Mexican oil expropriation
The Mexican oil expropriation (Spanish: expropiación petrolera) (also petroleum expropriation, petroleum nationalization, etc.) was the expropriation of all oil reserves, facilities, and foreign oil companies in Mexico on March 18, 1938. It took place when President and General Lázaro Cárdenas declared that all mineral and oil reserves found within Mexico belong to the nation.
It is one of the Fiestas Patrias of Mexico, celebrating the date when the President, General Lázaro Cárdenas, declared that all oil reserves found in Mexican soil belonged to the nation, following the principle stated in the Article 27 of the Constitution of 1917. This measure caused an international boycott of Mexican products in the following years, especially by the United States, the United Kingdom and the Netherlands.
|History of Mexico|
The political support of labor unions and the founding of Petromex (now called Pemex) immediately after taking power by President Lazaro Cardenas, were the proximate events closest to the Petroleum Expropriation.
In 1924, after several failed strike efforts and break-ups by the Mexican Army, a strike began in Tampico against the refinery “El Aguila”, in which workers emerged triumphant and achieved recognition from the management for the labor union and reached a collective bargaining agreement.
On August 16, 1935, the Petroleum Workers Union of Mexico (Sindicato de Trabajadores Petroleros de la República Mexicana) was formed and one of the first actions was the writing of a lengthy draft contract transmitted to the petroleum companies demanding a 40 hour working week, a complete paid salary in the event of virtually unlimited time off for personal or family sickness, and claimed to replace the distinct collective contracts governing labor relations.
On November 3, 1937, the union demanded that the companies sign the collective agreement and on May 17, the union summoned a strike in case their demands were not met. In the early days of June, the union sued the companies before the General Arbitration and Conciliation Board (Junta General de Conciliacion y Arbitraje). The aforementioned strike started on a limited basis on May 31 and fully burst open on June 9.
The petroleum workers struggle was well regarded by the President and the population despite problems caused by the petroleum shortage. In July, as instructed by the arbitration board, a commission of financial experts was formed that investigated the petroleum companies finances, concluding that their profits easily permitted them to cover the demands of the workers. The companies, however, insisted the demands would cripple production and bankrupt them.
But, on December 8, the companies hired other unemployed workers and had not responded to the arbitration board. On December 18, 1937, the board gave a verdict in favor of the union by means of a “laudo” (binding judgment in arbitration) which demanded that the companies fulfill the requirements of the petitions and pay 26 million pesos in lost salaries. The petroleum companies initiated a lawsuit on January 2, 1938 before the Mexican Supreme Court to protect their property from the labor union and arbitration board, which denied the request.
Consequently, the foreign companies rebelled against the imposed contract, and the maximum Judicial Authority responded by rendering a decision on March 1, giving the companies until March 7 to pay the 26 million pesos penalty.
In 1935, all companies in the business of extraction, processing, and exporting of oil in Mexico were foreign companies with foreign capital. These companies attempted to block the creation of labor unions and used legal and illegal tactics to do so. However, the creation of individual unions within each company was made possible, but work conditions differed from one another.
On December 27, 1935, the Sindicato Único de Trabajadores Petroleros was created, despite the legal opposition in the states of Tamaulipas and Veracruz. On January 29, 1936, this union joined the Comité de Defensa Proletaria ("Committee of Proletarian Defense") which would become in February the Confederation of Mexican Workers (CTM). On July 20, the union celebrated its first convention, in which it was proposed a project of general contracts for each oil company and it was decided on a strike to push towards an agreement.
Lázaro Cárdenas intervened between the union and the oil companies in order to force an agreement on the contract. The strike was delayed for six months, but the companies never agreed to the contract and on May 28, the strike took place. The entire country was paralyzed for 12 days, with consumers unable to buy gasoline. Cárdenas convinced the union to end the strike until a decision by the companies could be made. However, the companies declared themselves unable to meet the demands because of financial problems. Cárdenas ordered an investigation and on August 3, the findings were that the Mexican oil industry produced higher returns than the U.S. oil industry.
