INTRODUCTION

Mercedes, Texas, the “Queen City,” is located in the southeastern corner of Hidalgo County only five miles from the Mexican border in South Texas in a geographic area known as the Lower Rio Grande Valley. The “Valley” is not a true valley, but a river delta formed as the Rio Grande empties into the Gulf of Mexico. Before the advent of river dams and levees, the Rio Grande flooded annually, much as the Nile did in Egypt, creating rich, fertile soil in a narrow band suitable for limited agriculture.

The earliest known inhabitants of this area were called Coahuiltecans by anthropologists who grouped all of the separate native indigenous groups together. Later studies of the copious annotations of Spanish entradas, or exploratory expeditions, to this area in the 1600s revealed that many different groupings existed, each with their own language and customs. These early explorations noted that there were numerous native settlements the Spanish called rancherías.

Under the leadership of José de Escandón, the Count of Sierra Gorda, Spanish colonists migrated in the mid-1700s to the northern reaches of Nueva España, or New Spain, to the region called Nuevo Santander, which reached from Tampico to the Nueces River. On both the southern and northern banks of the lower Rio Grande, Escandón established six villas or townships between 1749 and 1755, and numerous land grants called porciones were apportioned out. These porciones were narrow strips of land that each had access to the river to ensure that water was available to each landowner. Because of the climate, topography and soil composition, these Spanish colonists decided that ranching was best suited to the area, with some subsistence farming in selected areas near the river waters or the resacas through the use of acequias, or irrigation channels, that used gravity to move the water streams.

In 1778, Juan José Hinojosa, a captain and chief justice at the villa of Reynosa, petitioned the king of Spain for the Llano Grande land grant on the north side of the Rio Grande where the city of Mercedes is now located. This royal land grant contained 25 leagues of land with 15 miles of river frontage, or more than 100,000 acres. By the time the grant was approved in 1790, Hinojosa had died, and his grant was divided up amongst his eight heirs. Mercedes was later established on what were parts of shares five, six, and seven.

Mexico’s separation from Spain in 1821 and the Texas Independence of 1836 disrupted the everyday business of the ranching communities, and many Mexican-heritage inhabitants of Texas began calling themselves Tejanos. The Mexican–American War in 1848 profoundly impacted the area when the original landowners, suddenly now US citizens, were forced to protect their land claims in land adjudication courts. Being land-rich but cash-poor, many were able to do so successfully but still lost land when they were forced to pay the American lawyers’ fees and their property taxes with acreage.

During the Civil War, when the Rio Grande was the only waterway available to the Confederate cotton growers for shipping to market, the value of the river and the region was noted by northern venture capitalists. Many Anglos had come to the Valley during the Mexican–American War and the Civil War to make their fortunes, and many married Mexican heiresses. By 1865, northern eyes were set on the Rio Grande Valley and interest grew in developing international trade and commercialized agriculture in this region.

In July 1904, the Sam Fordyce Branch of the St. Louis, Brownsville and Mexico Railway reached Section 14 and established the stop that would later become Mercedes, declared the “Sweetheart of the Branch.” Upon visiting the Valley, railroad magnate Benjamin F. Yoakum became convinced that commercialized agriculture was a viable venture in the Rio Grande Valley. Yoakum convinced a group of investors to form the American Rio Grande Land and Irrigation Company to purchase land and develop an irrigation system that would transform the Lower Rio Grande Valley into an area of profitable commercialized agriculture.

The American Rio Grande Land and Irrigation Company purchased land from the Capisallo Town and Improvement Company belonging to Lon C. Hill in 1907 with the intention of making the town its company headquarters. Hill had already platted a town and named it Capisallo, then later renamed it Lonsboro. The American Rio Grande Land and Irrigation Company then decided to move the site west about a mile to an area called the Pear Orchard. It was so named because of the abundance of cacti bearing prickly pear fruit in that location. Mercedes was officially founded on September 15, 1907.

By sheer force of manual labor, thousands of Mexican and Tejano laborers with pick, shovel, and hoe cleared the land, and the town was finally mapped out in its present location. The American Company directors decided to rename the town Díaz because they greatly admired Mexican president Porfirio Díaz but then changed it to Mercedes, somehow erroneously believing that President Díaz’s wife’s name was Mercedes. But Díaz’s first wife was named Delfina, and his second wife was named Carmen, so the choice of name remains a mystery to this day. No known primary sources exist explaining the choice of name. Unfortunately, numerous published works since the early days have reported that the name Mercedes referred to President Díaz’s wife, and the inaccuracy has been repeated many times.

It should be noted that the phrase mercedes reales means “royal grants” and mercedes de tierra means “land grants.” It is possible that somehow, someone who heard these phrases mistakenly believed Mercedes to be a person; namely, President Díaz’s wife. The phrase mercedes reales also gives a connection to the choice of the nickname “Queen City” for the town of Mercedes because “real” which means “royal” could have made someone think Mercedes referred to a royal person; namely, a queen. In reality, mercedes reales referred to the fact that the porciones and the larger land grant tracts such as the Llano Grande were royal gifts.

On March 8, 1909, Mercedes became incorporated and elected a mayor and city council. The town grew rapidly as the Mercedes Commercial Club, forerunner of the Mercedes Chamber of Commerce, aggressively promoted land development. The winter vegetable and citrus farms began producing immediately, and Mercedes became a major exporter of produce, citrus fruits, and cotton. In 1939, Mercedes promoted an annual agricultural and livestock show that became the Rio Grande Valley Livestock Show. In 2014, the Rio Grande Valley Livestock Show celebrated its 75th anniversary.

As did most Valley cities, Mercedes experienced growing pains with bandit troubles, the effects of World War I and II, influenza and smallpox epidemics, hurricanes, floods, droughts, freezes, and the Great Depression. Mercedes overcame these obstacles and continued to thrive. The town established many churches and businesses and an excellent school system. Mercedes has produced notable citizens in the fields of art, literature, music, business, education, government, athletics, and science among others; and although it has produced excellence, its noble work is not yet done.
