  1. 01

    1,969 AD

    Apollo 11 astronauts become the first people to walk on the Moon.

    One small step, one permanent marker on the modern timeline.

    Neil Armstrong and Buzz Aldrin landed the lunar module Eagle in the Sea of Tranquility while Michael Collins remained in orbit. The mission turned a Cold War contest into one of the most widely shared scientific moments in human history.

  2. 02

    1,821 AD

    Revolts against Ottoman rule begin the Greek War of Independence.

    This question uses 1821 AD as its sourced chronological anchor.

    The conflict drew international support and eventually produced a recognized Greek kingdom.

  3. 03

    1,405 AD

    The first of Zheng He’s great Ming treasure fleets departs for the Indian Ocean.

    This question uses 1405 AD as its sourced chronological anchor.

    The expeditions projected imperial authority and linked Chinese ports with Southeast Asia, India, Arabia, and East Africa.

  4. 04

    1,753 BC

    The legal text now called the Code of Hammurabi is composed around this time.

    The stele presented royal justice as both public order and divine duty.

    The text is conventionally dated to about 1753 BCE and records judgments covering trade, property, family, labor, and injury. It was not the earliest law code, and historians debate whether it functioned as legislation, precedent, jurisprudence, or royal propaganda.

    Musée du Louvre · verified 2026-08-06

    The Louvre dates the stele to Hammurabi’s reign, 1792–1750 BCE; 1753 BCE is a conventional composition anchor within that range.

  5. 05

    2,600 BC

    Large planned cities begin flourishing across the mature Indus civilization.

    Urban order appeared in streets, drainage, weights, craft, and long-distance trade.

    Centers such as Harappa and Mohenjo-daro developed carefully planned neighborhoods and sophisticated water systems. The civilization used a still-undeciphered script and maintained wide trade connections.
