On August 17, 1944 the Executions of Kokkinia took place. It was the largest Nazi roundup and one of the largest-scale war crimes committed during the German occupation of Greece.
Nikaia, like many other places around Greece, owes its population eruption to Greek refugees who were forced out of Asia Minor after the 1919-1922 Greco-Turkish war ended. It was part of the municipality of Piraeus until 1933, when it became a separate municipality, then still under the name Nea Kokkinia. It was renamed to Nikaia in 1940.
