ユーリー・ドルゴルーキー
In 1147 Yuri Dolgorukiy had a meeting with Sviatoslav Olgovich (then prince of Belgorod Kievsky) in a place called Moscow. In 1156 Yuri fortified Moscow with wooden walls and a moat. Although the settlement probably existed later or earlier, Dolgorukiy is often called "the Founder of Moscow".
