Los Angeles
On the 4th of September 1781, a group of forty-four settlers known as Los Pobladores founded the town they called El Pueblo de Nuestra Señora la Reina de los Ángeles del Río Porciúncula. This settlement rose from the village of Yaanga, which held deep meaning for the indigenous Tongva people who had inhabited the region for centuries before Spanish arrival. The name Yaanga translates to place of the poison oak or valley of smoke in the Tongva language. Spanish explorer Juan Rodríguez Cabrillo claimed the area for Spain in 1542 while moving northward along the Pacific coast. Franciscan friar Junípero Serra directed the building of Mission San Gabriel Arcángel in 1771, establishing the first mission in the area. By 1820, the population had grown to about six hundred fifty residents despite remaining a small ranch town for decades. The pueblo became part of the First Mexican Empire in 1821 following the Mexican War of Independence. Governor Pío Pico made Los Angeles the regional capital of Alta California during Mexican rule. Marines from the United States occupied the pueblo in 1846 during the wider Mexican, American War. A siege ensued where one hundred fifty Mexican militias fought the occupiers until surrender. American Conquest of California culminated with the signing of the Treaty of Cahuenga on the 13th of January 1847.

Residential zones prohibited barns, lumber yards, and machine-powered equipment industrial uses initially. Seven industrial zones designated later allowed exceptions between 1908 and 1915 despite broad proscriptions. Interstate Highway System expansion during the 1950s and 1960s propelled suburban growth while signaling demise of privately owned electrified rail systems once called the world largest.
