The Nine Days and What Followed

On February 9, 1898, Puerto Rico inaugurated its first autonomous government. For the first time in four hundred years, Puerto Ricans governed themselves — their own parliament, their own cabinet, their own trade negotiations. The Carta Autonómica that Muñoz Rivera had won through diplomacy was finally real. It lasted six days before the world changed again. By July, American warships were shelling San Juan. By December, Spain had signed the island away. Puerto Rico went from colony to autonomous nation to colony again in less than a year.

Six Days of Autonomy

The Autonomous Charter of 1897 was not a gift. It was the product of decades of organizing, exile, imprisonment, and diplomatic pressure. Ramón Emeterio Betances had spent his life demanding it. Segundo Ruiz Belvis died in exile working toward it. Román Baldorioty de Castro was imprisoned for it. And in the end, it was Luis Muñoz Rivera who won it — not through revolution, but by exploiting Spain's weakness during the Cuban insurgency, negotiating directly with the liberal Sagasta government.

The charter was extraordinary by any colonial standard. Puerto Rico received a bicameral parliament, an executive cabinet responsible to that parliament, the power to negotiate international trade agreements, and control over its own tariffs, budgets, and civil law. Spain retained authority over defense and foreign affairs, but the internal governance of the island belonged to Puerto Ricans. The new government was inaugurated on February 9, 1898. On February 15, the USS Maine exploded in Havana harbor,¹ and everything that followed was decided elsewhere.

It is worth noting, however, that the autonomous government had barely begun to function when it was overtaken by events. The Insular Parliament did not convene its first session until July 17, 1898² — just one week before the American invasion began. The charter's institutions were inaugurated in February, but the practical machinery of self-governance was still being assembled when the war swept it away. This does not diminish the significance of what the Carta Autonómica represented — it was the most advanced instrument of self-government any Spanish colony had achieved — but it means that the autonomous government was cut short before its viability under Spain could be tested.

The Bombardment

The Spanish-American War began on April 25, 1898. It was fought over Cuba, but Puerto Rico was in the way. On May 12, a U.S. naval squadron under Admiral William T. Sampson bombarded San Juan for three hours. Shells struck civilian buildings, the cathedral, and private homes. Seventeen were wounded, none of them soldiers. The bombardment accomplished nothing military — the Spanish garrison was barely damaged — but it accomplished something else: it told Puerto Ricans that their autonomy was irrelevant to what was coming.

Before the invasion even began, the U.S. Navy imposed a blockade on the island. Ships carrying food, medicine, and trade goods were turned away. An island that imported much of its grain and codfish — staples of the working-class diet — was suddenly cut off. Hunger spread through the coastal towns. The blockade was not an act of war against Spain's military. It was an act of war against Puerto Rico's people.

The Invasion

On July 25, 1898, Major General Nelson A. Miles landed 1,300 troops at Guánica, on the southwestern coast.³ He chose Guánica instead of San Juan deliberately — it was undefended, and the landing met no resistance. Miles issued a proclamation declaring that the Americans came "bearing the banner of freedom" and promising to bring "the advantages and blessings of enlightened civilization." The language was missionary. The intent was strategic. Puerto Rico controlled the Mona Passage, the gateway between the Atlantic and the Caribbean, and the United States wanted it.

What Miles's proclamation did not mention — and what complicates a simple narrative of conquest — is that many Puerto Ricans initially welcomed the American arrival. After four centuries of Spanish colonial rule, the prospect of incorporation into a democratic republic held genuine appeal. In several towns, particularly in the south and west, American troops were greeted with enthusiasm. Puerto Ricans offered food, shelter, and intelligence to the advancing forces. The welcome was not universal, but it was widespread enough to be historically significant. The disillusionment came later, when it became clear that the United States had no intention of incorporating Puerto Rico as an equal — that liberation from Spain did not mean self-determination, but rather a transfer from one empire to another.

The military campaign was brief. American forces advanced north and east from Guánica, meeting light resistance from combined Spanish and Puerto Rican troops. The most significant engagements were at Coamo, where Spanish and Puerto Rican defenders were flanked and routed, and at Asomante, where defenders actually repelled the American advance — the only successful defense of the entire campaign. But it didn't matter. The war was decided in Cuba and at sea. On August 12, an armistice was signed. The shooting stopped. The occupation began.

The Treaty

On December 10, 1898, the Treaty of Paris was signed.⁴ Spain ceded Puerto Rico, Guam, and the Philippines to the United States. The price was $20 million for the Philippines. Puerto Rico was free — meaning it cost nothing. Article IX of the treaty stated that "the civil rights and political status of the native inhabitants" would be "determined by the Congress." Not by the inhabitants. By Congress.

No Puerto Rican was consulted. No Puerto Rican was present at the negotiations. No plebiscite was held. An island that had just achieved self-governance was signed over from one empire to another like a deed to a house. The Autonomous Charter, the parliament, the cabinet — all of it became legally meaningless the moment the treaty was ratified.

