Attaleia in the context of "Pisidia"

Sagalassos (Greek: Σαγαλασσός), also known as Selgessos (Greek: Σελγησσός) and Sagallesos (Greek: Σαγαλλησός), is an archaeological site in southwestern Turkey, about 100 km north of Antalya (ancient Attaleia) and 30 km from Burdur and Isparta. The ancient ruins of Sagalassos are 7 km from Ağlasun (as well as being its namesake) in the province of Burdur, on Mount Akdağ, in the Western Taurus Mountains range, at an altitude of 1450–1700 metres.In Roman Imperial times, the town was known as the "first city of Pisidia", a region in the western Taurus Mountains, currently known as the Turkish Lakes Region. During the Hellenistic period it was already one of the major Pisidian towns.

Eumenes I (Ancient Greek: Εὐμένης) was dynast (ruler) of the city of Pergamon in Asia Minor from 263 BC until his death in 241 BC. He was the son of Eumenes, the brother of Philetaerus, the founder of the Attalid dynasty, and Satyra, daughter of Poseidonius. As he had no children, Philetaerus adopted Eumenes to become his heir.

Although nominally under Seleucid control, Pergamon under Philetaerus enjoyed considerable autonomy. However, upon his succession, Eumenes, perhaps with the encouragement of Ptolemy II, who was at war with the Seleucids, revolted, defeating the Seleucid king Antiochus I near the Lydian capital of Sardis in 261 BC. He was thus able to free Pergamon, and greatly increase the territories under his control. In his new possessions, he established garrison posts in the north at the foot of Mount Ida called Philetaireia after his adoptive father, and in the east, northeast of Thyatira near the sources of the river Lycus, called Attaleia after his grandfather, and he extended his control south of the river Caïcus to the Gulf of Cyme as well. Demonstrating his independence, he began to strike coins with the portrait of Philetaerus, while his predecessor had still depicted Seleucus I Nicator.
