The outline of the history as gathered from Hammer and D'Ohsson is as
follows:--

NOGHAI, for more than half a century one of the most influential of the
Mongol Princes, was a great-great-grandson of Chinghiz, being the son of
Tatar, son of Tewal, son of Juji. He is first heard of as a leader under
Batu Khan in the great invasion of Europe (1241), and again in 1258 we
find him leading an invasion of Poland.

In the latter quarter of the century he had established himself as
practically independent, in the south of Russia. There is much about him
in the Byzantine history of Pachymeres; Michael Palaeologus sought his
alliance against the Bulgarians (of the south), and gave him his
illegitimate daughter Euphrosyne to wife. Some years later Noghai gave a
daughter of his own in marriage to Feodor Rostislawitz, Prince of
Smolensk.

Mangu- or Mangku-Temur, the great-nephew and successor of Barka, died in
1280-81 leaving nine sons, but was succeeded by his brother TUDAI-MANGKU
(Polo's _Totamangu_). This Prince occupied himself chiefly with the
company of Mahomedan theologians and was averse to the cares of
government. In 1287 he abdicated, and was replaced by TULABUGHA
(_Tolobuga_), the son of an elder brother, whose power, however, was
shared by other princes. Tulabugha quarrelled with old Noghai and was
preparing to attack him. Noghai however persuaded him to come to an
interview, and at this Tulabugha was put to death. TOKTAI, one of the sons
of Mangku-Temur, who was associated with Noghai, obtained the throne of
Kipchak. This was in 1291. We hear nothing of sons of Tudai-Mangku or
Tulabugha.

Some years later we hear of a symbolic declaration of war sent by Toktai
to Noghai, and then of a great battle between them near the banks of the
Don, in which Toktai is defeated. Later, they are again at war, and
somewhere south of the Dnieper Noghai is beaten. As he was escaping with a
few mounted followers, he was cut down by a Russian horseman. "I am
Noghai," said the old warrior, "take me to Toktai." The Russian took the
bridle to lead him to the camp, but by the way the old chief expired. The
horseman carried his head to the Khan; its heavy grey eyebrows, we are
told, hung over and hid the eyes. Toktai asked the Russian how he knew the
head to be that of Noghai. "He told me so himself," said the man. And so
he was ordered to execution for having presumed to slay a great Prince
without orders. How l
