Mature Harappan urban civilization flourishes

Original prompt & settings (JSON) ↗There is no event here. 2300 BCE is a marker inside a centuries-long urban phase whose script remains undeciphered, so no readable inscription presently identifies a king, dynasty or capital.
A date with no event behind it
No discrete event is known for 2300 BCE. The date is a representative point inside the archaeologically defined Mature Harappan urban phase, conventionally about 2600 to 1900 BCE.
Nothing is known to have changed on any particular day or year. Cities and regional networks simply went on operating.
What was operating
Large centers including Harappa and Mohenjo-daro belonged to a wider network of cities, towns and rural settlements across modern Pakistan and western India — more than 1,000 known Harappan sites, by UNESCO's count.
These communities used writing, standardized weights and measures, specialized crafts, agriculture, water transport and long-distance trade. At Dholavira in Gujarat, inhabitants kept a fortified planned city with reservoirs, drainage and workshops, capturing scarce water from two seasonal streams.
Written everywhere, legible nowhere
Mesopotamian texts and archaeological finds record exchange with a region called Meluhha, generally identified with the Greater Indus region, attested from roughly 2400 to 2000 BCE. Around 2300 BCE a Mesopotamian seal could identify its owner as an interpreter of the Meluhhan language.
The Indus script itself remains undeciphered. It appears on seals and other objects but yields no rulers, state names, wars or decrees, and no readable royal inscription identifies a king, a dynasty or a capital.
Shared bricks, weights and seals across an enormous area do not by themselves prove one monarch or one capital. Nor does the decline belong here: the mature urban phase conventionally continued until about 1900 BCE.

Date corrected. The research places this at ~-2300.
What the sources leave uncertain
- The archaeological phase is well established, but 2300 BCE is only an approximate illustrative date.
- The undeciphered script prevents identification of rulers, state names, wars, decrees, or a year-by-year narrative.
- Population figures for individual cities and the civilization as a whole are model-based estimates, not contemporary counts.
- The Greater Indus cultural sphere should not automatically be treated as one territorially unified empire.
