As of
182-529: A series of 21 religious outposts or missions established between 1769 and 1833 in what is now the U.S. state of California . The missions were established by Catholic priests of the Franciscan order to evangelize indigenous peoples backed by the military force of the Spanish Empire . The missions were part of the expansion and settlement of New Spain through the formation of Alta California , expanding
273-527: A "mother" mission. However, the plan's expansion never came to fruition. In addition to the presidio (royal fort) and pueblo (town), the misión was one of the three major agencies employed by the Spanish sovereign to extend its borders and consolidate its colonial territories. Asistencias ("satellite" or "sub" missions, sometimes referred to as "contributing chapels") were small-scale missions that regularly conducted Mass on days of obligation but lacked
364-463: A barred window. After the marriage ceremony the woman moved out of the mission compound and into one of the family huts. These "nunneries" were considered a necessity by the priests, who felt the women needed to be protected from the men, both Indian and de razón ("instructed men", i.e. Europeans). The cramped and unsanitary conditions the girls lived in contributed to the fast spread of disease and population decline . So many died at times that many of
455-744: A character actively sought by some housing purchasers. The downside of this is a corresponding lack of affordable housing for those working lower-paying service jobs — a problem endemic throughout the region. There has recently been a housing boom or tract housing in Richmond and also in the Hercules areas. These gentrifying areas are the most diverse in Contra Costa County. Spanish Missions of California The Spanish missions in California ( Spanish : Misiones españolas en California ) formed
546-442: A colony of any size. California was months away from the nearest base in colonized Mexico, and the cargo ships of the day were too small to carry more than a few months' rations in their holds. To sustain a mission, the padres required converted Native Americans , called neophytes , to cultivate crops and tend livestock in the volume needed to support a fair-sized establishment. The scarcity of imported materials, together with
637-424: A concrete-lined and fenced irrigation canal still makes a loop through central county and provided industrial and agricultural grade water to farms and industry. While no longer used for extensive irrigation, it is still possible for adjoining landowners (now large suburban lot owners) to obtain pumping permits. Most of this water is destined for the heavy industry near Martinez. As with the railroad rights of way there
728-481: A lack of skilled laborers, compelled the missionaries to employ simple building materials and methods in the construction of mission structures. Although the missions were considered temporary ventures by the Spanish hierarchy , the development of an individual settlement was not simply a matter of "priestly whim." The founding of a mission followed longstanding rules and procedures; the paperwork involved required months, sometimes years of correspondence, and demanded
819-507: A non-Indian population of over 100,000. The number of Indians living in California in 1850 has been estimated to be from 60,000 to 100,000. By 1850 the Mission Indian populations had largely succumbed to disease and abuse and only numbered a few thousand. California's 1852 state Census gives 31,266 Indian residents, but this is an under-count since there was little incentive and much difficulty in getting it more correct. Contra Costa County
910-504: A once substantial integrated steel plant, United States Steel , now reduced to secondary production of strip sheet and wire. The San Joaquin River forms a continuation of the northern boundary turns southward to form the eastern boundary of the county. Some substantial Sacramento-San Joaquin Delta "islands" (actually leveed former marshes) are included in this corner of the county. The West County
1001-488: A resident priest; as with the missions, these settlements were typically established in areas with high concentrations of potential native converts. The Spanish Californians had never strayed from the coast when establishing their settlements; Mission Nuestra Señora de la Soledad was located farthest inland, being only some thirty miles (48 kilometers) from the shore. Each frontier station was forced to be self-supporting, as existing means of supply were inadequate to maintain
SECTION 10
#17328480798051092-491: A scarcity of land for agriculture and potable water left the success of such a venture in doubt, so no effort to found an island mission was ever made. In September 1821, the Rev. Mariano Payeras, " Comisario Prefecto " of the California missions, visited Cañada de Santa Ysabel east of Mission San Diego de Alcalá as part of a plan to establish an entire chain of inland missions. The Santa Ysabel Asistencia had been founded in 1818 as
1183-473: A two-hour siesta , and ended with evening prayers and the rosary , supper, and social activities. About 90 days out of each year were designated as religious or civil holidays, free from manual labor . The labor organization of the missions resembled a slave plantation in many respects. Foreigners who visited the missions remarked at how the priests' control over the Indians appeared excessive, but necessary given

