2025-09-27 12:00 - 13:00
Charles Hamilton Houston, Thurgood Marshall and other great civil rights attorneys believed the fight for civil and equal rights should take place in the courts.
This presentation by Kathy Trusty of the Delaware Humanities will discuss their most famous case: Brown v Board of Education. Audiences will learn more about the lawyers behind the case and their strategy for proving that separate but equal, when it comes to race segregation, was not constitutional.
This presentation will also examine the five cases that made up Brown v Board of Education. It will delve into the actions and circumstances that led to each case and how five cases from around the country became one of the most important cases in the 20th century and resulted in a United States Supreme Court Ruling to end racial segregation in public schools.
This program has been made possible by Delaware Humanities, a state affiliate of the National Endowment for the Humanities.

In Common Cause: Delaware's Homefront in the Revolutionary War
2026-01-10 12:00 - 13:00
Despite its small size, Delaware made significant contributions to the cause of American independence—far more than a single battle or a midnight ride. During the Revolutionary War, Delaware evolved from being part of a larger colony into an independent state, a transformation driven by the sacrifices and efforts of its citizens and civic leaders. These individuals gave their time, resources, and even their personal safety to support the common cause of American freedom.
Join us as we explore the challenges faced and contributions made by the men and women of Revolutionary Delaware, preserved in the records of the Delaware Public Archives.

Women Scorned: Petit Reason and Punishment in 18th Century Delaware
2026-03-13 12:00 - 13:00
When Delaware declared its independence in 1776, it prompted a plethora of changes pertaining to its government and legal system. As the state grew and evolved, it reflected on crime and punishment in this new era. One crime that the new government reviewed was petit treason, which was treasonous acts committed against a person of authority other than the government.
Throughout its history, two Delaware women were tried for petit treason: Catherine Bevan in 1731 and Sarah Kirk in 1787. While their charges were the same, their punishments were not. Join us as we examine documents from the Delaware Public Archives’ collections to discuss these women and the changing legal system of a new Delaware.
