History of Kos Island

Early Days

Kos Island was under the colony of the Carians during its formative years. The Carians are a group of sea-faring people who predated the Minoans. The Dorians later on inhabited the island following the War of Troy during 11th century BC. Its strategic location, beauty, and fertile land made it in demand among people throughout history and its exceptional past was formed by several alternating reigns. 

One of the earliest recorded milestones of Kos history was the 5th century BC when the famous physician and philosopher Hippocrates was born here.

Hellenistic Period

During the Hellenistic period, Kos Island was a center of culture, arts, and sciences. The famous sculptor Praxiteles created many masterpieces here, and the island was also home to renowned philosophers like Philitas of Cos and Theodoros.

The island also played a significant role in early Christianity, with several churches and monasteries built during this period.

Byzantine Period

From the 4th century AD until the island was conquered by the Ottoman Empire in the 16th century, Kos was part of the Byzantine Empire. During this time, the island played an important role in the empire’s economy and strategic defenses, as it was a key stop on the maritime trade routes connecting the east and west. The island suffered from frequent pirate attacks, and its population declined significantly during this time.

Middle Ages

In the 14th century, the Knights Hospitaller, established their presence on the island. They built a fortress in the heart of the island, which served as their headquarters and a refuge for the island’s inhabitants during times of war and unrest.

The castle itself was transformed into a magnificent stronghold with impressive fortifications, towers, and underground tunnels.

However, the Knights’ rule was not without conflict. In 1457, the Ottoman Turks attacked and seized the island, ending the Knights’ reign. The Turks used the castle as a garrison and prison, and much of the fortress was destroyed during this period.
