What events shaped the rise of muslim arab empires and the eventual transfer of power to seljuk turks

During the reign of Maurice (r. 582-602), the Empire's eastern frontier was expanded and north stabilised. However, his assassination caused a two-decade-long war with Sassanid Persia which exhausted the Empire's resources and contributed to major territorial losses during the Muslim conquests of the 7th century. During the 10th-century Macedonian dynasty, the Empire experienced a golden age, which culminated in the reign of Emperor Basil II "the Bulgar-Slayer" (r. 976-1025). However, shortly after Basil's death, a neglect of the vast military built up during the Late Macedonian dynasty caused the Empire to begin to lose territory in Asia Minor to the Seljuk Turks.
