The most famous of the brothers was Prince Mikhail Ivanovich Vorotynsky. He was one of those commanders who led the conquest of Kazan in 1552 and was the first to take the Arsk Tower. In 1561 the prince was exiled to Beloozero, and his estates were confiscated. Four years later, he was let out on bail and dispatched to govern Kazan. For ten years, Mikhail Vorotynsky was in charge of Russian southern borders, founding new forts and strengthening the Great Abatis Belt. His bold leadership made itself felt at the Battle of Molodi, where he routed the 120,000-strong Tatar army in the three-day battle (1572).
