“There’s only the American Dream and the California dream.”
—Gov. Gavin Newsom

This year marks the 175th anniversary of California’s admission to the U.S. as the 31st state. But statehood wasn’t the beginning of the story. Celebrating California is a collection of 175 stories that highlight California’s unique history and role in the world. The goal is to offer examples of California’s unique character and that of its residents, past and present. That means among the good there will be some bad. For every success story, there’s a failure, a tragedy, an injustice. It’s from these mistakes that we learn and grow stronger together. Share a story with us that helps define what California means to you.
