Seisachtheia

Seisachtheia (Greek: σεισάχθεια, from σείειν seiein, to shake, and ἄχθος achthos, burden, i.e. the relief of burdens) was a set of laws instituted by the Athenian lawmaker Solon (c. 638 BC–558 BC) in order to rectify the widespread serfdom and slavery that had run rampant in Athens by the 6th century BCE, by debt relief.
