How did the slave economy develop in Athens?

During the era of Pericles, Athens’ slave economy also made great progress. During the reign of Pericles in the 5th century BC, it was the social and economic prosperity of this industrial and commercial city-state that entered a historical period of prosperity.

The handicraft industry developed rapidly, with many industries (there were more than twenty types in Athens at that time), fine division of labor, exquisite quality and dazzling products, and they were sold well overseas. Athens' commerce is also very developed, leaving merchants' footprints in many places along the Mediterranean and Black Sea coasts. The port of Piraeus has become an international commercial port, and the intermediary trade of import and export is very prosperous. Athens' shipbuilding industry was at a very high level and could manufacture merchant ships with a displacement of up to 250 tons. The warships it built were called "long-bodied ships" and could use 50 rowers. The commodity-currency relationship was fully developed, which was closely related to the external expansion of the Athenian state during this period. The victory against the Persian invaders promoted the development of this commodity-currency relationship to a considerable extent. The commodity-currency relationship also had an important impact on the democratic politics of Athens. This impact is reflected in the fact that the development of industry and commerce provided a certain source of livelihood for the poor classes among Athenian citizens, and the diversification of citizens' occupations and means of livelihood, It is conducive to maintaining the stability of the city-state and the Athenian democracy.
