History of Puerto Rico

As a consequence of the Jones Act and the establishment of elections, a new political party, the Partido Nacionalista de Puerto Rico (Puerto Rican Nationalist Party), was founded on September 17, 1922. In the 1930s, the Nationalist Party, led by Pedro Albizu Campos withdrew from political participation and increased conflict arose between their adherents and the authorities. They attacked Blanton Winship, the appointed Governor of Puerto Rico, Elisha Francis Riggs Chief of Police, and Robert A. Cooper Judge of the Federal Tribunal in Puerto Rico. On February 23, 1936, two Nationalists Hiram Rosado and Elias Beauchamp, in retaliation for the "Rio Piedras Massacre," killed Police Chief Riggs in San Juan. They were apprehended and summarily executed at police headquarters. On July 31, 1936, Pedro Albizu Campos, Juan Antonio Corretjer, Clemente Soto Vélez and other Nationalists were sentenced to six to 10 years in federal prison. Later, on March 21, 1937, police opened fire at a Nacionalista de Puerto Rico (Puerto Rican Nationalist) Party parade, known
as the "Ponce Massacre"; 20 people (including two policemen) were killed and 100 were wounded. In the 1920s, the economy of Puerto Rico boomed. A drastic increase in the price of sugar, Puerto Rico's principal export, brought increasing revenues to the island. As a result the island's infrastructure was steadily upgraded. New schools, roads and bridges were constructed. The increase in private wealth was reflected in the erection of many residences, while the development of commerce and agriculture stimulated the extension of banking and transport facilities. The high infant mortality death rate of the late 19th century declined steadily, thanks in large measure to basic public health programs. However, the economic growth would come to a screeching halt in 1929 when the United States stock market crashed. This period of prosperity came to an end with the onset of the Great Depression. At the time, agriculture was the main contributor to the economy. Industry and commerce slowed during the 1930s as well. The depression was further aggravated when on September 27, 1932, Hurricane San Ciprián struck the island. Exact figures of the destruction are not known but estimates say that 200–300 people were killed, more than a thousand were injured, and property damage escalated to $30–50 million. The agricultural production, the principal economic driver for the island, came to a standstill. However, the decline of the economy would not end there. A new federal minimum wage law of 25 cents an hour took effect in 1938. As a consequence, two-thirds of the island's textile factories closed because worker productivity was below
