After the weakening of the Byzantine and the Bulgarian Empire in the 13th century, parts of the country has been captured by the Venetian and Serbian Empire.
In general, the invaders destroyed or weakened Roman and Byzantine cultural centers in Albania.
A part of this population later moved to Mycenae around 1600 BC and founded the Mycenaean civilisation there.
In ancient times, the territory of modern Albania was mainly inhabited by a number of Illyrian tribes.
This territory was known as Illyria, corresponding roughly to the area east of the Adriatic sea to the mouth of the Vjosë river in the south.