Contra Costa County's physical geography is dominated by the bayside alluvial plain, the Oakland Hills – Berkeley Hills , several inland valleys, and Mount Diablo , an isolated 3,849-foot (1,173 m) upthrust peak at the north end of the Diablo Range of hills. The summit of Mount Diablo is the origin of the Mount Diablo Meridian and Base Line , on which
1547-430: Is now Concord/Buchanan Field Airport . Additionally, a large Naval Weapons Depot and munitions ship loading facilities at Port Chicago remain active to this day, but with the inland storage facilities recently declared surplus, extensive redevelopment is being planned for this last large central-county tract. The loading docks were the site of a devastating explosion in 1944. Port Chicago was bought out and demolished by
1638-446: Is now an extensive public trail system along these canals. The development of commuter railroads proceeded together with the subdivision of farms into parcels. In some cases, such as the development of Saranap , the same developer controlled both the railroad ( Sacramento Northern ) and the development. These early suburbanization developments were an extension of the earlier development of trolley car suburbs in what are now considered
1729-416: Is the area near or on San Francisco and San Pablo bays. The housing stock in the region was extensively developed after the great San Francisco earthquake of 1906. Much of the housing stock in these areas is becoming quite expensive. As an alternative to moving to either the expensive central county, or the too-distant East County, this area is becoming gentrified , with a mix of races and income levels —
1820-526: The 2020 United States Census , the population was 1,165,927. The county seat is Martinez . It occupies the northern portion of the East Bay region of the San Francisco Bay Area and is primarily suburban . The county's name refers to its position on the other side of the bay from San Francisco . Contra Costa County is included in the San Francisco–Oakland–Berkeley, CA Metropolitan Statistical Area . In prehistoric times, particularly
1911-519: The Bay Area Rapid Transit (BART) system, the modernization of Highway 24 , and the addition of a fourth Caldecott Tunnel bore all served to reinforce the demographic and economic trends in the Diablo Valley area, with cities such as Walnut Creek and Concord becoming edge cities . The central county cities have in turn spawned their own suburbs within the county, extending east along

#17328480798052002-594: The Camino Real . The detailed planning and direction of the missions was to be carried out by Friar Junípero Serra , O.F.M. (who, in 1767, along with his fellow priests , had taken control over a group of missions in Baja California Peninsula previously administered by the Jesuits). After Serra's death, Rev. Fermín Francisco de Lasuén established nine more mission sites, from 1786 through 1798; others established
2093-462: The Diablo thrust fault near Danville are all considered capable of significantly destructive earthquakes and many lesser related faults are present in the area that cross critical infrastructure such as water, natural gas, and petroleum product pipelines, roads, highways, railroads, and BART rail transit. Contra Costa County is broadly divided into three sub-areas: The most notable natural landmark in
2184-625: The Mexican War of Independence resulted in the secularization of the missions with the re-distribution of their lands, and a new system of land grants under the Mexican Federal Law of 1824. Mission lands extended throughout the Bay Area, including portions of Contra Costa County. Between 1836 and 1846, during the era when California was a province of independent Mexico, the following 15 land grants were made in Contra Costa County. The smallest unit
2275-716: The Miocene epoch , portions of the landforms now in the area (then marshy and grassy savanna ) were populated by a wide range of now extinct mammals , known in modern times by the fossil remains excavated in the southern part of the county. In the northern part of the county, significant coal and sand deposits were formed in even earlier geologic eras . Other areas of the county have ridges exposing ancient but intact (not fossilized) seashells, embedded in sandstone layers alternating with limestone . Layers of volcanic ash ejected from geologically recent but now extinct volcanoes , compacted and now tilted by compressive forces, may be seen at
2366-597: The San Ramon Valley . Early contact was fleeting and mostly peaceful, however, in the late 1700s, Spanish cattle were grazed the territory of the Saklan and their neighbors. The Saklans were one of the few groups who mounted resistance against the efforts of the Spanish to convert them to Christianity. Christian natives were sent to the Saklans to convince them to give up their culture and come to Mission San Jose; they were killed by

The Calaveras Fault runs in the south-central portion of the county, from Alamo to San Ramon. The Concord Fault runs through part of Concord and Pacheco, and the Clayton-Marsh Creek-Greenville Fault runs from Clayton at its north end to near Livermore. These strike-slip faults and

Since 1932, Contra Costa County has been a Democratic stronghold in presidential elections. It temporarily leaned toward the Republican Party in the 1970s and 1980s, with successive presidential wins by Richard Nixon in 1972, Gerald Ford in 1976, and Ronald Reagan in 1980 and 1984. Reagan

