  When oil was discovered in the Venezuelan Maracaibo Basin town of Mene Grande in 1914, Curaçao's economy was dramatically altered. In the early years, both Shell and Exxon held drilling concessions in Venezuela, which ensured a constant supply of crude oil to refineries in Aruba and Curaçao. Crude oil production in Venezuela was inexpensive. Both Shell and Exxon were vertically integrated and controlled the entire industry, from pumping, transporting, and refining to sales. The refineries on Aruba and Curaçao operated in global markets and were profitable partly because of the margin between the production costs of crude oil and the revenues the sale of oil products. This provided a safety net for losses incurred through inefficiency or excessive operating costs at the refineries.
  
  In 1929, Curaçao was attacked by Venezuelan rebel commander Rafael Simón Urbina, who, with 250 soldiers, captured the fort. The Venezuelans plundered weapons, ammunition, and the island's treasury. They also managed to capture the Governor of the island, Leonardus Albertus Fruytier (1882–1972), and hauled him off to Venezuela on a stolen American ship, Maracaibo. Fruytier was criticized and had to resign as governor. After returning to the Netherlands, he settled for a position as chief inspector in Maastricht. The Dutch increased their military presence on the island.
  
  In 1936 a burning bale of cotton thrown overboard by the crew of the M. S. Colombia, which lay anchored in the Schottegat, caused the oil floating on the water to catch fire. It took days to get the fire under control; houses had to be evacuated, but there were no casualties.
  
  During the Second World War, the island played an important role in the supply of fuel for the Allied forces. In 1940, before the invasion of the Netherlands by Nazi Germany, the British occupied Curaçao and the French Aruba. The presence of powers other than the Netherlands alarmed the Venezuelan government given the proximity of these islands at the entrance to the Gulf of Venezuela and the fact they'd historically been used as bases to launch incursions against Venezuelan territory. In 1941, US troops occupied the island and built military airport "Hato". The main purpose was this deployment was to fight against expected future attacks by Axis submarines and potentially long-distance Nazi bombers. America was also concerned over the potential threat of a German invasion of the continental US launched with the aid of German settlers in South America.
  
  In 1942 the port of Willemstad, one of the main sources of fuel for the Allied operations, was besieged by German submarines on several occasions under Neuland Operation. In August 1942, the Germans returned to Curaçao and attacked a tanker and received fire from a Dutch shore battery before slipping away. The US Navy established the Fourth Fleet, which was responsible for countering enemy naval operations in the Caribbean and in the South Atlantic. The US Army also sent aircraft and personnel to help protect the oil refineries and bolster the Venezuelan Air Force.
  
  In 1954, Curaçao and other Dutch Caribbean colonies were joined to form the Netherlands Antilles. Discontent with Curaçao's seemingly subordinate relationship to the Netherlands, ongoing racial discrimination, and a rise in unemployment owing to layoffs in the Shell refinery led to a series of riots in 1969. A state of emergency was declared after rioters set fire to the Willemstad downtown and the bankers mansions. Protestors had to face the Dutch Navy marines dispatching from the local military base on the island, in order to quell the rebellion led by charismatic politicians as Papa Godett and Stanley Browne. The riots resulted in two deaths, numerous injuries and severe damage in Willemstad. In response, the Dutch government introduced far-reaching reforms, allowing Afro-Curaçaoans greater influence over the island's political and economic life, and increased the prominence of the local Papiamentu language.
  
  Curaçao experienced an economic downturn in the early 1980s. Shell's refinery on the island operated with significant losses from 1975 to 1979, and again from 1982 to 1985. Persistent losses, global overproduction, stronger competition, and low market expectations threatened the refinery's future. In 1985, after 70 years, Royal Dutch Shell decided to end its activities on Curaçao. This came at a crucial moment. Curaçao's fragile economy had been stagnant for some time. Several revenue-generating sectors suffered even more during this period: tourism from Venezuela collapsed after the devaluation of the bolivar, and a slowdown in the transportation sector had deleterious effects on the Antillean Airline Company and the Curaçao Dry Dock Company. The offshore financial services industry also experienced a downturn due to new U.S. tax laws.
  
  In the mid-1980s, Shell sold its refinery for the symbolic amount of one Antillean guilder to a local government consortium. In recent years, the aging refinery has been the subject of lawsuits alleging that its emissions, including sulfur dioxide and particulate matter, far exceed safety standards. The government consortium leases the refinery to the Venezuelan PDVSA state oil company.
  
  Continuing economic hardship in the late 1990s and early 2000s resulted in much emigration to the Netherlands.
  
  On 1 July 2007, Curaçao was due to become a country within the Kingdom of the Netherlands, like Aruba and the Netherlands Antilles. On 28 November 2006, the change was delayed when the island council rejected a clarification memorandum on the process. A new island council ratified this agreement on 9 July 2007. On 15 December 2008, Curaçao was again scheduled to become a separate country within the Kingdom of the Netherlands. A non-binding referendum on the move was held in Curaçao on 15 May 2009; 52% of voters supported it.
