Bergama in the context of "İzmir Province"

Aelius Galenus or Claudius Galenus (Greek: Κλαύδιος Γαληνός; September 129 – c. 216 AD), often anglicized as Galen (/ˈɡeɪlən/) or Galen of Pergamon, was a Roman and Greek physician, surgeon, and philosopher. Considered to be one of the most accomplished of all medical researchers of antiquity, Galen influenced the development of various scientific disciplines, including anatomy, physiology, pathology, pharmacology, and neurology, as well as philosophy and logic.

The son of Aelius Nicon, a wealthy Greek architect with scholarly interests, Galen received a comprehensive education that prepared him for a successful career as a physician and philosopher. Born in the ancient city of Pergamon (present-day Bergama, Turkey), Galen traveled extensively, exposing himself to a wide variety of medical theories and discoveries before settling in Rome, where he served prominent members of Roman society and eventually was given the position of personal physician to several emperors.

Pergamon or Pergamum (/ˈpɜːrɡəmən/ or /ˈpɜːrɡəmɒn/; Ancient Greek: Πέργαμον), also referred to by its modern Greek form Pergamos (Πέργαμος), was a rich and powerful ancient Greek city in Aeolis. It is located 26 kilometres (16 mi) from the modern coastline of the Aegean Sea on a promontory on the north side of the river Caicus (modern-day Bakırçay) and northwest of the modern city of Bergama, Turkey.

During the Hellenistic period, it became the capital of the Kingdom of Pergamon in 281–133 BC under the Attalid dynasty, who transformed it into one of the major cultural centres of the Greek world. The remains of many of its monuments are still visible today, most notably the masterpiece of the Pergamon Altar. Pergamon was the northernmost of the seven churches of Asia cited in the New Testament Book of Revelation.

Attalus I (Ancient Greek: Ἄτταλος 'Attalos'), surnamed Soter (Greek: Σωτήρ, 'Savior'; 269–197 BC), was the ruler of the Greek polis of Pergamon (modern-day Bergama, Turkey) and the larger Pergamene Kingdom from 241 BC to 197 BC. He was the adopted son of King Eumenes I, whom he succeeded, and the first of the Attalid dynasty to assume the title of king, sometime around 240 to 235 BC. He was the son of Attalus and his wife Antiochis.

Attalus won an important victory, the Battle of the Caecus River, over the Galatians, a group of migratory Celtic tribes from Thrace, who had been plundering and exacting tribute throughout most of Asia Minor for more than a generation. The victory was celebrated with a triumphal monument at Pergamon (The Dying Gaul) and Attalus taking the surname "Soter" and the title of king. He participated in the first and second Macedonian Wars against Philip V of Macedon as a loyal ally of the Roman Republic, although Pergamene participation was ultimately rather minor in these wars. He conducted numerous naval operations throughout the Aegean, gained the island of Aegina for Pergamon during the first war and Andros during the second, twice narrowly escaping capture at the hands of Philip V. During his reign, Pergamon also repeatedly struggled with the neighboring Seleucid Empire to the east, resulting in both successes and setbacks.

The Karasids or Karasid Beylik (Ottoman Turkish: قرا صـی; Turkish: Karesioğulları Beyliği), also known as the Principality of Karasi, was a Turkish Anatolian beylik (principality) in the area of classical Mysia (modern Balıkesir and Çanakkale provinces) from ca. 1297–1345. It was centered in Balıkesir and Bergama, and was one of the frontier principalities established by Oghuz Turks after the decline of the Seljuk Sultanate of Rum.

They became a naval power in the Aegean and the Dardanelles.

The Library of Pergamum (Greek: Βιβλιοθήκη του Πέργαμον) is an ancient Greek building in Pergamon, Anatolia, today located nearby the modern town of Bergama, in the İzmir Province of western Turkey. It was one of the most important libraries in the ancient world.
