Principality of Korela
In the 1330s, the Novgorod Republic gave the castle of Korela (and practically the entire Votian fifth, including the forts of Oreshek and Ladoga) to duke Narimantas of Lithuania. In 1383 Korela, Oreshek and Koporye were inherited by Narimantas' son and heir, Patrikas, the forefather of the Galitzine princely clan. Next year the local burghers lodged a complaint about his administration. Patrikas was forced to exchange Korela for Ladoga and Russa. Patrikas occupied his lands in Ingria and Karelia at least from 1383 to 1397. In the year 1408, it is recorded that he settled in Moscow under the protection of Vasili I, together with his younger sons, Georgi and Fyodor, who had grown up in Ingria.