The site of the former Atlas Powder Company is located at Point Pinole Regional Shoreline , part of the East Bay Regional Parks District . With the postwar baby boom and the desire for suburban living, large tract housing developers would purchase large central county farmsteads and develop them with roads, utilities and housing. Once mostly rural walnut orchards and cattle ranches,

The missions maintained authority over indigenous peoples and land holdings until the 1830s. At the peak of their influence in 1832, the coastal mission system controlled approximately one-sixth of Alta California. The First Mexican Republic secularized

2912-575: The Indian residents of the missions urged the priests to raid new villages to supply them with more women. As of December 31, 1832 (the peak of the mission system's development) the mission padres had performed a combined total of 87,787 baptisms and 24,529 marriages, and recorded 63,789 deaths. The death rate at the missions, particularly of children, was very high and the majority of children baptized did not survive childhood. At Mission San Gabriel , for instance, three of four children died before reaching
3003-566: The Mission Period); under Mexican rule the number rose to 21,066 (in 1824, the record year during the entire era of the Franciscan missions). During the entire period of Mission rule, from 1769 to 1834, the Franciscans baptized 53,600 adult Indians and buried 37,000. Dr. Cook estimates that 15,250 or 45% of the population decrease was caused by disease. Two epidemics of measles , one in 1806 and
3094-438: The Saklans who wanted nothing to do with the Spanish way of life. A punitive expedition was sent to the area in 1797 to repress the Saklans, and a battle was fought in modern-day Lafayette. In the early 1800s, many Saklan fled to the mission as a result of societal collapse from disease. By the 1810s the Saklan's tribal range was essentially devoid of inhabitants. Early interaction of these Native Americans with Europeans came with
3185-602: The Spanish colonization via the establishment of missions in this area, with the missions in San Jose, Sonoma, and San Francisco and particularly the establishment of a Presidio (a military establishment) in 1776. Although there were no missions established within this county, Spanish influence here was direct and extensive, through the establishment of land grants from the King of Spain to favored settlers. In 1821 Mexico gained independence from Spain. While little changed in ranchero life,
3276-649: The Spanish colonizers of the New World with the purpose of totally assimilating indigenous populations into European culture and the Catholic religion. It was a doctrine established in 1531, which based the Spanish state's right over the land and persons of the Indies on the Papal charge to evangelize them. It was employed wherever the indigenous populations were not already concentrated in native pueblos . Indians were congregated around
3367-657: The age of two. The high rate of death at the missions have been attributed to several factors, including disease, torture, overworking, malnourishment, and cultural genocide . Forcing native people into close quarters at the missions spread disease quickly. While being kept at the missions, native people were transitioned to a Spanish diet that left them more unable to ward off diseases, the most common being dysentery , fevers with unknown causes, and venereal disease . The death rate has been compared to that of other atrocities. American author and lawyer Carey McWilliams argued that "the Franciscan padres eliminated Indians with
3458-409: The area was first developed as low-cost, large-lot suburbs, with a typical low-cost home being placed on a "quarter-acre" (1,000 m ) lot — actually a little less at 10,000 square feet (930 square metres). Some of the expansion of these suburban areas was clearly attributable to white flight from decaying areas of Alameda County and the consolidated city-county of San Francisco , but much
3549-480: The attention of virtually every level of the bureaucracy. Once empowered to erect a mission in a given area, the men assigned to it chose a specific site that featured a good water supply, plenty of wood for fires and building materials, and ample fields for grazing herds and raising crops . The padres blessed the site, and with the aid of their military escort fashioned temporary shelters out of tree limbs or driven stakes, roofed with thatch or reeds ( cañas ). It
3640-474: The bayside portions opposite San Francisco and northern portions of Santa Clara County , were given up to form Alameda County effective March 25, 1853. The land titles in Contra Costa County may be traced to multiple subdivisions of a few original land grants. The grantee's family names live on in a few city and town names such as Martinez , Pacheco and Moraga and in the names of streets, residential subdivisions, and business parks. A few mansions from
3731-577: The construction of a house within a year. Fences were not required and were forbidden where they might interfere with roads or trails. Locally a large family required roughly 2000 head of cattle and two square leagues of land (fourteen square miles) to live comfortably. Foreign entrepreneurs came to the area to provide goods that Mexico could not, and trading ships were taxed. The exclusive land ownership in California by Hispanics in California would soon end.