Legal conflicts 
After the publication of the findings, the oil companies threatened to leave Mexico and take all of their capital with them. The government entity in charge of the conflict between these companies and the union, the Junta Federal de Conciliación y Arbitraje (Federal Conciliation and Arbitration Board), was not able to make a decision quickly and the union declared a 24-hour strike in protest on December 8.
On December 18, the Arbitration Board declared in favor of the union. The oil companies had to pay 26 million pesos of wages lost because of the strike, but they appealed to the Supreme Court. The Supreme Court then rejected the appeal and ordered them to raise salaries and improve working conditions for the union members. The oil companies protested this decision and President Cárdenas mediated a compromise; the union would accept 26 million. Cárdenas offered to end the strike if the oil companies paid the sum. According to witnesses of this meeting, representatives of the oil companies asked the President "Who can guarantee that the strike will be over", to which the President replied "I, the President of the Republic." After the businessmen asked with sarcasm "You?" President Cárdenas ended the meeting saying "Sirs, we are finished!".
As a result, Cárdenas decided to expropriate the oil industry and create a national oil company.
March 18, 1938 
On March 18, 1938 President Cárdenas embarked on the expropriation of all oil resources and facilities by the state, nationalizing the U.S. and Anglo-Dutch (Mexican Eagle Petroleum Company) operating companies. Two hours before informing his cabinet of his decision, he made the announcement on the radio to the rest of the country. Five days later, a crowd of 100,000 (according to the press) rallied in support of Cárdenas (see photo).
On April 12, 1938, a crowd of thousands of women gathered in front of the Palacio de Bellas Artes to make donations to pay the debt to foreign companies. Donations varied from chickens to jewelry, since the women encompassed all social classes.
On June 7, 1938, President Cárdenas issued a decree creating Petróleos Mexicanos (PEMEX), with exclusive rights over exploration, extraction, refining, and commercialization of oil in Mexico. On June 20, PEMEX started operations.
In retaliation, the oil companies initiated a public relations campaign against Mexico, urging people to stop buying Mexican goods, and lobbying to embargo US technology to Mexico. Many foreign governments closed their markets to Mexican oil, hoping that PEMEX would drown in its own oil. Between 1938 and 1939, PEMEX survived by trading oil for money and machinery to European countries with fascist governments. In spite of the boycott, PEMEX developed into one of the largest oil companies in the world and helped Mexico become the world's fifth largest oil exporter.
Saturnino Cedillo, a cacique from San Luis Potosí and former Secretary of Agriculture, showed the strongest opposition to Cárdenas's measures. Cedillo had in the past supported Cárdenas in a conflict with ex-President Plutarco Elías Calles, but disagreed with his plan of reforms. On May 15 of the same year, the state congress of San Luis Potosí issued a decree where it refused to recognize Cárdenas as President and declared that the expropiación petrolera did not benefit the economy of Mexico. Cárdenas did not consider this a serious threat and minimized efforts to suppress the rebellion, instead choosing persuasion. The US government did not support the rebellion because it was more concerned that fascist and communist movements from Europe would spread to Mexico.
The key to the success of the measures taken by Cárdenas was not just to control the opposition, but to keep afloat an industry in the absence of qualified personnel. The government had to depend on the Sindicato de Trabajadores Petroleros de la República Mexicana (STPRM, or the Union of Oil Workers of the Mexican Republic) to resolve disagreements over the management of oil resources, and deal with threats of strikes and sabotage. In spite of these and technical challenges, local workers who replaced the foreign technicians were successful in making the new nationalized oil industry work. Josephus Daniels, U.S. ambassador to Mexico, explained to President Franklin D. Roosevelt and Secretary of State Cordell Hull that Cárdenas' reforms could not be undone, since his position as president and the position of PEMEX were secure.
Critics of the expropriation point out that since Pemex took control of the nation's petroleum, the company has been rife with corruption through every administration since that of Cárdenas, including both the PRI (Partido Revolucionario Institucional) and the PAN (Partido Accion Nacional). A recent book, Camisas Azules, Manos Negras (Blue Shirts, Black Hands), details the massive corruption that continues to this day. In addition, the casus belli of the expropriation was a wage hike of 26 million pesos. In fact, in the aftermath, not only was the promised wage hike postponed indefinitely, wages were actually cut.
