Antiquity

According to mythology, the ancient city of Agrinio (situated in the area of Megali Chora) was built by king Agrios, son of Portheus^[2] and a great-grandson of Aetolos (king of Plevron and Calydon) around 1600-1100 BC.

The town, built near the banks of river Achelous (the natural border between Aetolia and Acarnania), was claimed by both states during ancient times. Agrinio became member of the Aetolian League and it was later destroyed by Cassander in 314 BC during the League's wars against the Kingdom of Macedonia.

Ottoman era

The city reappears during the Ottoman period with the name Vrachori and apart from its Greek population it was also inhabited by many Turks (Muslims). In 1585 it was deserted during the revolt of Theodoros Migas. At the beginning of the 18th century, it became the administrative centre of Aetolia-Acarnania (then as the sanjak of Karleli), depended on the imperial harems. Vrachori participated in the Greek Revolution and was temporarily liberated, by an army group led by Alexakis Vlachopoulos, on June 11, 1821. In August 1822, while Reşid Mehmed Pasha's (Kütahi) troops were marching towards Vrachori, its citizens decided to burn and evacuate their city, following the strategy of scorched earth. The deserted city was recaptured by the Turks. The city was finally included in the borders of the newborn Greek state permanently in 1832 with the Treaty of Constantinople (July 9, 1832) and was renamed after its ancient name, Agrinion.

Modern era

In the years following the liberation, Agrinio went through an important growth and development, especially at the end of the 19th century and the dawn of the 20th. After the Greco-Turkish War and the Asia Minor Catastrophe, many refugees from Asia Minor (western Turkey) arrived in the city and settled in the district of Agios Konstantinos. At the same period there was an important internal immigration to Agrinio from the whole Aetolia-Acarnania region, along with immigration from the areas of Epirus and Evrytania.

During the Interwar period, in spite of economical crisis, works of infrastructure took place in the city, like the paving of streets and the installation of electricity, and a water tower was installed in 1930. At the same time excavations revealed the ancient city of Agrinion. Growth and prosperity returned after World War II and the Greek Civil War. This growth was boosted by the building of two major hydroelectric dam installations at Kremasta and Kastraki, on the north of the city. The tobacco industry and olive tree cultivation became the main income sources of the city.

On April 10, 2007, the city was struck by several earthquakes, with their epicenter located in the nearby Lake Trichonis on the southeast of the city. The first earthquake rumbled at around 2:20 AM, the second around 6:15 AM, three earthquakes shook at 10:13, 10:14 and 10:15 AM, and the last one at around 13:45 PM, they measured between 5.0 and 5.7 on the Richter scale.

City Seal

The city's official seal includes a characteristic moment of the ancient Greek mythology. More specifically, the seal depicts Hercules fighting the river-god Achelous. According to the myth, Hercules fought against the river-god for the sake of Diianira, the princess of Calydon, which both of them wanted as a wife. Despite Achelous' transformations, Hercules managed to win the battle and married the princess. According to Strabo, the myth symbolises the struggle of ancient Aetolians to control the river's power with embankments, by which the river was confined to its bed and thus the area gained large tracts of land for cultivation.
