Answer
Reformer best describes Solon's role. As an Athenian statesman and lawmaker in the 6th century BCE, Solon implemented significant reforms to address social and economic inequalities. He abolished debt slavery, introduced a new legal code, and established a system of property-based classes that granted political rights to all citizens. Solon's reforms aimed to create a more just and equitable society, earning him the title of "reformer."
