The New York Times 1619 Project is reshaping the conversation on slavery. Conservatives hate it.

On Sunday, the New York Times Magazine published perhaps its most ambitious work on race and slavery to date. The 1619 Project, which marks the 400th anniversary of the arrival of African slaves to Virginia, seeks to reframe the country’s thinking about slavery and how intertwined the practice of slavery has been in shaping the nation.

“This project is, above all, an attempt to set the record straight. To finally, in this 400th year, tell the truth about who we are as a people and who we are as a nation,” New York Times Magazine reporter Nikole Hannah-Jones said during a launch event for the series. The project, which is also online, so far features over a dozen reported essays, photo essays, and poems by black writers, artists, scholars, with more to come.
