As more English-speaking Americans arrived in New Orleans, tensions between them and the settled Creoles began to grow. When two American developers approached Marigny about future commercial development of the city in the area of the Faubourg Marigny, the Creole first agreed, and then reneged by instructing Madame Marigny to stay away from the notary office, thus effectively killing the deal; this was reportedly due to his notorious dislike of the American settlers who were considered uncouth "parvenus". This act was seen as extremely bad faith on the part of Marigny, and not only ensured that housing development grew uptown instead of east of the city, but also affected both his finances and his political career: "Marigny was severely blamed by the rest of the Creole population for thus yielding to his anti-American prejudices. This feeling ultimately worked his political destruction. Thereafter he was not looked on as a safe leader, and when he became a candidate for the governorship, they refused to support him."
