Henri Castro (born Moïse Henriques de Castro, July 17, 1786 – November 3, 1865), a Jewish Texan, was one of the most important empresarios of the Republic of Texas. Early life Castro, who was born in Bayonne, France, was a French diplomat of Portuguese-Jewish descent. He later immigrated to the United States, and became an American citizen in 1827. In 1838, he worked as a banker in France, and sought to secure a loan for the young Republic of Texas. He was then appointed as consul general for Texas by President Sam Houston. He recruited hundreds of families for emigration to Texas. Most came primarily from the Haut-Rhin department of Alsace, in eastern France. They traveled to Texas from 1843 to 1847, and settled in the Medina River valley, just west of San Antonio. The city of Castroville on the Medina River is named for him, as is Castro County in the Texas Panhandle. Castro himself settled for a time in Castroville.

The grants were limited to a given time period in which colonization had to take place. On February 15, 1842, Castro, in temporary partnership with Jean Jassaud, was issued two land grants by the Republic of Texas. The grants were for the colonization of 600 families (with an option to increase that number to 1000) in three years. The first 200 families had to be settled by August 15, 1843. One grant was about 600,000 acres, near what is now Starr County, along the Rio Grande. Castro did not fulfill the colonization of this grant. The other grant totaled 1,250,000 acres, west of San Antonio, and included the counties of Atascosa, Frio, La Salle, Medina, and McMullen. This second grant came to be known as Castro's Colony. Castro began recruiting from an office in Paris in 1842, and the first of his recruits sailed into the port of Galveston, Texas, on January 1, 1843. In the fall of 1843, Castro found recruits in Alsace, Baden, and Switzerland. Waves of his colonists departed for Texas in the winter of 1843 and spring of 1844. Castro left Europe for Texas on May 19, 1844, by way of New Orleans. He made it to San Antonio in July 1844 to meet with the
