Who was the first Democratic governor of Illinois since 1850 and advocated for progressive reforms?

John Peter Altgeld was indeed the first Democratic governor of Illinois since 1850 and is known for his advocacy of progressive reforms. During his time in office from 1893 to 1897, he implemented significant changes that reflected a more modern, progressive platform aimed at improving the lives of working-class citizens. His administration focused on issues such as labor rights, social justice, and prison reform, marking a notable shift in Illinois' political landscape after decades of Republican dominance.

Altgeld is particularly recognized for his response to labor unrest, especially the Pullman Strike of 1894, where he spoke out against federal intervention and supported the rights of workers. He also championed reforms in the criminal justice system, including measures intended to reduce the harshness of sentences and improve prison conditions. His governance set the stage for the more comprehensive progressive movements that would gain momentum in the early 20th century.
