Welcome to Quatr.us!

Quatr.us is a study guide for anybody interested in history. There is currently no printed version. We’ve been online since 1995. We write new articles (and update old ones) every day. Historians with advanced degrees write all our articles.

Who we are

Professor Carr holds a BA with high honors in Classics and Archaeology from Cornell University, and a PhD in Classical Art and Archaeology from the University of Michigan, Ann Arbor. She is an Associate Professor Emerita of History at Portland State University.

What we do

Quatr.us aims to present history for the 21st century. Like other historians today, we work towards reducing the traditional over-representation of men, Europeans and white AmericansChristians, the rich, the able-bodied, and the heterosexual. We’re aiming to tell the stories of womenpeople of colorBuddhists and Muslims, the poorgay people, and other traditionally marginalized or under-represented people. We also want to include the history of the planet and its rocks and animals and plants. They have their own history that often intersects human history.

Resources and projects

Quatr.us tries to tell the history of all people, not just rich and powerful people. We do have pages on the Emperor Claudius and on Queen Elizabeth. But you won’t find full biographies of powerful people here.

Instead, we have many pages about the history of foodclimate and environmental changescientific discoveries and inventions, the history of medicine, the history of games, famous playwrights and poets, and the kind of clothing people wore. Finally, Quatr.us also has bibliography and suggestions for further reading on most pages. (We’re working to have bibliographies on all our pages.) Most pages also have a link to suggested projects. They will help you understand the concepts you’ve learned.
