her forces were defeated. The son and his
mother were reconciled in 1622, with
Marie advancing her ally Cardinal Rich-
elieu to the position of the king’s chief
minister. Within a few years Richelieu and
Marie de’ Médicis were adversaries, with
the king eventually siding with Richelieu
and again banishing Marie. After she
mounted a foiled coup against the king,
she was exiled by the king, this time to the
city of Compiegne and then out of the
kingdom permanently. Marie fled to the
Netherlands, where she continued to rally
opponents of Richelieu in hopes of return-
ing to Paris in control of the royal court.
She failed, however, and lived a shadowy
life as an exile until her death in 1642.

Mehmed II .....................................
(1432–1481)
Sultan of the Ottoman Empire, and con-
queror of Constantinople and the Eastern
Roman or Byzantine Empire. Born in the
Ottoman capital of Edirne, Mehmed II was
the son of Sultan Murad II. He was trained
as a ruler in the province of Amasya, and
at the age of twelve became the titular Ot-
toman ruler after his father abdicated his
throne. Hard-pressed to rally troops be-
hind him for an assault against Christians
in the Balkans, Mehmed ordered his father
out of retirement to lead the Turks in the
Battle of Varna in 1444, a complete victory
for the Ottoman forces. In 1451 Murad II
died and Mehmed became the unques-
tioned leader of the empire. Over the next
two years, he rallied his forces for an as-
sault on Constantinople, defended by a
stout ring of fortifications. The siege of
Constantinople ended in May 1453, with
the fall of the city and the death of the
last Byzantine emperor, Constantine XI.
After this victory, Mehmed was able to
extend his authority throughout Anatolia
and use Constantinople as a base for fur-
ther assaults against Christian states in the
Balkan Peninsula. Mehmed besieged Bel-
grade in 1456 and in the following years
battled an army led by Prince Vlad Dracula
of Wallachia. Mehmed seized the last rem-
nants of the Byzantine Empire in the
Peloponnesus in 1460 and Trebizond, in
Anatolia, in 1461.
Mehmed allowed Byzantine Christians
to remain in Constantinople and freely
practice their faith. He attempted to forge
cultural links with European nations, in-
viting artists and scholars to work under
his patronage. He improved roads and ca-
nals in his newly conquered capital and
also raised important structures, including
the Topkapi Palace, which remained the
home of the sultans throughout Ottoman
history. Mehmed’s personal ambitions
were unsatisfied by the fall of Constanti-
nople, however. He attacked the Italian
peninsula in 1480, intending to besiege
Rome and become the ruler of a reunited
Roman Empire. Although he captured the
southern Italian port of Otranto, his lines
of retreat were threatened by a rebellion in
Albania and, under pressure from a Chris-
tian army gathered by Pope Sixtus IV, he
retreated from Italy in 1481.

Melanchthon, Philipp ......................
German theologian, ally of Martin Luther,
and early leader of the Protestant Refor-
mation in Germany. Born in the town of
Bretten in the Palatine, Melanchthon stud-
ied the Latin and Greek classics and, at the
age of thirteen, was admitted to the Uni-
versity of Heidelberg. Too young to earn a
degree, he moved to the University of Tub-
ingen in 1512, and took up the study of
