A key supporter of Díaz was former Lerdista Manuel Romero Rubio. According to historian Friedrich Katz, "Romero Rubio was in many respects the architect of the Porfirian state." The relationship between the two was cemented when Díaz married Romero Rubio's young daughter, Carmen. Romero Rubio and his supporters did not oppose the amendment to the Constitution to allow Díaz's initial re-election and then indefinite re-election. One of Romero Rubio's protégés was José Yves Limantour, who became the main financial adviser to the regime, stabilizing the country's public finances. Limantour's political network was dubbed the Científicos, "the scientists", for their approach to governance. They sought reforms, such as decreasing corruption and increasing uniform application of laws. Díaz opposed any significant reform and continued to appoint governors and legislators and control the judiciary.
