Сигизмунд Кейстутович
Despite its strong fortifications, Lida was taken by the Teutonic Knights on several occasions (1384, 1392). Lithuanian Grand Duke Vytautas gave it to his ally, Khan Tokhtamysh, who settled "in a yurt near the castle". In 1406, the family of Yury of Smolensk was locked up in Lida as hostages; his attempt to take the castle and liberate them was not successful. In 1433, Lida was a point of contention between Švitrigaila and his cousin Sigismund Kęstutaitis.
