Most of the areas which today are within modern
Greece's borders were at some point in the past a part of the
Ottoman Empire. This period of Ottoman rule in Greece, lasting from the mid-15th century until the successful
Greek War of Independence that broke out in 1821 and the establishment of the modern Greek state in 1832, is known in Greek as
Tourkokratia (, "Turkish rule"; ). Some regions, however, like the
Ionian islands or
Mani in
Peloponese were never part of the Ottoman administration, although the latter was under Ottoman
suzerainty.
