What happened
After defeating the Taira clan at Dannoura in 1185, Minamoto no Yoritomo deliberately distanced his new government from Heiankyo (Kyoto) and the officials who might still hold loyalty to the old regime. In 1192 he had himself established as shogun, or military dictator, becoming, in World History Encyclopedia's words, the first to offer "an alternative to the power of the emperor and imperial court." His government, based at Kamakura, was called the bakufu, meaning "tent government," a term referring to its origin as the title of a field commander, and it operated on a feudal relationship between lord and vassal rather than the old court bureaucracy.
Why it matters
Yoritomo's shogunate created a durable dual-government structure, an emperor retaining ceremonial legitimacy in Kyoto while a shogun actually ruled from elsewhere, that would define Japanese politics for nearly 700 years, through the Ashikaga and Tokugawa shogunates, until the Meiji Restoration abolished it in 1868.
How we know
Yoritomo's title and the Kamakura bakufu's structure are documented in period administrative and legal records, including the offices of jito (land stewards) and shugo (military governors) he created to administer territory outside the old court system.
