No evidence remains of major resistance or any uprising of the Bulgarian population or nobility in the first decade after the establishment of Byzantine rule. Given the existence of such irreconcilable opponents to the Byzantines as Krakra, Nikulitsa, Dragash and others, such apparent passivity seems difficult to explain.

Basil II guaranteed the indivisibility of Bulgaria in its former geographic borders and did not officially abolish the local rule of the Bulgarian nobility, who became part of Byzantine aristocracy as archons or strategoi. Secondly, special charters (royal decrees) of Basil II recognised the autocephaly of the Bulgarian Archbishopric of Ohrid and set up its boundaries, securing the continuation of the dioceses already existing under Samuil, their property and other privileges.

After the death of Basil II the empire entered into a period of instability. In 1040, Peter Delyan organized a large-scale rebellion, but failed to restore the Bulgarian state and was killed. Shortly after, the Komnenos dynasty came into succession and halted the decline of the empire. During this time the Byzantine state experienced a century of stability and progress.

In 1180 the last of the capable Komnenoi, Manuel I Komnenos, died and was replaced by the relatively incompetent Angeloi dynasty, allowing some Bulgarian nobles to organize an uprising. In 1185 Peter and Asen, leading nobles of supposed and contested Bulgarian, Cuman, Vlach or mixed origin, led a revolt against Byzantine rule and Peter declared himself Tsar Peter II. The following year, the Byzantines were forced to recognize Bulgaria's independence. Peter styled himself "Tsar of the Bulgars, Greeks and Wallachians".
