In recent history, on 22 July 1967, a strong, 7.2 Richter magnitude scale earthquake hit Geyve and had given considerable damage to the town. On 17 August 1999, Geyve, despite the proximity to epicenter of earthquake, was not destroyed as the neighboring Adapazarı and Gölcük. Unfortunately, Turkish earthquake scientists had made several worrying reports that the next expected Marmara earthquake could impact Geyve and Akyazı region as there had been an additional fault under Geyve, which had not broken in the last 300 years. Some of the Turkish media reports regarding the statements can be found at the following links; ,

There is not enough scientific evidence available regarding the first settlers of Geyve. The ruins around the region do not survive, but it is almost certain that Geyve is an historical settlement dating back thousands of years. There are different claims that its origin goes to 4000 BC, and even some sources to 10000 BC. Geyve region has been inhabited by Phrygians, Hitites, Lydians, Romans, Armenians, Byzantines, Turks and many other civilizations since prehistoric times. Many historical evidence from Byzantine and Roman Empire era have been discovered in Geyve. Geyve was known to be one of the early Ottoman conquests. It was conquered by Osman Gazi (reigned c. 1299–1323/4), first Ottoman Sultan, in the 14th century from Byzantine Empire.
The demography of the town has been significantly impacted by the population exchange between Greece and Turkey in 1923. Before 1923, the town had considerable Rum (Eastern Roman, Greek) and Armenian populations along with Turks. Several old photographs and evidence have been collected by a local researcher-collector in the following link.
The origin of Geyve's name is controversial. Evliya Celebi, famous Turkish-Ottoman traveller, in his Seyahatname states that Geyve's name comes from the Byzantine princess named Gekve.
Geyve was one of the symbolic towns in the Turkish War of Independence (1919–1922). Geyve Gorge had a strategic importance during the War of Independence.

The founder of the Turkish Republic, Mustafa Kemal Ataturk, visited Geyve two times in 1920 and 1922 during the War of Independence.
The most significant landmark of the town,the old bridge over Sakarya River in Alifuatpasa, was constructed in the era of Sultan Bayezid II of Ottoman Empire (reigned 1481–1512). The bridge was kept well by Ottoman Sultans as the bridge is strategically located on the Silk Road.One of the oldest photographs of the bridge (from around 1888) by a Swedish photographer, Guillaume Berggren, is depicted in the National Gallery of Canada.
Another significant landmark is Elvanbey Imarethanesi,(Public Kitchen), which was constructed in 1451 by Elvanbey. It was told to be serving to the traveling dervishes of Anatolia. The building was used as Geyve Public Library between 1969 and 2013. In 2013, the building was converted to a museum.
One of the most prominent generals of Turkish War of Independence, Ali Fuat Cebesoy was buried in Alifuatpasa, Geyve, when he died at the age of 86 in 1968.
