This Major League Soccer rivalry reached its zenith from 2001 to 2005, during which time the Earthquakes and the Galaxy combined to win four MLS Cup titles.
The term "Clasico" is commonly used to refer to other rivalries in Spanish-speaking countries, most prominently, the Spanish Clásico between Barcelona and Real Madrid, or the Argentine Superclásico between Boca Juniors and River Plate.
In 2001, both teams reached the MLS Cup 2001, with San Jose posting a 2–1 overtime victory on goals by Landon Donovan and Dwayne DeRosario.
While next season, Carlos Ruiz led Los Angeles to its first MLS Cup title over the New England Revolution after San Jose was previously upset in the playoffs by the Columbus Crew.
While there have been several players to play for both teams beforehand, the rivalry intensified after the Anschutz Entertainment Group (owner of the Los Angeles Galaxy) took sole ownership of the San Jose Earthquakes in December 2002.
After eliminating the Galaxy, San Jose went on to defeat the Kansas City Wizards en route to winning its second MLS Cup title (over the Chicago Fire) in three years.
After a rumored buyout of the Quakes by Mexican soccer side Club América in January 2004, Earthquakes general manager Johnny Moore resigned prior to the 2004 season and was replaced by former U.S. and Galaxy defender Alexi Lalas.
"[8] Following the departure of Lalas to become the general manager of the MetroStars early in 2005, San Jose returned to form and captured the MLS Supporters' Shield, awarded to the league's best team during the regular season.
Meanwhile, shortly after Lalas' brief stint with the MetroStars, he moved on to become the general manager of the Galaxy, who failed to make the playoffs during both years of San Jose's hiatus from the league.
In June 2013, the Clásico returned to Stanford Stadium and in stunning comeback fashion, the Earthquakes defeated the Galaxy with two goals by Shea Salinas and Alan Gordon in stoppage time (92',93') to win the game 3–2.
San Jose became the first MLS team ever to win a game in extra time with 10 men after Víctor Bernárdez was red carded in the 77' minute.
[17] The third official Clásico was fought just a week later on July 10, when San Jose and Los Angeles met again at Avaya Stadium, this time in the quarterfinals of the U.S. Open Cup.
LA captain van Damme once again opened the scoring off of a corner kick, and once again San Jose came back to win, this time 3–2, on a Chris Wondolowski brace assisted entirely by Tommy Thompson and Hoesen's winner scored on a counter launched by Jahmir Hyka, with LA's second tally coming after an own goal that deflected off the back of San Jose keeper Andrew Tarbell.
Due to the relative proximity of the cities, which are about 360 miles (580 km) apart, charter buses and shuttle vans are used to allow rival fans to attend each other's games.
On October 21, 2012 during a regular season game at Buck Shaw Stadium, several LA Galaxy fans were arrested after violent altercations erupted in the stands and smoke bombs were set off during half time.
On October 13, 2013, the California Clasico was highlighted on the TV series, MLS Insider, explaining the history of the rivalry from the different perspectives of players such as Chris Wondolowski and Landon Donovan.
