416 TWO EPILOGUES
The military threat came in several waves. The Fourth Crusade and the period
of the Latin Empire (1204–1261) had wreaked devastating violence on the coun-
tryside. As the westerners gobbled up whatever they could of Greek land and
wealth, the Saljuq Turks and Egyptian Mameluks carved up the Holy Land and
Anatolia between them, while most of the Balkans were taken over by the Bulgars
and Serbs. The onslaught of the Mongols in the thirteenth century had shaken
matters up even more by destroying the ’Abbasid caliphate, threatening the Bul-
gars (who in turn pressed further southward into Byzantium), and weakening the
Saljuq Turks in Anatolia. The decline in Saljuq power enabled a rival group, the
Ottoman (or Osmanli) Turks, to rise against them. The Ottomans had settled in
northwestern Anatolia in the thirteenth century, under their leader Osman, as a
semi-independent client nation under Saljuq control, but they quickly emerged as
an autonomous power when Saljuq authority disintegrated. Keeping their main
power base in western Anatolia, the Ottomans created a tightly organized army
that in 1354 crossed the Bosporus and entered southeastern Europe to establish
the first Islamic beachhead in Christendom since the conquest of Spain in 711. The
Bulgars and Serbs, though no friends of the Byzantine state, rushed to the defense
of the Orthodox faith. They were defeated in a quick series of clashes, though, the
largest being the Turkish victory over the Serbs at the battle of Kosovo in 1389.
The Ottomans then established a Balkan capital at Adrianople [modern Edirne]
and proceeded thence to advance on Constantinople itself.
As Byzantium’s demise grew imminent, western Europe’s contacts with east-
ern Europe increased. It was clear, after all, that the empire had long served as a
buffer zone between the Christian world and the Islamic, between the European
and the Asian, and in its impending absence the states of eastern Europe would
become the buffer. Apart from Saxony and the East March territories of the
German empire, Latin Christendom had had little to do with eastern Europe ec-
onomically or culturally, but, starting in the fourteenth century and continuing
into the sixteenth, the importance of relations with the east grew dramatically.
Therefore, when Constantinople first appeared in serious danger of falling to the
Turks, the west responded, predictably, with yet another crusade. What was sur-
prising, though, was the degree to which the westerners put aside their own
squabbles in order to bring the crusade to pass. The English and French tempo-
rarily halted their Hundred Years War conflicts, the Burgundians joined in as well,
and even the two rival popes (one in Rome, the other in Avignon, as a result of
the Schism) set aside their differences. An army of about fifteen thousand soldiers,
made up roughly equally of French, Germans, and Burgundians agreed to serve
under the command of King Sigismund of Hungary, gathered near Budapest in
the summer of 1396 and began to march southeast against the Ottoman stronghold
of Nicopolis,

where they were joined by Venetian and Genoese auxiliaries. It took
some time for the sultan, Bayezid, to march up from Constantinople, but when he
arrived in September of that year he commanded a far superior force. What de-
cided the battle, however, was another outbreak of chivalry among the French
knights. They insisted on being placed in the front line so that they could lead the
charge uphill against an enemy whose tactics they knew nothing about. As had
happened to them as Cre´cy and Poitiers at the hands of the English, they were
cut down by volleys of Turkish arrows and their horses were impaled by networks
of spiked barricades. In the confusion that followed, Bayezid easily wiped out the
