DAR Chapter Meeting – “The American Revolution & The Fate of the World”
March 10, 2026 at 7:30 p.m.

Belair Mansion
12207 Tulip Grove Drive
Bowie, MD

Speaker: Dr. Richard Bell, University of Maryland history professor
Topic: The American Revolution & The Fate of the World 

In this book talk, award-winning historian Richard Bell reveals the full breadth and depth of America’s founding fight. The American Revolution was not only the colonies’ triumphant liberation from the rule of an overbearing England; it was also a cataclysm that pulled in participants from around the globe and threw the entire world order into chaos. Repositioning the Revolution at the center of an international web, Bell ranges as far afield as India, Africa, Central America, and Australia. As his lens widens, the “War of Independence” manifests itself as a sprawling struggle that upended the lives of millions of people on every continent and fundamentally transformed the way the world works, disrupting trade, restructuring penal systems, stirring famine, and creating the first global refugee crisis. Bell conveys the impact of these developments at home and abroad by grounding this story in the gripping stories of individuals—including women, minorities, and other disenfranchised people. The result is an unforgettable and unexpected new vista on American history that shifts everything we thought we knew about our creation story.

Belair Mansion
12207 Tulip Grove Drive
Bowie, MD

Speaker: Lauren Silberman, local author
Topic: Wild Women of Maryland: Grit and Gumption in the Free State 

The daring women of Maryland made their mark on history as spies, would-be queens, and fiery suffragettes. Sarah Wilson escaped indentured servitude in Frederick by impersonating the queen’s sister. In Cumberland, Sallie Pollock smuggled letters for top Confederate officials. Baltimore journalist Marguerite Harrison snuck into Russia to report conditions there after World War I. From famous figures like Harriet Tubman to unsung heroines like “Lady Law” Violet Hill Whyte, author Lauren R. Silberman introduces Maryland’s most tenacious and adventurous women. 

Book Talk with Zaakir Tameez on Charles Summer: Conscience of a Nation
April 16, 2026 from 6:30 p.m. – 8:00 p.m.

A virtual talk presented by author historian Zaakir Tameez. This outstanding book is about the courageous Massachusetts senator Charles Sumner who is remembered for receiving a physical beating while serving in Congress and for his leadership during and after the U.S. Civil War for civil rights. Drawing from hundreds of letters, newspapers, and speeches, Mr. Tameez has created a remarkable portrait of a complex man who faced many personal challenges. Charles Sumner is a moving portrayal of a courageous, long-overlooked American who, in the words of one contemporary, “stood in the vanguard of freedom.”
