Gathering of the Russian lands

The gathering of the Russian lands or Rus' lands (Russian: собирание русских земель) was the process in which new states – usually the Principality of Moscow and the Grand Duchy of Lithuania – acquired former territories of Kievan Rus' from the 14th century onwards, claiming to be its legitimate successor. In Russian historiography, this phenomenon represented the consolidation of a national state centered on Moscow.
