Yury Dolgoruky, Dologoruky meaning of the long hands/arms (Юрий Долгорукий in Russian) (1099? - May 15, 1157), Prince of Suzdal, Grand Prince of Kiev, sixth son of Vladimir Monomakh, founder of Moscow. His birthdate is uncertain; however, the chronicles report that Yury's elder brother, Vyacheslav, said to him: "I am much older than you; I was already bearded when you were born." Since Vyacheslav was born in the early 1080s, this pushes Yury's birth to c. 1099/1100.

During his father's reign, Yuri governed the Rostov-Suzdal province. After the death of the Grand Prince of Kiev Mstislav Vladimirovich in 1132, Yuri engaged in a process of conquering the lands to the south of his domain (hence, the nickname Dolgoruky, i.e. Long Arms), trying to subjugate Pereyaslavl (today's Pereyaslav-Khmelnitsky) and then Kiev. The first stage of his struggle (1132-1135) turned out unsuccessful.

During Yuri's reign, the borders of his principality started to take a more concrete shape (especially with bordering Feudal Republic of Novgorod and Principality of Chernigov). A number of fortresses were built along the borders (Ksnyatin (probably, today's Tver), Dubna etc.) and in the center of Yuri's principality (Pereyaslavl (Pereyaslavl-Zalessky), Yuriev-Polsky, Dmitrov and others).

In 1147, Yuri Dolgoruky had a meeting with the Prince of Novgorod-Seversky Svyatoslav Olgovich in a place called Москва (Moskva, or Moscow). This first mentioning of Moscow is considered the traditional date of the city's founding. In 1156, Yuri fortified Moscow with new wooden walls and a moat.

In 1147, Dolgoruky resumed his struggle for Kiev and two years later he captured it, but in 1151 he was defeated by Izyaslav Mstislavich and ousted. In 1155, Yuri regained Kiev once again, however, after his death in the course of an uprising in Kiev his achievements were eliminated.

In 1954, a monument was erected to Yuri Dolgoruky as a founder of Moscow. Dolgoruky's image was stamped on a medal "In commemoration of Moscow's 800th anniversary", introduced in 1947.
