Land grant on the Rio Grande lays foundation of El Paso, Texas

Background. Prior to 1827, most settlement in the region was south of the Rio Grande, where modern Mexico lies. The area was known as El Paso del Norte. The north bank remained largely undeveloped until the establishment of the first permanent agricultural enterprise and residence by Juan Maria Ponce de Leon.

Establishment of Rancho Ponce. Juan Maria Ponce de Leon, a wealthy merchant from Paso del Norte, built the region's first structure on the north bank of the Rio Grande in 1827. This action established Rancho Ponce, marking the start of permanent settlement on the north bank of the Rio Grande, an area that was then part of the Mexican state of Chihuahua and later became part of El Paso, Texas.

Foundational Significance. The construction of the first residence and the associated land grant are cited as foundational events for modern El Paso, Texas. Although the exact acreage and grant details vary between sources, the establishment of Rancho Ponce is recognized as the beginning of permanent development north of the river.
