Yuri Dolgorukiy
Yuri I Vladimirovich (), commonly known as Yuri Dolgorukiy or the Long Arm (, meaning "Far-Reaching", c. 109915 May 1157) was the first Rurikid prince to rule in the northern territory of Rostov (later Vladimir-Suzdal). Noted for successfully curbing the privileges of the landowning "boyar" class in Rostov-Suzdal and his ambitious building programme, Yuri transformed his Kievan Rus' principality into the independent power that would evolve into early modern Muscovy.
