The Attic-Euboean standard, also known as the Euboic-Attic standard, became very widespread due to several key factors:

1. Greek Colonisation: Euboea's significant role in Greek colonisation during the Archaic period facilitated the spread of this standard in the Greek West and the Pontic regions. As Greek colonies were established, they carried with them the weight and monetary systems of their mother cities, which included the Attic-Euboean standard (Wikipedia).

2. Athenian Empire: The ascendancy of the Athenian empire, particularly in the 5th century BC, contributed significantly to the widespread adoption of this standard. Athens, being a major economic and military power, influenced many other city-states to adopt its standards for trade and commerce (Britannica).

3. Commercial Interests: The spread of Greek influence through commercial activities played a crucial role. Markets and trade routes were standardized to facilitate easier and more efficient trade. The adoption of uniform standards like Attic-Euboean helped streamline transactions across different regions (Britannica).

4. Aligning Smaller City-States: Many smaller city-states aligned themselves with the prosperous Athens and adopted the Attic/Euboean standard to benefit from its economic clout. This alignment not only facilitated trade but also brought smaller states under the economic and cultural influence of Athens (ResearchGate).

5. Cultural Exchange: Due to its widespread use in urban centers, the Euboic-Attic standard facilitated extensive cultural exchanges, which also influenced art, philosophy, and daily life in ancient Greece (Fiveable).

These factors collectively contributed to the widespread adoption and influence of the Attic-Euboean standard across the ancient Greek world.
