What happened
Ivan III became Grand Prince of Moscow in 1462, inheriting a city that already had major advantages: the seat of the Russian Orthodox Church since the 14th century and a position on trade routes between Novgorod and the Volga. Over his reign he annexed rival cities including Yaroslavl in 1463, Rostov in 1474, and most significantly Novgorod, Moscow's chief northern rival, folding them under Moscow's authority. He commissioned Italian architects to rebuild the Kremlin's towers and walls in the 1480s and 1490s, physically marking Moscow's new status. He was the first Rus prince to call himself Tsar, though the title would not be formalized until his grandson Ivan IV.
Why it matters
Historians call this process the Gathering of the Russian Lands, and it created the first real predecessor of a unified Russian state, ending the era of competing appanage principalities that had let the Mongols pick off Rus cities one at a time in 1237-1240. It set up the political framework his grandson Ivan IV would use to declare himself Tsar of all Russia.
How we know
Muscovite chronicles and land records document the annexations of Yaroslavl, Rostov, and Novgorod; the Kremlin's Italian-built towers and walls from the 1480s-1490s survive today as physical evidence of the building program.
