Summerian City Lagash instigated history's first recorded Tax revolt. This came after Lagash's rulers had increased local taxes and restricted personal freedoms. The people of Lagash resented this enough that they overthrew their King. They brought to power a god-fearing ruler named Urukagina, who eliminated excessive taxation and rid the city of usurers, thieves and murderers -- the first known reform . Time frame is stated for Urukagina (reigned ca. 2380 BC–2360 BC) However the dating process is in doubt as is all dating systems for ancient world.
