Cuneiform scripts is the oldest written expression created by the Sumerians at 3000 BCE with some predecsessors reaching 4000 BCE.
Cuneiform was first developed by the ancient Sumerians of Mesopotamia c. 3500-3000 BCE.
In about 3000 BCE, their first city, Ur, was established. By about 2500 BCE they had established a ruling system that involved dynasties.
When the Sumerians first developed their script, it was read from top to bottom. Around 3000 BCE they began reading from left to right and their characters rotated 90 degrees counterclockwise.
The Sumerians invented the plow wheel in approximately 3500 BCE and bronze writing in about 4000 BCE. The Sumerians were the first to use bronze writing and not only invented the plow wheel but the plow as well.
The plough was invented by the Sumerians in Mesopotamia around 3000 BCE. This invention revolutionized agriculture by making it easier to till the soil and increase crop yields.
The concept of "years" to measure time began around 3000 BCE in ancient civilizations like the Sumerians and Egyptians.
The third millennium BCE spans from the year 3000 BCE to 2001 BCE. It marks a significant period in human history, characterized by the rise of early civilizations, advancements in agriculture, and the development of writing systems. This millennium includes notable cultures such as the Sumerians, Egyptians, and Indus Valley civilization.
The year 3000 BCE falls in the 30th century BCE, as the centuries are counted backward before the common era (CE). Each century consists of 100 years, so the 30th century BCE spans from 3100 BCE to 3001 BCE. Thus, 3000 BCE is the last year of the 30th century BCE.
