Sonoma is a historically significant city in Sonoma Valley, Sonoma County, California, United States, surrounding its historic town plaza, a remnant of the town's Mexican colonial past. Today, Sonoma is a center of the state's wine industry for the Sonoma Valley AVA Appellation, as well as the home of the Sonoma International Film Festival. Sonoma's population was 10,648 as of the 2010 census, while the Sonoma urban area had a population of 32,678.[10]



The area around what is now the City of Sonoma, California was not empty when the first Europeans arrived. It is near the northeast corner of the territory claimed by the Coast Miwok,[11] with Southern Pomo to the northwest, Wappo to the northeast, Suisunes and Patwin peoples to the east.[12][13]

Stylized portrayal of the Mission

Mission Period

Mission San Francisco Solano was the predecessor of the Pueblo of Sonoma. The Mission, established in 1823 by Father José Altimira of the Franciscan Order was the 21st, last and northernmost mission built in Alta California. It was the only mission built in Alta California after Mexico gained independence from the Spanish Empire.[14] In 1833 the Mexican Congress decided to close all of the missions in Alta California. The Spanish missionaries were to be replaced by parish priests.[15] The commander of the Company of the National Presidio at San Francisco (Compania de Presidio Nacional de San Francisco), Lieutenant Mariano Guadalupe Vallejo was appointed administrator (comisionado) to oversee the closing of Mission San Francisco Solano.[16] Governor José Figueroa's naming of Lieutenant Vallejo as the administrator to secularize the Mission was part of a larger plan.

Military - Rancho Period

Governor Figueroa had received instructions from the National Government to establish a strong presence in the region north of the San Francisco Bay to protect the area from encroachments of foreigners.[17] An immediate concern was further eastward movement of the Russian America Company from their settlements at Fort Ross and Bodega Bay on the California coast.[18]

Figueroa's next step in implementing his instructions was to name Lieutenant Vallejo as Military Commander of the Northern Frontier and to order the soldiers, arms and materiel at the Presidio of San Francisco moved to the site of the recently secularized Mission San Francisco Solano. The Sonoma Barracks were built to house the soldiers. Until the building was habitable the troops were housed in the buildings of the old Mission.[19]

The Governor granted Lieutenant Vallejo the initial lands (approximately 44,000 acres (178 km2)) of Rancho Petaluma immediately west of Sonoma. Vallejo was also named Director or Colonization which meant that he could initiate land grants for other colonists (subject to the approval of the governor) and the diputación (Alta California's legislature).[20]

Vallejo had also been instructed by Governor Figueroa to establish a pueblo at the site of the old Mission. In 1835, with the assistance of William A. Richardson he laid out, in accordance with the Spanish Laws of the Indies, the streets, lots, central plaza and broad main avenue of the new Pueblo de Sonoma.[21]

Although Sonoma had been founded as a pueblo in 1835, it remained under military control, lacking the political structures of municipal self-government of other Alta California pueblos. In 1843, Lieutenant Colonel Vallejo wrote to the Governor recommending that a civil government be organized for Sonoma. A town council (ayuntamiento) was established in 1844 and Jacob P. Leese was named first alcalde and Cayetano Juarez second alcalde.[22]

Bear Flag Revolt

John C. Frémont

Before dawn on Sunday, June 14, 1846, thirty-three Americans, already in rebellion against the Alta California government, arrived in Sonoma. Some of the group had traveled from the camp of U.S. Army Brevet Captain John C. Frémont who had entered California in late 1845 with his exploration and mapping expedition. Others had joined along the way. Since arriving in California the immigrants had not been allowed to buy or rent land and had been threatened with expulsion because they had entered without official permission.[23][24] Mexican officials were concerned about the coming war with the United States coupled with the growing influx of American immigrants into California.[25]

A group of rebellious Americans had departed from Frémont camp on June 10 and captured a herd of 170 Mexican government-owned horses being moved by Californio soldiers from San Rafael and Sonoma to Alta California's Commandante General José Castro in Santa Clara.[26] The insurgents next determined to seize the weapons and materiel stored in the Sonoma Barracks and to deny Sonoma to the Californios as a rallying point north of San Francisco Bay.[27]

Meeting no resistance, they approached Comandante Vallejo's home and pounded on his door. After a few minutes Vallejo opened the door dressed in his Mexican Army uniform. [28] Vallejo invited the filibusters' leaders into his home to negotiate terms. However, when the agreement was presented to those outside they refused to endorse it. Rather than releasing the Mexican officers under parole they insisted they be held as hostages. William Ide gave an impassioned speech urging the rebels to stay in Sonoma and start a new republic.[29] Referring to the stolen horses Ide ended his oration with "Choose ye this day what you will be! We are robbers, or we must be conquerors!"[30] At that time, Vallejo and his three associates were placed on horseback and taken to Frémont accompanied by eight or nine of the insurgents who did not favor forming a new republic under the circumstances.[31]

