Tourists flock to Baja California—separated from the rest of Mexico by the Sea of Cortez—to visit its stunning shoreline and test their mettle at sport fishing. The state’s border crossing at Tijuana is the busiest in all of Mexico. The international port of Ensenada, located on the Pacific coast, is a regular stop for cruise ships. Since it is the only deepwater port in Baja California, it acts as the primary hub for importing and exporting goods throughout the region.


Early History
Before the Spaniards arrived, the peninsula of Baja California was inhabited by three major ethnic groups: the Cochimí in the north, the Guaycura in the central section and the Pericú on the southern cape. Archaeological artifacts suggest that these tribes inhabited the peninsula and Cedros Island as early as 9,000-10,000 years ago. The Cochimí, who lived on the mainland, were hunters and gatherers, but an isolated group of Cochimí living on Cedros Island developed a fairly complex agricultural system. The Guaycura and the Pericú lived by hunting, gathering and fishing. Their descendants still live in Baja California, primarily on the northernmost part of the peninsula.

Did you know? When the Spaniards arrived in the Baja California area in 1539, they believed they had reached a mythical island of female warriors governed by Queen Calafia. The earliest record of this myth appears in The Exploits of the Very Powerful Cavalier Esplandian, Son of the Excellent King Amadis of Gau, written by Garcia Ordonez de Montalvo 18 years earlier.

Middle History
After the Spanish conquered the Mexican mainland early in the 16th century, they began searching westward for a fabled island of gold. In 1532, the conquistador Hernán Cortés dispatched two fleets of ships to look for the island. When they failed to find it, Cortés decided to lead the search himself. In 1535, he landed north of La Paz (near the southern end of the Baja California peninsula) where he discovered black pearls but no gold. Cortés and his men returned to the mainland, only to launch another expedition in 1539 under the leadership of Captain Francisco de Ulloa. This time the Spaniards sailed the full length of the Sea of Cortés, discovering that Baja was actually a peninsula. Conflicting reports state that Ulloa was stabbed to death or lost at sea the following year; in either case, Cortés returned to Spain in 1541 without fully exploring or colonizing Baja California. In 1542, Juan Rodríguez Cabrillo ventured into the region, but it proved to be the last exploration for 50 years.

Later, as trade grew between Mexico and the Philippines, it became clear that a supply station on the western coast of Baja California would provide a welcome refuge for ships arriving from the long Pacific voyage. Beginning in 1592, Sebastián Vizcaíno undertook two expeditions to establish such a station, but he was unsuccessful because of repeated native resistance. In fact, a supply station would not be established in the area until 1730.

In January 1683, the Spanish government provisioned three ships with 200 men and gave them a mandate to colonize the peninsula. The expedition, led by Sinaloa’s governor Isidro de Atondo y Antillón, sailed into the Sea of Cortés and attempted its first settlement at La Paz; however, hostility from local tribes forced the expedition to move on. When a second settlement failed for the same reason, the expedition returned to the mainland.

Twelve years later, in 1695, a Jesuit priest named Juan María Salvatierra established the region’s first permanent Spanish settlement, the Misión Nuestra Señora de Loreto, which quickly became the peninsula’s religious and administrative capital. Its success enabled other Jesuits to introduce more missions throughout the area—a total of 23 over the next 70 years. However, King Carlos III of Spain became wary of the Jesuits’ growing power and, in 1767, ordered that they be expelled at gunpoint and returned to Spain immediately.

The Franciscans moved into the vacuum left by the Jesuits, and—under the authority of Father Junipero Serra—they closed or consolidated several of the existing missions and established one of their own, San Fernando Velicatá. At the direction of the Spanish government, Father Serra continued to move north, where he established 21 new missions in Alta California (present-day California).

In the late 1700s, the Dominicans became active in Baja California. By 1800, they had established nine new missions in the northern part of Baja and continued to oversee the existing Jesuit missions.

The independence movement in Mexico began in 1810, but Baja California’s involvement was minimal, given its small population. The Spanish presence on the peninsula consisted primarily of missions, and the missions were closely linked to the Spanish crown. The end of Spanish rule in Mexico spelled the end of the missions’ administrative authority as well. After gaining its independence in 1821, Mexico established Baja California as a federal territory; in 1832, the governor converted all the missions into parish churches.

Recent History
The Mexican-American War (1846-1848) had major repercussions in Baja California. The war began after Mexico refused the United States’ offer to buy California, Nevada, Utah and parts of Colorado, Arizona, New Mexico and Wyoming. In the treaty ending the war, Mexico gave in to U.S. demands and ceded the vast territory in exchange for $15 million. The original draft of the treaty included Baja California in the sale, but the United States eventually agreed to omit the peninsula because of its proximity to Sonora, which is located just across the narrow Sea of Cortés.

In 1853, an American named William Walker invaded the peninsula with 50 mercenaries, intent on annexing the land for the United States. Although he had no support from the U.S. government, Walker sailed from San Francisco to La Paz, arrested the governor, took possession of the public buildings and raised the flag of a new republic. He even declared himself president and installed cabinet members. Without reinforcements, however, Walker was forced to retreat, first to Cabo San Lucas and eventually back across the border.

