Educated in Guadalajara, he entered politics in his home state and supported educational and secularizing reforms. In Mexico City he wrote for periodicals including El Siglo XIX and served in Congress and several ministries. His financial writings emphasized the difficulty of governing without consistent accounts or a coherent revenue system.","As foreign secretary during the final phase of the war with the United States, he helped secure the peace settlement. He sought written clarification of American changes to the Treaty of Guadalupe Hidalgo, leading to the Protocol of Querétaro. Appointed minister in Washington after the war, he then defended that protocol's validity when American administrations disputed its binding force. Mexico eventually instructed him to stop pursuing the matter.","His Washington correspondence also addressed the proposed interoceanic route across Tehuantepec. In a detailed communication to Daniel Webster in 1851, he distinguished a treaty facilitating transit from the private concession originally granted to José Garay. He argued that the concession's validity belonged before Mexico's courts and warned that opposition in Congress made ratification difficult. Webster rejected that interpretation and maintained that protection of the concession holders was central to the agreement.","De la Rosa returned to public office after the fall of Santa Anna, again serving as foreign secretary under Ignacio Comonfort and participating in the constituent congress. He also directed the Colegio de Minería. His publications ranged from travel impressions of the journey to Washington to agriculture and the organization of public administration. He died in Mexico City in September 1856."],"id":"mexico:mx-luis-de-la-rosa-oteiza","identifiers":{},"legacyPersonIds":[],"legacyUrl":"https://chanceries.org/diplomat-c4104a484aedaf7af295.html","name":"Luis de la Rosa Oteiza","notes":[],"paragraphSources":[["rosa-udg","rosa-hacienda"],["rosa-udg","rosa-washington"],["rosa-note","rosa-webster"],["rosa-udg"]],"profileUrl":"diplomat-c4104a484aedaf7af295.html","relatedEvents":[{"basis":"reviewed-context","country":"Mexico","date":"1848-02-02","description":"The Treaty of Guadalupe Hidalgo ends the Mexican–American War.