Bear Flag

The Sonoma Barracks became the headquarters for the remaining twenty-four rebels, who within a few days created their Bear Flag. After the flag was raised Californios called the insurgents Los Osos (The Bears) because of their flag and in derision of their often scruffy appearance. The rebels embraced the expression, and their uprising became known as the Bear Flag Revolt.[32]

There were some small unit skirmishes between the Bears and the Californios but no major confrontations. Hearing reports that Mexican General José Castro was preparing to attack, Frémont left his camp near Sutter's Fort for Sonoma on June 23. With him were ninety men - his own party plus some trappers and settlers.[33][34]

On July 5, Frémont called a public meeting and proposed to the Bears that they unite with his party and form a single military unit. He said that he would accept command if they would pledge obedience, proceed honorably, and not violate the chastity of women. A compact was drawn up which all volunteers of the California Battalion signed or made their marks.[35] The next day Frémont, leaving the fifty men of Company B at the Barracks to defend Sonoma, left with the rest of the Battalion for Sutter's Fort. They took with them two of the captured Mexican field pieces, as well as muskets, a supply of ammunition, blankets, horses, and cattle.[36]

War against Mexico had already been declared by the United States Congress on May 13, 1846.[37] Because of the slow cross-continent communication of the time, no one in California knew that conclusively. Commodore John D. Sloat, commanding the U.S. Navy's Pacific Squadron, had learned of Frémont's support for the Bears in Sonoma. Sloat finally concluded on July 6 that he needed to act, "I shall be blamed for doing too little or too much - I prefer the latter.[38] Early July 7, the United States Navy, captured Monterey, California, and raised the flag of the United States. Sloat had his proclamation read and posted in English and Spanish: "...henceforth California will be a portion of the United States."[39]

The Bear Flag Revolt and whatever remained of the "California Republic" ceased to exist on July 9 when U.S. Navy Lieutenant Joseph Revere raised the United States flag in front of the Sonoma Barracks and sent a second flag to be raised at Sutter's Fort.[40]

Early American period

28 star US flag

Until May 26, 1848, when Mexico and the United States ratified the Treaty of Guadalupe Hidalgo, Alta California was officially militarily-occupied enemy territory. Until a civilian authority was established the military decided to retain the Mexican administrative and judicial system of prefects for districts and alcaldes for municipalities.[41] This continued even after California became part of the United States because Congress never did organize California as a U. S. territory. California remained a military district so the old Mexican laws, supplemented by pronouncements of the military governors, largely remained in place. California finally did achieve statehood on September 9, 1850, as part of the slavery-focused Compromise of 1850.

Sonoma Barracks

Sonoma Barracks

Company B of the California Battalion, that had been left in Sonoma for the protection of the town, was soon placed under U.S. Navy command.[42] The American immigrants who comprised Company B eventually returned to their homes. Sonoma's Alcalde complained to the U.S. Navy about the lack of protection for the town and a detachment of U.S. Marines was assigned to the Sonoma Barracks.[43] In March, 1847, the Marines were replaced by Company "C" of what was called Stevenson's New York Volunteers.[44] The enlistments of the New York Volunteers ended with the war and they were replaced in May, 1849, by a 37-man company of U.S. dragoons (Company C, 1st U.S. Dragoons) who moved into the Barracks and established Camp Sonoma.[45] Sonoma was also the headquarters of the Pacific Division of the U.S. Army under Brevet Major General Persifor Smith. Sonoma lost its military population in January, 1852, when the troops moved to Benicia and other assignments in California and Oregon.[46] The Army continued to use part of the Barracks as a supply depot until August 1853.[47]

Sonoma's economic activity

Local businesses prospered with the business brought by the soldiers as well as miners traveling to and from the gold fields. The prosperity and optimism about Sonoma's future promoted land speculation which was particularly problematic because of the cloudy records regarding land ownership. Vallejo had granted land by virtue of his office as Director of Colonization before the pueblo was organized. Among the traditional duties of Alta California's alcaldes was the selling of town lots. Political factions backed different Sonoma alcaldes (John H. Nash, supported by the American immigrants, and Lilburn Boggs supported by Vallejo and the Californios) made the situation more complex.[48] Some property was sold more than once.[49] A valid land sale depended on proof of the seller's chain of title. Over thirty years of lawsuits were required before land owners in Sonoma were able to obtain clear titles.[50]

Statehood and loss of the county seat

California elected a civilian government (albeit by military order)[51] to organize the state before it was officially formed by the United States Congress in 1850. Sonoma was named the county seat for Sonoma County. About that time the flow of miners had slowed and the U.S. Army was leaving Sonoma. Business in Sonoma moved into a recession in 1851.[52] Surrounding towns such as Petaluma and Santa Rosa were developing and gaining population faster than Sonoma. An 1854 special election moved the county seat and its entailed economic activity to Santa Rosa.

