Sila María Calderón (born September 23, 1942) made history in 2001 by becoming the first woman ever to become Governor of Puerto Rico after winning the 2000 elections.

Calderón is ex-President of the Popular Democratic Party, or PPD.

Calderón was also mayor of the city of San Juan from 1996 to 2000.

During her campaign for Governor, Calderón was accused of abusive treatment by one of her former house workers. Soon it was discovered, however, that the accuser had been paid off by her opponents.

Calderón divorced her long-time husband Adolfo Krans, soon after her election. She has basically kept her public life to her work as governor ever since, and hasn't been known for personal scandals.

During her period as governor, crime has risen in Puerto Rico, although not by much. This could also be attributed, however, to a lax effort by the people she has chosen as police superintendents in the island. Although she travels to Washington D.C often, she is not known for being a governor who travels internationally a lot. Instead of becoming a pusher for international firms to invest in Puerto Rico, like some past governors have done, she has concentrated her battle mostly on the domestic side, with issues like Vieques and the fight against drugs.

Calderón has announced she will not run for re-election at the 2004 Puerto Rican elections.

She married Ramón Cantero Frau on September 10, 2003. It was be the first time a Puerto Rican governor gets married during leadership. It also marked the first time a wedding ceremony is carried at La Fortaleza, Puerto Rico's governor's official residence. The ceremony was transmitted live across Puerto Rico and the United States.
