İzmit is a city in Turkey. It is the main city and capital of Kocaeli Province. İzmit is located on the Gulf of İzmit, which is part of the Sea of Marmara. It is about 100 kilometers (62 miles) east of Istanbul.

In ancient times, İzmit was known as Nicomedia. It was a very important city in the Roman Empire. Between 286 and 324 AD, it was one of the Roman Empire's capital cities. This was during a time called the Tetrarchy, started by Emperor Diocletian. Later, after Emperor Constantine the Great won a big battle in 324 AD, Nicomedia became his temporary capital. He then built a new capital city nearby, which he called New Rome (later known as Constantinople, and today as Istanbul). Constantine died near Nicomedia in 337 AD. During the Ottoman Empire, İzmit was also an important regional capital.

What's in a Name?

The name "İzmit" comes from the ancient Greek name of the city, Nicomedia. It's similar to how the name "Istanbul" came to be. Before Turkey officially started using the Latin alphabet, people sometimes spelled İzmit as Ismid or Iskimid.

Where is İzmit Located?

İzmit is located between 40°-41° North and 29°-31° East. To the south, it has the Gulf of İzmit. To the west, you'll find Istanbul and the Sea of Marmara. The Black Sea is to the north, and Sakarya Province is to the east.

The city is mostly built on hills because the flat land near the sea is quite small. This means İzmit has two main parts. The city center is on the flat plains near the sea. Important roads and railways pass through this area. The second part of the city is built on the hills. Here, you can find many old houses from the Ottoman Empire period.

A Look Back at İzmit's History

Long ago, around 712 BC, the city was called Astacus or Olbia. After it was destroyed, it was rebuilt in 264 BC by Nicomedes I of Bithynia. He named it Nicomedia. This city became one of the most important places in northwestern Asia Minor.

A famous general from Ancient Carthage named Hannibal spent his last years in Nicomedia. He died nearby between 183 and 181 BC. The historian Arrian was also born in Nicomedia.

In 286 AD, the Roman Emperor Diocletian made Nicomedia the eastern capital of the Roman Empire. It stayed a capital until 324 AD, when Licinius was defeated by Constantine the Great. Constantine lived in Nicomedia as his temporary capital for six years. In 330 AD, he declared the nearby city of Byzantium as the new capital, calling it Nova Roma. This city later became known as Constantinople (modern Istanbul). Constantine passed away near Nicomedia on May 22, 337 AD. Even after Constantinople was founded, Nicomedia remained important because many roads from Asia led to the new capital through it.

İzmit was under Byzantine rule until the late 11th century. Then, it was captured by the Seljuk Turks. However, the city soon returned to Byzantine control after the First Crusade. After Constantinople was attacked in 1204 during the Fourth Crusade, Nicomedia became part of the Latin Empire. The Byzantines took it back around 1235. The city remained Byzantine until the Ottoman Turks conquered it in 1337.

During the Turkish War of Independence, İzmit was occupied by the United Kingdom on July 6, 1920. The British then handed it over to Greece on October 27, 1920. Turkish forces took İzmit back on June 28, 1921.

A very strong earthquake, measuring 7.6 on the Mercalli intensity, hit the region on August 17, 1999. This earthquake caused a lot of damage. More than 17,000 people died, and half a million people lost their homes. It took several years for the city to recover from this disaster.
