…this pressure is felt in Corinth's own backyard, at Megara.

Athens passes a series of measures (the “Megarian decrees”) imposing an economic embargo on Megara for violations of sacred land.

The religious aspect of the offense is reflected in the exclusions imposed: like murderers, the Megarians are banned from the Athenian marketplace and the harbors in the Athenian empire.

However, there is no doubt that Athens causes and intends to cause economic hardship as well or that the decrees are the first move in securing Megara as a military asset.
