Was part of the Byzantine empire in 565 A.D. (CE) and 1360A.D. (CE)?

In 565 A.D., the Byzantine Empire was at its height under Emperor Justinian I, encompassing parts of the Eastern Mediterranean, the Balkans, and North Africa. By 1360 A.D., however, the empire had significantly diminished in size and power, facing territorial losses to the Ottoman Turks and internal strife. This decline marked the gradual erosion of Byzantine influence, leading to its eventual fall in 1453. Thus, while both dates are within the timeline of the Byzantine Empire, they represent distinct phases of its expansion and contraction.
