LaSalle Parish, Louisiana: History
The parish was established (as the Parish of LaSalle) on July 3, 1908.
In 1908, when Catahoula Parish was split in half and formed LaSalle Parish an immediate struggle developed between the towns of Olla and Jena over the location of the parish courthouse and seat. Jena was subsequently chosen over Olla, the larger and more established community at the time, as the seat of government due to Jena's central location within the newly formed Parish.