Military Government

What replaced autonomy was military dictatorship. General Orders No. 101, issued by the War Department on July 18, 1898, established the legal framework: military governors would administer all civil affairs with the force of law, issue decrees restructuring local institutions, and prepare territories for annexation. The first military governor, General John R. Brooke, was followed by General Guy V. Henry, whose most consequential act was dissolving the Autonomic Cabinet on February 6, 1899. With a single order, he ended the self-governing institutions Puerto Ricans had fought decades to achieve.

The military government replaced Spanish courts with provost courts — military tribunals run by officers who spoke no Spanish, conducting summary justice without jury trials, due process, or appeal rights. Puerto Ricans were prosecuted under military law for civilian offenses. The legal system that replaced Spanish colonial law was not democracy. It was martial law with paperwork.

The 40% Theft

One of the military government's first economic acts was the forced conversion of Puerto Rican currency. The Puerto Rican peso, which had traded near parity with the U.S. dollar, was converted at a rate of 60 cents to the peso.⁵ Overnight, every Puerto Rican's savings, wages, and debts lost 40% of their value. Mortgages remained at their original peso amounts but now had to be repaid in more expensive dollars. Small farmers who could no longer make payments lost their land. American corporations, arriving with dollars, bought that land at fire-sale prices. The currency devaluation was not an accident. It was the first systematic transfer of Puerto Rican wealth to American interests.

The full picture, however, requires a qualification. The Puerto Rican peso had already been trading at a discount to the U.S. dollar before the forced conversion — the 40% figure assumes a one-to-one baseline that did not exist in practice. The actual loss varied depending on what exchange rate individual holders had been experiencing. This does not diminish the fact that the conversion resulted in significant losses for Puerto Rican savers and created conditions for dispossession, but the precise magnitude of the theft was somewhat less uniform than a flat 40% figure suggests.

San Ciriaco

On August 8, 1899 — one year after the invasion — Hurricane San Ciriaco struck Puerto Rico. It was one of the deadliest hurricanes in the island's history. Approximately 3,400 people died.⁶ The storm destroyed the coffee industry, which had been the island's most valuable export and the economic backbone of the mountainous interior. Coffee farms in Utuado, Adjuntas, Lares, and Jayuya were devastated. The haciendas that had supported the creole middle class were wiped out.

The U.S. military government's response was revealing. Relief was minimal. What resources were directed went to sugar production, not coffee recovery. The hurricane accomplished by wind what the currency devaluation accomplished by policy: it cleared the way for American sugar corporations to buy up ruined land. Within a decade, four American corporations would control more sugar acreage than all Puerto Rican farmers combined. The hurricane was natural. The response was colonial.

The New Order

By 1900, the outlines of the new colonialism were clear. English was imposed in public schools as the language of instruction — a policy that would persist, with variations, for fifty years. Teachers who refused were fired. Students who couldn't learn in a language they didn't speak were classified as failures. The Americanization of the schools was not about education. It was about erasure.

On April 12, 1900, President McKinley signed the Foraker Act, replacing military government with a civilian colonial government.⁷ It was progress — from dictatorship to managed colonialism. But the Foraker Act gave Puerto Ricans almost nothing: the governor was appointed by the U.S. President, the Executive Council (upper house) was appointed by the President, and Puerto Rico received a single non-voting Resident Commissioner in Congress. A voice without a vote. The Puerto Rican people would not elect their own governor until 1948 — fifty years later.

The Foraker Act also established free trade between Puerto Rico and the United States, eliminating the tariffs that had existed under the previous regime. This commercial integration benefited Puerto Rican exporters — particularly sugar and tobacco producers — and laid the groundwork for the economic transformation that would reshape the island in the decades to come. The economic benefits were real, if unevenly distributed, and they contributed to binding Puerto Rico's economy to that of the United States in ways that would prove difficult to undo.

The Foraker Act also applied the cabotage laws — the maritime shipping regulations that required all goods shipped between U.S. ports to travel on U.S.-built, U.S.-flagged, U.S.-crewed ships.⁸ Puerto Rico, an island that imports most of its food and consumer goods, was locked into the most expensive shipping system in the Western Hemisphere. This law, later reinforced as the Jones Act, remains in effect today. Every gallon of milk, every car, every building material that arrives in Puerto Rico costs more because of a shipping monopoly established in 1900.

In two years, Puerto Rico went from self-governing nation to occupied territory. The autonomous parliament was dissolved. The currency was devalued. The courts were militarized. The schools were anglicized. The land was consolidated. The shipping was monopolized. And the people who had governed themselves — however briefly — were told that their political status would be determined by a Congress in which they had no vote. The colonial framework established between 1898 and 1900 would prove to be extraordinarily durable. Much of it remains in place today.
