Casimiro Barela (1847-1920) was an important figure in Colorado History. He was the longest-serving member of the Colorado Legislature (1876-1917) and helped to craft the Colorado Constitution, and certainly caused it to be printed in multiple languages.
Barela was born in the middle of the US-Mexico War in Embudo, Mexico, which would become New Mexico after the Treaty of Guadelupe Hidalgo. After helping his father to work as a cattle raiser, he returned to school and in 1867 moved to a ranch 20 miles outside Trinidad. He started his career there in 1867 as a Justice of the Peace at the age of 20, shortly after his marriage to Josefita Ortiz.
In 1876, he served in the Colorado Constitutional Convention, and then served in the Colorado Senate from 1876-1893, after which he served in the House from 1893-1917.
These books were published in 1886 and 1889, so Barela would have been in the Colorado Senate at the time.
