The state of Texas was once an independent country known as the Republic of Texas. It gained independence from Mexico in 1836 and was a separate nation until it was annexed by the United States in 1845.
San Jacinto County, Texas, is located in the southeastern part of the state. The area was originally inhabited by various Native American tribes, including the Atakapa, Akokisa, and Caddo peoples. In the early 19th century, European settlers began to arrive, with Stephen F. Austin's colony bringing the first wave of Anglo-Americans to the region.

The county was officially established in 1870, named after the Battle of San Jacinto, a turning point in the Texas Revolution. The battle took place in 1836, when Texan forces led by General Sam Houston defeated Mexican forces led by General Antonio López de Santa Anna. This victory led to the independence of Texas from Mexico.

San Jacinto County experienced significant growth in the late 19th century due to the expansion of the railroad in the region.
