminid Belsky family

The Belsky or Belski family (Russian: Бельский; plural: Бельские) was a princely family of Gediminid origin in the Grand Duchy of Lithuania. It later deflected to the Grand Duchy of Moscow and played a key role during the regency of Ivan IV of Russia. The family started with Ivan Vladimirovich, son of Vladimir Olgerdovich and grandson of Algirdas, and ended with Ivan Dmitrievich Belsky in 1571. The Belsky name was derived from their principal possession of Bely, Tver Oblast.

Ivan Vladimirovich was first mentioned in written sources as a witness to the 1422 Treaty of Melno. After the death of Grand Duke Vytautas in 1430, Ivan was involved in the ensuing power struggle. Initially he supported Švitrigaila and witnessed the anti-Polish Treaty of Christmemel with the Teutonic Knights. However, he changed sides and actively supported the 1432 coup against Švitrigaila in favor of Sigismund Kęstutaitis. He then changed sides again and fought against Sigismund in the decisive Battle of Pabaiskas in 1435. Ivan was taken prisoner during the battle. Around 1444, he was invited by the Novgorod Republic to govern their city. However, his reign lasted only about a year and his further fate is unknown. Ivan married Vasilisa Olshanska, sister of Queen of Poland Sophia of Halshany. They had three sons – Ivan (married Princess Vorotynska), Simeon (married to daughter of Yury Patrikeyevich and Maria Vasilievna), Feodor – and three daughters. The daughters were married to Bolesław II of Cieszyn, to Ivan Ostrogski, and to the voivode of Kiev Ivan Chodkiewicz.
