Chief Balthazar: Copano-Karankawa Leader and Peace Negotiator in 18th Century Texas (unknown–unknown)

Balthazar (also spelled Baltazar, Balthasar, and Baltasar) was a Copano-Karankawa chief who negotiated for peace during the Karankawa-Spanish War (1778–89) then advocated the reestablishment of Nuestra Señora del Rosario Mission. Considering Balthazar spoke Castilian Spanish fluently, he very possibly spent his childhood living in Mission Rosario. The Copano (or Copane) Indians were willing to work with the Spanish, and likely Balthazar spent considerable time periodically visiting and living at some of the missions. In historical documents, he served as a mediator and negotiator for the Copano tribe and the Spaniards during European colonization in the late eighteenth century.

 The Copano people resided between Copano Bay and San Antonio Bay on the Texas coast. Balthazar was documented (and therefore baptized) as a Christian at Mission Rosario. His history may have gone back to the mission’s founding, but that information is not confirmed. He adopted Christianity and urged the Copano people to do the same, in part as a practical measure to survive the rapid changes of the colonial landscape. The yearslong Karankawa-Spanish war between various groups of Karankawas and the Spanish included the abandonment of Mission Rosario in 1778, as forced by apostate Karankawas led by Guapite-Karankawa leader Joseph María.

Chief Balthazar was documented as a Copano leader who effectively engaged in the Spanish mission system and lived in Mission Rosario. He was adamant about ending the Karankawa-Spanish War and carried out his plan by negotiating with the Spaniards. On November 10, 1789, Chief Balthasar, accompanied by seven leaders who represented the other various Karankawa-cultured tribes, met at Presidio La Bahía to renegotiate a peace treaty. Interim governor Rafael Martínez Pacheco believed that the price of supplies was far less costly than engaging in war with the Karankawas, and so he ordered the captain of La Bahía, Manuel de Espadas, to welcome the Karankawas—long labeled as enemies—and  provide supplies to the ones who showed their loyalty.

Balthazar also aided in the reestablishment of Mission Rosario as part of the end of the Karankawa-Spanish War, and Nuestra Señora del Refugio Mission was later established on the Texas coast in the effort to provide a mission and Christian conversion closer to the home of the Karankawa groups. By the end of the war, Balthazar was one of two Copano leaders, along with another from the Cujane tribe, who entered San Antonio and offered to resettle Mission Rosario. Their motive behind their desire to return was strategic. The Copano people believed that converting to Christianity and supporting a good standing relationship with the Spaniards would provide them with protection and supplies. Moreover, Karankawa leaders such as Balthazar likely regarded their return to the mission as a means of advancing their own wealth and authority. Balthazar was also a strong supporter of Mission Rosario's Padre José Mariano Reyes and in November 1789 implored that he remain at the mission. In a letter to Martínez Pacheco on March 24, 1790, Manuel de Espadas acknowledged his instructions to reconnoiter the Texas coast with Balthazar and other warriors to “familiarize” himself with that country.

In a letter to Martínez Pacheco and dated April 9, 1790, Espadas reported an incident at Mission Rosario in which Copano leader Manuel Alegre attempted to assert his dominance over the Karankawas by violently grabbing Chief Balthazar by the hair and snatching his baston (ceremonial staff). Infuriated and embarrassed, Balthazar and the Copano people demanded Alegre’s removal. In response, the Spaniards removed Alegre and sent him to San Antonio. Balthazar secured limited protection for the Copanes from aggressive colonial forces and rival tribes. The Spaniards viewed Balthazar as a better ally, and he selectively adapted under colonial pressure, demonstrating his resilience and love for the Copano tribe.

Chief Balthazar was listed in a census report from Mission Rosario on May 1, 1790. The census also listed his wife, Castilda, another member of the Copano tribe. He disappeared from the archival records after this census.
