The province of Eordaia (Greek: Επαρχία Εορδαίας) was one of the provinces of the Kozani Prefecture. Its territory corresponded with that of the current municipality Eordaia, and a few villages of the municipality Kozani. It was abolished in 2006.
The history of Eordaia can be found stretching long before 2000 BCE when the first Greeks known as the Aeolians and Arcadians began to inhabit this area.[dubious– discuss] Remnants of copper mines exploited from 2700 up until 1200 BCE indicate strongly that the Greeks inhabited Eordaia for thousands of years. Iron mines have also been exploited in the region.
Within a 50-year period, paleontologists and archaeologists have made many discoveries due to the industrial development of the Eordaian countryside. In particular, the skeletal fossils of a prehistoric mammoth, a prehistoric elephant, and Stone Age tools have all been found within the province of Eordea. These finds add to knowledge on the variety of animal species and human artifacts in this particular region of western Macedonia.
