When did the Byzantine Empire take control of Bulgaria?

The Byzantine Empire gained full control over Bulgaria in 1018, marking the end of the first Bulgarian empire.123

This annexation followed a prolonged and methodical military campaign led by the Byzantine emperor Basil II, who sought to crush the resistance of the Bulgarian tsar Samuel. After a decisive victory in 1014 and the subsequent collapse of Bulgarian defenses, the territory was incorporated into the Byzantine Empire and divided into three administrative themes. Bulgaria remained under Byzantine rule for more than a century and a half, until a successful anti-Byzantine revolt in 1185 led to the establishment of the second Bulgarian empire.4315