Being so distant from Mexico City, Baja California was relatively insulated from much of the political and social turmoil that plagued Mexico during the latter part of the 19th century. However, the territory did play a pivotal role in the Mexican Revolution. In 1911, a group called the Partido Liberal Mexicano (Liberal Mexican Party) organized a rebellion against the extended presidency of dictator Porfirio Díaz. Under Francisco Palomares and Pedro Ramirez Caule—both supporters of Francisco Madero, who initiated the Mexican Revolution in 1910—the rebel army took control of Mexicali in January 1911, followed by Tijuana in May. The success of the Partido Liberal Mexicano undermined the credibility of Díaz and the federal forces, encouraging rebel troops in other regions to join the fight.

As the revolution drew to a close in 1921, Baja California aligned itself with the new president, Venustiano Carranza. Throughout the remainder of the 20th century, the state’s cititens chose their leaders from the dominant political party, the PRI (Institutional Revolutionary Party), with the exception of Ernesto Ruffo, who was elected in 1989 as a representative of the PAN party.

On December 31, 1952, Baja California officially became Mexico’s 29th state, and in 1953 the state’s constitution was adopted. Previously, the region’s official name was Territorio Norte de Baja California, or Northern Territory of Baja California. Under the new constitution, Braulio Maldonado Sández of the Institutional Revolutionary Party (PRI) became the state’s first governor, presiding over a government whose unicameral legislative branch comprised 25 members.

Baja California Today

The state’s economy is bolstered by agriculture, maquiladoras (manufacturing assembly plants), mining and tourism. The state is also well known as a tourist destination, thanks to its countless beaches and proximity to the United States. With six border crossing points into the U.S. state of California, Baja California sees many thousand crossings each day. In 2000, an estimated 180,000 cars crossed the international border daily.

Tijuana is the largest Baja California city. Its population continually fluctuates as people arrive from the United States and Latin America countries while others depart for the United States.

Baja California`s sports fans enjoy proximity to several professional teams: the Mexicali Suns (basketball), the Mexicali Eagles (baseball), the Tijuana Colts (baseball) and the Tijuana Xoloitzcuintles (soccer).

Fun Facts

  • Baja California’s coat of arms features the state’s motto, “Work and social justice,“ emblazoned across an image of the sun that represents the state’s energy. Beneath the sun, a male figure holds a book, while a female figure carries a test tube; together, they grasp several lightning bolts, suggesting that the creative combination of culture and science can generate powerful energy. On the lower part of the design, a human figure with outstretched arms embraces the state’s three primary resources: agriculture, industry and the ocean. Two leaping fish on the sides denote the two bodies of water that surround Baja California—the Sea of Cortés and the Pacific Ocean.
  • The peninsula of Baja California is 1,300 kilometers (800 miles) long, making it the world’s third-longest.
  • The U.S. border crossing at Tijuana is one of the busiest in the world, with about 50,000 cars and 25,000 pedestrians coming and going each day.
  • When the Spaniards arrived in the Baja California area in 1539, they believed they had reached a mythical island of female warriors governed by Queen Calafia. The earliest record of this myth appears in The Exploits of the Very Powerful Cavalier Esplandian, Son of the Excellent King Amadis of Gau, written by Garcia Ordonez de Montalvo 18 years earlier.
  • The Guadalupe Valley, near Ensenada, supports several world-class wineries located in the old Nuestra Señora de Guadalupe del Norte mission. Visitors to the mission can enjoy wine tasting and vineyard tours.
  • Olive Ridley (golfinas) and Leatherback (laud) turtles nest on the state’s beaches, returning each year to lay their eggs on the same beach where they were born.
  • La Bufadora (the blowhole) is a natural marine geyser located a short distance from Ensenada. Ocean waves are forced into a partly submerged cave. The water and air in the cave mix and cause a pressure build-up. The pressure causes the water to explode upwards out of the cave, reaching heights of up to 24 meters (80 feet).
  • El Altar, a site in San Pedro Mártir National Park, provides visitors with the unique opportunity to see both the Pacific Ocean and the Sea of Cortés at the same time.



The beaches along Baja California’s two coasts vary tremendously. The western coast, which faces the Pacific Ocean, is characterized by cool water, ocean swells and occasional heavy surf. The eastern coast faces the narrow Sea of Cortés and generally has calmer waters.

Each year, thousands of tourists travel to Baja to take advantage of sport fishing at Ensenada, San Felipe, Mexicali, Bahía de Los Ángeles and San Quintín.

Wine Country

The northern part of Baja California has an ideal climate for grape growing; the valleys of Calafia, Guadalupe and San Antonio de las Minas constitute the heart of the Baja California wine country, producing a wide variety of wines such as chardonnay, chenin blanc, sauvignon blanc, barbera, cabernet, syrah, tempranillo, merlot and cabernet franc. The Bodegas de Santo Tomas wineries continue to use the grape varieties planted by Jesuit missionaries in the 18th century.

Spanish Missions

Although the area resisted European colonization for more than a century after its discovery, the Spanish eventually colonized it by establishing missions. Many of the missions are in poor condition or have disappeared completely, but tourists still visit sites such as Misión San Vicente Ferrer, Misión El Descanso and Misión San Miguel Arcángel de la Frontera.

Cave Paintings

Ancient paintings, some of which were created by early humans around 8000 B.C, adorn caves and rock dwellings throughout the peninsula. Baja California’s cave painting route begins in the north at El Vallecito, near the town of La Rumorosa, and stretches south of the Guadalupe Valley to an area called Las Pintas.
