Most people living in Los Angeles today have probably never heard of the Expedition of 1781. However, if this expedition had not taken place or fulfilled its objectives, Los Angeles would not have turned 238 years old in September 2019. This expedition of almost a thousand miles founded a small pueblo on the outskirts of the extensive Spanish Empire. That small pueblo, now known as Los Angeles, would eventually form the nucleus of a thriving multi-ethnic, multicultural urban center with a population of almost 10 million people.
