The Maya civilization began building its society around A.D. 250.
Notes on verification
The A.D. 250 date is well-corroborated as the conventional start of the Maya Classic Period across multiple scholarly and educational sources. However, the claim's phrasing 'began building its society' is misleading/imprecise, since Maya civilization, agriculture, and even large cities existed for over a millennium prior during the Preclassic period. Confidence reflects strong support for the date itself but ambiguity in the claim's wording.
