Recent findings (audit lane, verbatim)

Istanbul — The Ottoman Empire did not officially adopt the title of caliphate until 1517, not immediately after the conquest of Constantinople in 1453.

Varanasi — The Lion capital of Ashoka at Sarnath was erected in the 3rd century BCE, not the 5th century BCE, so the phrasing linking it to the Buddha's first sermon in the 5th century BCE is chronologically misleading.

Varanasi — Adi Shankara did not establish the worship of Shiva as an official sect in Varanasi; Shaivism was already prominent there long before the 8th century.

Baghdad — Baghdad became the capital of Mandatory Iraq during the First World War

Baghdad — The Round City of Baghdad took four years (764–768) to build

Isfahan — The claim that Isfahan is the 'second-largest metropolitan area' in Iran is factually incorrect; the second-largest metropolitan area in Iran is Mashhad, not Isfahan.

Isfahan — The statement that Isfahan 'flourished between the 9th and 18th centuries' is misleading; the 9th century was a period of decline after the Arab conquest, not a recognized peak period.

Cusco — The fortress Sacsayhuamán is stated to have been constructed in the 11th century, but archaeological evidence indicates construction began in the 15th century under Pachacuti.

Cusco — The city is said to have been founded in the 12th century by Manco Cápac, but traditional Inca history places the founding of Cusco around the 13th century (c. 1200 CE).

Luxor — The claim that Luxor Temple was never buried by sand is inaccurate; it was partially buried over centuries and was excavated in the modern era.

Luxor — The statement that the Valley of the Kings contains tombs of only New Kingdom pharaohs is misleading; while primarily New Kingdom, some tombs belong to nobles and non-royal individuals.

Babylon — The Old Babylonian Empire is dated 19th–16th century BC in the intro, but the standard dating is roughly 1894–1595 BC, making '19th century' too early.

Babylon — The claim that Hammurabi 'founded' the Old Babylonian Empire is inaccurate; it was founded by Sumu-abum, and Hammurabi expanded it into an empire.

Carthage — The claim that Carthage was taken by Crusaders during the Eighth Crusade and its inhabitants massacred is incorrect.

Carthage — The statement that the Hafsids destroyed Carthage's defenses after it was taken by Crusaders is inaccurate because Carthage was not taken by Crusaders in the Eighth Crusade.
