World War II: Holocaust of Kedros in Crete by German forces.

The Holocaust of Kedros, also known as the Holocaust of Amari, was the mass murder of the civilian residents of nine villages located in the Amari Valley on the Greek island of Crete during its occupation by the Axis powers in World War II. The massacre was a reprisal operation mounted by Nazi German forces.

Crete is the largest and most populous of the Greek islands, the 88th largest island in the world, and the fifth largest island in the Mediterranean Sea, after Sicily, Sardinia, Cyprus, and Corsica. Crete is located approximately 100 km (62 mi) south of the Peloponnese, and about 300 km (190 mi) southwest of Anatolia. Crete has an area of 8,450 km² (3,260 sq mi) and a coastline of 1,046 km (650 mi). It bounds the southern border of the Aegean Sea, with the Sea of Crete to the north and the Libyan Sea to the south. Crete covers 260 km from west to east but is narrow from north to south, spanning three degrees of longitude but only half a degree of latitude.
