Achaia

Achaia is a region in the northern Peloponnese in southern Greece. It borders the southern coast of the Gulf of Corinth. The largest city of the region is Patras, one of Greece's busiest ports in terms of its connections to Italy.

The name Achaia has been used with two distinct meanings: a geographical one referring to the region as it exists today, and a historical one referring to various populations and political entities in different periods. The failure to distinguish between these two meanings has often caused confusion when reading ancient texts.

Geography

The region consists of an extensive and winding coastline bordered to the south by mountains. The Panachaiko range and the central mountain chain of the Peloponnese separate the coast from the interior. Short rivers flow from the mountains and empty into the Gulf of Corinth. The coastal plain is cultivated with vines, olives, and fruit.

The Achaean League

During the Hellenistic period, the cities of the region formed a political and military association known as the Achaean League. The league brought together various city-states, had a common assembly, and elected leadership. It became one of the major powers of the Peloponnese until the Romans took control of the region.

After the Romans conquered the region, the name Achaia was applied to a Roman administrative province larger than the original area, encompassing most of southern Greece. Consequently, in Roman writings, "Achaia" generally referred to southern Greece as a whole, not merely to the small region.

Present day

Today Achaia is an administrative unit within the Western Greece region. The economy depends on agriculture, the port of Patras, universities, and coastal commerce. The bridge linking the Peloponnese to mainland Greece near Patras has significantly increased road connections.
