The founding of the Popular Democratic Party

The party that would eventually design the 1952 Free Associated State arrangement began, ten years earlier, as a breakaway faction of disillusioned liberals and former socialists, with no guarantee it would survive its first decade.

The Popular Democratic Party was founded in 1938 by dissidents expelled from the Liberal Party of Puerto Rico, then led by Antonio R. Barceló. Many of its founders had roots in the island's older socialist movement, bringing a distinct political tradition to the new party from the start.

The break traced back to a 1937 disagreement over strategy. Barceló's faction favored a moderate, gradual approach to autonomy that could lead over time to independence. The dissidents, led by Luis Muñoz Marín, wanted more immediate independence and social reform, and were unwilling to wait for a slower path.

Jesús T. Piñero, who would later become the first Puerto Rican-born appointed governor, was one of the PPD's original founders, giving the new party an early figure who would go on to hold real executive power.

At first, the party's fortunes were genuinely uncertain. In the 1940 election it tied with the Liberal Party, and Muñoz Marín had to piece together a coalition with minor parties just to secure the presidency of the Puerto Rican Senate, at the time the island's highest elected office, since the governor was still appointed and not elected.

That uncertain start did not last. The PPD's margins grew strongly in the 1944 and 1948 elections, and by 1948 it was winning nearly every legislative and municipal race on the island. That same PPD-controlled Senate would pass, that very year, the controversial Gag Law, a complicated legacy for a party that at once built the island's modern democratic institutions and moved to repress its own independence movement.
