From a Spanish crossing on the Colorado to the third-oldest Anglo settlement in Texas, through the Civil War, the railroads, the 2011 fire, and the Austin-spillover present.
The land along this stretch of the Colorado River had been used by Tonkawa, Lipan Apache, and Comanche peoples for centuries before European contact. The El Camino Real de los Tejas — the Spanish royal road from Mexico to East Texas — crossed the Colorado River near present-day Bastrop, making this one of the earliest documented river crossings in Texas.
The town was founded in 1832 as part of Stephen F. Austin's colony, originally called Mina, after Mexican federalist Francisco Xavier Mina. After Texas independence, it was renamed Bastrop in honor of the Baron de Bastrop, who had helped Austin negotiate his original colonization grant. Bastrop is the third-oldest Anglo settlement in Texas and one of the original 23 counties of the Republic.
The town grew as a river port and timber-shipping hub. The Lost Pines made Bastrop a regional source of building lumber, and Bastrop pine was used in capitol buildings, courthouses, and homes across Central Texas. The 1882 arrival of the railroad accelerated growth and gave Smithville its identity as a rail division point.
The county sided with the Confederacy during the Civil War. Reconstruction, freedmen's settlements, and a slow agricultural recovery defined the late 19th century. Brick downtowns went up in the 1880s and 1890s — many of those buildings still stand today.
The Civilian Conservation Corps came to Bastrop in 1933 and built much of what is now Bastrop State Park — the headquarters, the swimming pool, the cabins, the road system. The CCC stonework is still in daily use and is on the National Register of Historic Places.
For most of the 20th century Bastrop County was rural — cotton, then cattle, then a quiet country-living shift in the 1970s and 80s as Austin began to grow and a few neighborhoods (Pine Forest, Tahitian Village, Circle D) were carved out of the forest.
On September 4, 2011, fueled by the worst drought in Texas history, the Bastrop County Complex Fire ignited. Over the next 32 days it burned 34,000 acres, destroyed 1,673 homes, and killed two people. It is still the most destructive wildfire in Texas history. Most of Bastrop State Park burned. The recovery has reshaped local politics, building codes, insurance markets, and forest management for more than a decade.
Since the late 2010s, Bastrop County has been one of the fastest-growing counties in Texas. Major employers have built or announced facilities along the Highway 71 / 130 Toll corridor, and the population has grown roughly 17% in the past four years. Newcomers, longtimers, ranchers, and tech workers now share a county that is, as much as any in Texas, in the middle of becoming something new.
