Uprising of Ivaylo
The Uprising of Ivaylo (Bulgarian: Въстанието на Ивайло) was a rebellion of the Bulgarian peasantry against the incompetent rule of Emperor Constantine Tikh and the Bulgarian nobility. The revolt was fuelled mainly by the failure of the central authorities to confront the Mongol menace in north-eastern Bulgaria.
