History

The area that is now Wilmington was inhabited by the Tongva people of Native Americans. Archeological work in the nearby Chowigna excavation show evidence of inhabitants as far back as 7,100 years ago.

The Spanish Empire expanded into this area when the Viceroy of New Spain commissioned Juan Rodríguez Cabrillo to explore the Pacific Ocean in 1542–1543. In 1784, the Spanish Crown deeded Rancho San Pedro, a tract of over in the area, to retired soldier Juan José Domínguez, for his service with the Portolà expedition into the area over a decade earlier.

Phineas Banning acquired the land that would become Wilmington from Manuel Dominguez, grand nephew and heir to Juan José Domínguez, in 1858 to build a harbor for the city of Los Angeles. Known as New San Pedro from 1858 to 1863, it was subsequently renamed Wilmington by Banning, a.k.a. “Father of the Harbor”, after his birthplace, Wilmington, Delaware.

In 1861, at the beginning of the Civil War, Banning and Benjamin Wilson gave the federal government 60 acres of land to build Drum Barracks to protect the nascent Los Angeles harbor from Confederate attack.

Wilmington was a township in the 1870 census. The township consisted of the present-day South Bay communities, Compton, western Long Beach, parts of Rattlesnake Island and Mormon Island which later evolved into Terminal Island. Census records report a population of 942 in 1870. The township had been named San Pedro Township in 1860.

Wilson College, precursor to the University of Southern California, opened in Wilmington in 1874 as the first coeducational college west of the Mississippi.
