Mathias Brugman
Born Louisiana USA,Puerto Rican activist (1811–1868)

Mathias Brugman (birth name: Mathias Brugman Duliebre) (January 3, 1811 – September 30, 1868), a.k.a. Mathias Bruckman, was a leader in Puerto Rico's independence revolution against Spain known as El Grito de Lares (English: The Cry of Lares).
Early years
Brugman's father was Pierre Brugman from Curaçao of Dutch–Jewish Sephardic ancestry and his mother, Isabel Duliebre from Puerto Rico. They met and married in New Orleans, Louisiana where Brugman was born, raised and educated.
The Brugman family moved to Puerto Rico and settled in the City of Mayagüez where Mathias met and married Ana Maria Laborde. He opened a colmado (grocery store) and became rather successful, only to lose a good part of his fortune attempting to grow coffee. Like many other residents of Puerto Rico at the time, he resented the political injustices practiced by Spain on the island. This led him to become a believer in the cause of the Puerto Rican independence movement.
Independence advocate
Brugman admired independence advocates Ramón Emeterio Betances and Segundo Ruiz Belvis. It was this admiration which inspired him to become an outspoken advocate for Puerto Rico's independence.

Why this record matters
The phrase “born Louisiana USA,Puerto Rican activist (1811–1868)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 17, 2026. The linked authority identifier is Q1908439. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1811 and 1868.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
