144 - 65 million years ago The Chatsworth Formation is created.

50,000 – 15,000 BC People of northeast Asia follow herds of caribou, bison & mammoth and migrate across the present day Bering Strait. They move south along ice-fee corridors into the North American continent to what is now California. Other people migrate north from what is now South America.

1200 -1800 AD Chumash cave dwellers paint pictographs in the caves of the Burro Flats.

1769 The Spanish claim Alta California (present day California) in the “Sacred Expedition,” when explorer Gaspar de Portolà reaches San Diego. With him are two Franciscan padres, Junipero Serra and Juan Crespi, who record the expedition and found the first mission. The Sacred Expedition is a religious & military project of missionization and colonization on behalf of Spain. Spanish citizenship is earned by Native Americans upon the acceptance of Christianity.

1797 Mission San Fernando Rey de España is created and housed on Rancho Encino. It is the 17th of the California missions established by Fray Fermin Francisco de Lasuen. Using Native American workers to not only construct the mission but also work it, the mission quickly becomes one of the most prosperous in California, producing abundant harvests and goods. The mix of agrarian and industrial life at this early stage in the Valley’s history sets a precedent for the future economy of the Valley as a pastoral region with some areas of industry.

1813 Father Muñoz and Father Nuez take the first census of the Valley which focused on Mission Indians.

1846 - 1848 The Mexican American War results in California becoming part of the United States, along with more than half of former Mexican land.

In 1915, the city of Los Angeles annexes the San Fernando Valley  - a crucial development as this enables the Valley to gain access to the water coming from Owens Valley from the Los Angeles Aqueduct (completed two years earlier under the direction of William Mulholland). The aqueduct provides a surplus of water to the city in anticipation of its future growth. Without this crucial aqueduct or annexation, the Valley would be vastly different. But the taking of this water destroys the environment and the economy of the Owens Valley, once a beautiful valley known for its migrating birds and diverse, self-sustaining ecosystems.

Celebrities and media promote Valley development. The Westerns “Bells of San Fernando” and  the Western “San Fernando Valley” are released.

1945 Despite the wartime ban against strikes, set designers from the Conference of Studio Unions strike against Warner Brothers film studio for 30 weeks. On October 5, also known as “Hollywood’s Black Friday,” picketing workers are attacked by executives and studio police, inciting “the Battle of Warner Brothers” at their Burbank studios. Producers pelt metal nuts and bolts from the roof and police hose workers and throw tear gas. Strikers overturn three cars in the melee. The strike ends and negotiations are never resolved. This bloody event leads to the passage of the 1947 Taft Hartley Act, which severely restricts workers’ abilities to strike and the power of unions.

Supposedly, this was the first time a nuclear reactor produces commercial electricity.

1959 Two events at the Santa Susana Research Facility disperse radioactivity. In March the AE-6 Reactor Accident releases contamination. In July the Sodium Reactor Experiment suffers a partial meltdown; its estimated release is 240 times that of 3 Mile Island. To the public, it is disclosed as a "parted fuel element" being observed. Official records state that 13 of 43 fuel elements suffered damage. Additional fuel-element handling accidents occurred during the recovery process that resulted in radiological releases to the environment and surrounding communities.

1992 The Rodney King trial takes place in Simi Valley with a jury of ten whites, one Latino, and one Asian. The jury acquits the officers. Upon hearing the verdict, hundreds of Los Angelenos begin a protest that turns into a “live” televised six-day riot where 53 people die and the total cost of damages equals $1,000,000,000.

1994 – 57 people lose their lives in the wake of the 6.7 magnitude Northridge Earthquake. With twenty billion dollars in damage, it is one of the costliest natural disasters in United States history.

2002 Measure F is designed to approve secession from Los Angeles. Although it initially gains momentum, the measure ultimately fails to garner enough votes.

Over 1,800,000 people live and work in the San Fernando Valley. If the 300 square mile area that is the Valley were a single city, it would be the 5th largest in the nation. Until now, there has been no one museum or institution to document, preserve, and celebrate the full scope of the collective history, culture, and arts of such an important place until the 2005 incorporation of The Museum of the San Fernando Valley.
