Systematic massacres took place in 1894–1896 when Sultan Abdul killed 300,000 Armenians throughout the provinces. In 1909 government troops killed, in the towns of Adana alone, over 20,000 Christian Armenians. Also, in the first two decades of the 20th century, there were massacres of Greeks, Slavs, and Armenians in the Ottoman Empire, culminating in the Armenian, Greek and Assyrian genocides. As a result, the 20th century saw a sharp decline of the number of Orthodox Christians, and of Christians in general, in the Anatolian peninsula amidst complaints of Turkish governmental repression of various Eastern and Oriental Orthodox groups.
