Étienne de Boré: The First Mayor and the Man Who Made Sugar King

The First Mayor and the Man Who Made Sugar King

Étienne de Boré was born on December 27, 1741, in Kaskaskia, in what is now Illinois. His parents sent him to France at age four for education, and he eventually served in the prestigious Musketeers of the Guard — the elite military corps of the French king. He married Marie Marguerite d'Estréhan in 1771 and received, as part of her dowry, a plantation about six miles north of New Orleans. That land would later become Audubon Park, Tulane University, and the Audubon Zoo.

The Sugar Revolution

In the 1790s, Louisiana's indigo crop was failing, and planters were desperate for a new cash crop. Boré took a gamble. In 1794, working with Antoine Morin — a free man of color from Saint-Domingue who brought expertise in chemistry and botany — Boré used that year's sugarcane to seed his 1795 crop. Together, they produced Louisiana's first granulated sugar.

The impact was seismic. Sugar production transformed Louisiana's economy virtually overnight. Planters who had been going broke on indigo switched to sugarcane and made fortunes. Sugar became the engine of the plantation economy, the source of New Orleans' wealth, and the foundation of a culture that would define the region for the next century. All of it traces back to Boré's plantation and Morin's chemistry.

First Mayor of New Orleans

After the Louisiana Purchase in 1803, Boré was appointed the first mayor of New Orleans under American administration — serving from December 1803 to May 1804. It was a brief tenure, but symbolically powerful: the man who had made Louisiana economically viable was now leading its most important city into a new era under a new flag.

Étienne de Boré died on February 1, 1820, at seventy-eight, and was buried in St. Louis Cemetery No. 1. His plantation became the park and university that anchor Uptown New Orleans today. A live oak in Audubon Park still bears his name — a tree that has stood longer than almost anything else in the city, just like the sugar industry he created.
