SACRAMENTO — Today, Governor Gavin Newsom and First Partner Jennifer Siebel Newsom announced the official launch of efforts to celebrate California’s 175th year of statehood. Today’s announcement initiates an effort to commemorate the rich and full history of the Golden State — its people, its progress, and its promise — and invites Californians across all regions and backgrounds to take part in honoring the milestone. This will include celebrations across the state, including on September 9, 2025 to mark 175 years since California joined the Union on September 9, 1850.
As part of the statewide commemoration, Governor Newsom and First Partner Siebel Newsom are launching a working group — supported by an Ambassador Circle of state and external leaders — to coordinate and amplify efforts that invite communities across the state to celebrate 175 years of growth, innovation, and diversity.
English version
“Throughout American history, California has been a beacon of innovation, shaping the very essence of the American Dream. The state has played a monumental role in igniting movements that have redefined industries, expanded rights, and shaped society. From the farmworker revolution that championed labor rights to the free speech movement that set new democratic standards, California has consistently been at the forefront of progress.”
Governor Gavin Newsom
“California has always been a place of possibility— a state where dreams are realized. Like our nation, our history is far from perfect, but it has been the people of California who have demanded the progress we celebrate today. Californians themselves are what make the Golden State so special, driving our culture, innovation, and resilience. As we celebrate this milestone, we honor the generations who have shaped California into what it is today so we may continue to work together to build a future where every Californian has the opportunity to thrive.”
First Partner Jennifer Siebel Newsom

California 175
As part of the State’s effort to commemorate California’s 175th Anniversary beginning September 9, 2025, Governor Newsom and First Partner Siebel Newsom are launching a working group – across state agencies and departments – to identify different ways people across the Golden State can mark the occasion and celebrate nearly two centuries of growth, innovation, and diversity. An ‘ambassador circle,’ composed of cabinet secretaries, legislative designees, constitutional officers and external partners, will help amplify and support activities throughout the state.
America 250
California’s celebration comes as the country gears up to celebrate 250 years next July. The working group will lead commemorations of both California 175 and America 250, with state agencies and departments celebrating efforts that reflect upon and honor the state’s and country’s history, building on that work to better our communities for the future.
