About 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, and we write new articles (and update old ones) every day. All the articles are written by historians with advanced degrees; the site is run by Dr. Karen Carr.

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.

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 Americans, Christians, the rich, the able-bodied, and the heterosexual. We're aiming to tell the stories of women, people of color, Buddhists and Muslims, the poor, gay 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, which have their own history that often intersects human history.

Quatr.us tries to tell the history of all people, not just rich and powerful people. So even though we do have pages on the Emperor Claudius and on Queen Elizabeth, you won't find full biographies of powerful people here. Instead, we have many pages about the history of food, climate and environmental change, scientific 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 it on all our pages). Most pages also have a link to suggested projects that will help you understand the concepts you've learned.

Quatr.us has been free and available to anyone with an Internet connection for twenty years, but that doesn't come cheap! Please help us keep the lights on by donating here, sponsoring a page, or buying a year-long subscription (which also blocks the ads).
