Bastrop is a city in and the parish seat of Morehouse Parish, Louisiana.
Bastrop was founded by the Baron de Bastrop (born Felipe Enrique Neri), a Dutch embezzler who falsely claimed to be a nobleman. He had fled to the then Spanish colony of Louisiana to escape prosecution, and became involved in various land deals. He received a large grant of land, provided that he could settle 450 families on it over the next several years. However, he was unable to do this, and so lost the grant. Afterwards, he moved to Texas, where he claimed to oppose the sale of Louisiana to the United States, and became a minor government official. He proved instrumental in Moses Austin's plan (and later, that of his son, Stephen F. Austin) to bring American colonists to what was then northern Mexico.
Bastrop formally incorporated in 1857, and is the commercial and industrial center of Morehouse Parish. In the 19th century, it was notable as the western edge of the great north Louisiana swamp, but more favorable terrain resulted in the antebellum rail line connecting to Monroe, Louisiana, further to the south.