Other History


Sonoma City Hall in the town plaza

El Pueblo de Sonoma was laid out in the standard form of a Mexican town, centered around the largest plaza in California, 8 acres (32,000 m2) in size. This plaza is surrounded by many historical buildings, including the Mission San Francisco Solano, Captain Salvador Vallejo's Casa Grande, the Presidio of Sonoma, the Blue Wing Inn, the Sebastiani Theatre, and the Toscano Hotel. In the middle of the plaza, Sonoma's early 20th-century city hall, at the plaza's center and still in use, was designed and built with four identical sides in order not to offend the merchants on any one side of the plaza. The plaza is a National Historic Landmark and still serves as the town's focal point, hosting many community festivals and drawing tourists all year round. There are approximately thirty restaurants in the plaza area, including Italian, Irish, Mexican, Portuguese, Basque, Mediterranean, Himalayan, and French. It provides a central tourist attraction. It is also the location of the Farmer's Market, held every Tuesday evening from April to October. In 2015, the town was named a Preserve America Community.[53]

20th century

The United States Navy operated a rest center at the Mission Inn through World War II.[54]


Sonoma is also considered the birthplace of wine-making in California, dating back to the original vineyards of Mission San Francisco Solano, with improvements made by Agoston Haraszthy, the father of California viticulture and credited with introduction of the Zinfandel/Primitivo grape varietal. The Valley of the Moon Vintage Festival takes place late each September, and is California's oldest celebration of its winemaking heritage. Many residents of Sonoma are third or fourth generation Italian-Americans, Portuguese-Americans, Spanish-Americans, and French-Americans, decedents of immigrants who came to the area to work in wine-making.


The city is situated in the Sonoma Valley, with the Mayacamas Mountains to the east and the Sonoma Mountains to the west, with the prominent landform Sears Point to the southwest.

The city has an area of 2.7 sq mi (7.0 km2), none of it covered by water.


Sonoma has typical Mediterranean weather with hot, dry summers (although nights are comfortably cool) and cool, wet winters. In February, the normal high is 58.4 °F (14.7 °C) and the typical low is 37.3 °F (2.9 °C). In July, the normal high is 89.8 °F (32.1 °C) and the normal low is 51.9 °F (11.1 °C). There are an average of 58.1 days with highs of 90 °F (32 °C) or higher and 12.1 days with highs of 100 °F (38 °C). The highest temperature on record was 116 °F (47 °C) on July 13, 1972, and the lowest temperature was 13 °F (−11 °C) on December 22, 1990. Normal annual precipitation is 30.64 inches (778 mm). The wettest month on record was 20.29 inches (515 mm) in January 1995. The greatest 24-hour rainfall was 6.75 inches (171 mm) on January 4, 1982. There are an average of 68.6 days with measurable precipitation. Snow has rarely fallen, but 1.0 inch fell in January 1907; more recently, snow flurries were observed on February 5, 1976 and in the winter of 2001.[55]

Environmental features

The principal watercourse in the town is Sonoma Creek, which flows in a southerly direction to discharge ultimately to the Napa Sonoma Marsh; Arroyo Seco Creek is a tributary to Schell Creek with a confluence in the eastern portion of the town. The active Rodgers Fault lies to the west of Sonoma Creek; however, risk of major damage is mitigated by the fact that most of the soils beneath the city consist of a slight alluvial terrace underlain by strongly cemented sedimentary and volcanic rock.[56] To the immediate south, west and east are deeper rich, alluvial soils that support valuable agricultural cultivation. The mountain block to the north rises to 1,200 feet (366 m) and provides an important scenic backdrop, around which views the city's original streetscape was carefully laid out.

In terms of fauna, there are a variety of birds, small mammals and amphibians which reside in Sonoma. California quail frequent the riparian areas, while black tailed deer kite, duck, swan, goose, towhee, waxwing, great blue heron, many egret, ibis and hawk, gull, tern, robin, thrush and sparrow species are found locally. Deer, mountain lions, and many small mammals are found locally as well.[citation needed]

The town of Sonoma boasts a relatively quiet setting, with California State Route 12 (called from north to south Sonoma Highway, West Napa Street, and Broadway), Fifth Street West, and Spain Street being the primary noise sources. About eight miles (13 km) south of the city is the Infineon Raceway, which is also a significant noise generator. The total citywide population exposed to environmental noise exceeding 60 CNEL is approximately 300.[citation needed]
