  The first known reference to Moscow was in 1147, as a meeting place of Yuri Dolgorukiy and Sviatoslav Olgovich. At the time it was a minor town on the western border of Vladimir-Suzdal Principality. The chronicle says, "Come, my brother, to Moskov". In 1156, Dolgorukiy fortified the town by creating a wooden wall; this structure became the Kremlin. In the course of the Mongol invasion of Kievan Rus', the Mongols under Batu Khan burned the city to the ground and killed its inhabitants.
  
  The timber fort na Moskvě "on the Moscow River" was inherited by Daniel, the youngest son of Alexander Nevsky, in the 1260s, at the time considered the least valuable of his father's possessions. Daniel was still a child at the time, and the big fort was governed by tiuns (deputies), appointed by Daniel's paternal uncle, Yaroslav of Tver. Daniel came of age in the 1270s and became involved in the power struggles of the principality with lasting success, siding with his brother Dmitry in his bid for the rule of Novgorod. From 1283 he acted as the ruler of an independent principality alongside Dmitry, who became Grand Duke of Vladimir. Daniel has been credited with founding the first Moscow monasteries, dedicated to the Lord's Epiphany and to Saint Daniel.
