Urartian, Vannic, and (in older literature) Chaldean (Khaldian, or Haldian) are conventional names for the language spoken by the inhabitants of the ancient kingdom of Urartu that was located in the region of Lake Van, with its capital near the site of the modern town of Van, in the Armenian Highland, modern-day Eastern Anatolia region of Turkey. It was probably spoken by the majority of the population around Lake Van and in the areas along the upper Zab valley.

First attested in the 9th century BCE, Urartian ceased to be written after the fall of the Urartian state in 585 BCE, and presumably it became extinct due to the fall of Urartu. It must have been replaced by an early form of Armenian, perhaps during the period of Achaemenid Persian rule, although it is only in the fifth century CE that the first written examples of Armenian appear.

Urartian was an ergative, agglutinative language, which belongs to neither the Semitic nor the Indo-European families but to the Hurro-Urartian family (whose only other known member is Hurrian). It survives in many inscriptions found in the area of the Urartu kingdom, written in the Assyrian cuneiform script. There have been claims of a separate autochthonous script of "Urartian hieroglyphs" but these remain unsubstantiated.

İshak Pasha (? - 1497, Thessaloniki) was an ethnic Serb who became an Ottoman general, statesman and later Grand Vizier.

His first term as a grand vizier was during the reign of Mehmet II (the conqueror). During this term he transferred Turkmen people from their Anatolian city of Aksaray to newly conquered İstanbul, to populate the city which had lost a portion of its former population prior to conquest. The quarter of the city where the Aksaray migrants had settled is now called Aksaray. His second term was during the reign of Beyazıt II.

Ishak Pasha is referenced in the 2011 video game Assassin's Creed: Revelations, as the leader of the Assassin Brotherhood in the Ottoman Empire. Ishak Pasha's armor was hidden underneath the Hagia Sophia, and was later recovered by the protagonist Ezio Auditore da Firenze.
