19th century, out of the approximately 730,000 (per the Greek census of 1879) inhabitants of the Peloponnese, and the three neighboring islands of Poros, Hydra and Spetses, Arvanites numbered 90,253 (or 12.3%) in total according to Alfred Philippson; while in a critical response to Philippson's study the same year, Christos Koryllos supported 50,352 (or 6.9%) for the Peloponnese and 20,685 for the three aforementioned islands, totalling 71,037 (or 9.7%). Ottoman conquest, Venetian interlude and Ottoman reconquest The Venetian fortresses were conquered in a series of Ottoman-Venetian Wars: the first war, lasting from 1463 to 1479, saw much fighting in the Peloponnese, resulting in the loss of Argos, while Modon and Coron fell in 1500 during the second war. Coron and Patras were captured in a crusading expedition in 1532, led by the Genoese admiral Andrea Doria, but this provoked another war in which the last Venetian possessions on the Greek mainland were lost. Following the Ottoman conquest, the peninsula was made into a province (sanjak), with 109 ziamets and 342 timars. During the first period of Ottoman rule (1460–1687), the capital was first in Corinth (Turk. Gördes), later in Leontari (Londari), Mystras (Misistire) and finally in Nauplion (Tr. Anaboli). Sometime in the mid-17th century, the Morea became the centre of a separate eyalet, with Patras (Ballibadra) as its capital. Until the death of Suleiman the Magnificent in 1570, the Christian population (counted at some 42,000 families c. 1550) managed to retain some privileges and Islamization was slow, mostly among the Albanians or the estate owners who were integrated into the Ottoman feudal system. Although they quickly came to control most of the fertile lands, Muslims remained a distinct minority. Christian communities retained a large measure of self-government, but the entire Ottoman period was marked by a flight of the Christian population from the plains to the mountains. This occasioned the rise of the klephts, armed brigands and rebels, in the mountains, as well as the corresponding institution of the government-funded armatoloi to check the klephts activities. With the outbreak of the "Great Turkish War" in 1683, the Venetians under Francesco Morosini occupied the entire peninsula by 1687, and received recognition by the Ottomans in the Treaty of Karlowitz (1699). The Venetians established their province as the "Kingdom of the Morea" (It. Regno di Morea), but their rule proved unpopular, and when the Ottomans invaded the peninsula in 1715, most local
