All the senior Rus' princes, including Yaroslav II of Vladimir, Daniel of Galicia, and Sviatoslav III of Vladimir, acknowledged Batu's supremacy. Originally Batu ordered Daniel to turn the administration of Galicia over to the Mongols, but Daniel personally visited Batu in 1245 and pledged allegiance to him. After returning from his trip, Daniel was visibly influenced by the Mongols, and equipped his army in the Mongol fashion. Austrian visitors to his camp remarked that all of Daniel's horsemen dressed like Mongols. The only one who did not was Daniel himself, who dressed according to "the Russian custom." Michael of Chernigov, who had killed a Mongol envoy in 1240, refused to show obeisance and was executed in 1246.