The effects of the housing value crash (2008–2011) varied widely throughout the county. Values of houses in prosperous areas with good schools declined only modestly in value, while houses recently built in outlying suburbs in

Other areas could use the more limited water available from local creeks and from wells. Orchards dominated where such water was available, while other, seasonally dry areas were used for cattle ranching. In central parts of the county walnuts were an especially attractive orchard crop, using

Concerns have been raised by historians and Indigenous peoples of California about the way the mission period in California is taught in educational institutions and memorialized . The oldest European settlements of California were formed around or near Spanish missions, including

His letters were published in newspapers throughout the East which started the first wagon trains to California. He invited the settlers to stay on his ranch , and Rancho Los Meganos became
4277-467: The eastern part of the county experienced severe reductions in value, accelerated by high unemployment and consequent mortgage foreclosures, owner strategic walk-aways , and the too-rapid conversion of neighborhoods from owner-occupancy to rentals. Home values rebounded as the economy recovered from the recession. According to the U.S. Census Bureau , the county has a total area of 804 square miles (2,080 km ), of which 716 square miles (1,850 km )

Santa Barbara , and Santa Cruz were also formed near missions, and the historical imprint reached as far north as Sonoma in what became the wine country. Prior to 1754, grants of mission lands were made directly by the Spanish Crown. But, given the remote locations and the inherent difficulties in communicating with
4641-409: The geographic features of the particular site. Once the spot for the church had been selected, its position was marked and the remainder of the mission complex was laid out. The workshops , kitchens , living quarters, storerooms, and other ancillary chambers were usually grouped in the form of a quadrangle , inside which religious celebrations and other festive events often took place.

Plans to build a twenty-second mission in Santa Rosa in 1827 were canceled. The Rev. Pedro Estévan Tápis proposed establishing a mission on one of the Channel Islands in the Pacific Ocean off San Pedro Harbor in 1784, with either Santa Catalina or Santa Cruz (known as Limú to

On arriving home the men were instructed to throw their bows and arrows at the feet of the priest, and make due submission. The infants were then baptized, as were also all children under eight years of age; the former were left with their mothers, but the latter kept apart from all communication with their parents. The consequence was, first,
5005-408: The men engaged in building. The men worked a variety of jobs, having learned from the missionaries how to plow, sow, irrigate, cultivate, reap, thresh, and glean. They were taught to build adobe houses, tan leather hides, shear sheep, weave rugs and clothing from wool, make ropes, soap, paint, and other useful duties. The work day was six hours, interrupted by dinner (lunch) around 11:00 a.m. and
5096-580: The mission proper through forced resettlement, in which the Spanish "reduced" them from what they perceived to be a free "undisciplined'" state with the ambition of converting them into "civilized" members of colonial society. The civilized and disciplined culture of the natives, developed over 8,000 years, was not considered. A total of 146 Friars Minor , mostly Spaniards by birth, were ordained as priests and served in California between 1769 and 1845. Sixty-seven missionaries died at their posts (two as martyrs : Padres Luis Jayme and Andrés Quintana ), while
5187-410: The missions out of curiosity and sincere desire to participate and engage in trade, many found themselves trapped once they were baptized . On the other hand, Indians staffed the militias at each mission and had a role in mission governance. To the padres , a baptized Indian person was no longer free to move about the country, but had to labor and worship at the mission under the strict observance of

Mission lands were largely given to settlers and soldiers, along with a minority of indigenous people. The surviving mission buildings are the state of California's oldest structures and most-visited historic monuments, many of which were restored after falling into near disrepair in

Indigenous peoples often resisted and rejected conversion to Christianity . Some fled the missions while others formed rebellions. Missionaries recorded frustrations with getting indigenous people to internalize Catholic scripture and practice. Indigenous girls were taken away from their parents and housed at monjeríos . The missions' role in destroying Indigenous culture has been described as cultural genocide . By 1810, Spain's king had been imprisoned by

Young native women were required to reside in the monjerío (or "nunnery") under the supervision of a trusted Indian matron who bore the responsibility for their welfare and education. Women only left the convent after they had been "won" by an Indian suitor and were deemed ready for marriage. Following Spanish custom, courtship took place on either side of

If an Indian did not report for their duties for a period of a few days, they were searched for, and if it was discovered that they had left without permission, they were considered runaways. Large-scale military expeditions were organized to round up the escaped neophytes. Sometimes, the Franciscans allowed neophytes to escape

Once a Native American " gentile " was baptized, they were labeled a neophyte , or new believer. This happened only after a brief period during which the initiates were instructed in the most basic aspects of the Catholic faith. But, while many natives were lured to join
