Likewise, no instruments of peace are known to have been issued by
Vladislaus IV, with one notable exception. Although the king obtained
several ‘ahdnames from the khans Djanibek Giray (1634), Inayet Giray
(1635), Bahadır Giray (1637 and 1640), and Islam III Giray (1646),
and, in addition, two ‘ahdnames from the qalga (1637 and 1640) and
one from the nureddin (1640), he only once responded with an analo-
gous instrument, namely in 1637. While sending a letter of agreement
(list przymierny) to Qalga Islam Giray, Vladislaus IV simultaneously
procrastinated his answer to the khan and even detained the latter’s
envoy. By keeping good relations with the qalga, the king tried to gain
time before he could decide whether to send gis to the khan or pre-
pare for a military confrontation. In fact, during the last years of his
reign, Vladislaus contemplated a full-scale invasion of the Crimea, to
be orchestrated by Warsaw and Moscow and subsidized by Venice.
It was the political and military catastrophe of the years 1648–1649
that prompted the Polish king to issue an instrument of peace addressed
to the Crimean khan, probably for the rst time since 1605. In August
1649, in a military camp near Zboriv, John Casimir, Vladislaus’ brother
and successor, issued a document that contained the peace conditions
negotiated between the Polish and Tatar plenipotentiaries. e king
engaged to resume the payment of the customary gis to the khan and
to restore the ancient liberties to the Cossacks on the condition that
the latter would return under his rule. On his part, Islam III Giray was
to withdraw his troops from the royal lands while causing “the least
possible damage.” As the Polish Vasas still claimed hereditary rights to
the Swedish throne, the royal document was dated “in the rst year of
our reign in Poland and the second year [of our reign] in Sweden.”

e pacication of 1649 was soon followed by a new outbreak of
hostilities, but the next Polish-Tatar pacication, negotiated in 1653 at
Žvanec’, and especially the Cossacks’ entry under the tsar’s patronage,
conrmed in Perejaslav in January 1654, paved the way to a lasting
rapprochement between Warsaw and Baghchasaray. In July 1654, arti-
cles of peace and military alliance were negotiated in Warsaw between

See Document 59; John Casimir claimed hereditary rights to the Swedish throne
from the death of his older brother Vladislaus, i.e., from May 1648. As to the Polish
throne, his reign began with his election in November 1648, and formally even later,
with his coronation in January 1649. e two ocial copies of the royal instrument,
preserved in the Crown Archives, do not contain the locatio and datatio, which are
extant in other copies. e original document, corroborated by the king and sent to
the khan, must have also contained the royal seal.
