in Central Texas. Settlement in the area began to expand quickly. Travis County was established in 1840, and the surrounding counties were mostly established within the next two decades. Initially, the new capital thrived but Lamar's political enemy, Sam Houston, used two Mexican army incursions to San Antonio as an excuse to move the government. Sam Houston fought bitterly against Lamar's decision to establish the capital in such a remote wilderness. The men and women who traveled mainly from Houston to conduct government business were intensely disappointed as well. By 1840, the population had risen to 856, nearly half of whom fled Austin when Congress recessed. The resident African American population listed in January of this same year was 176. The fear of Austin's proximity to the Indians and Mexico, which still considered Texas a part of their land, created an immense motive for Sam Houston, the first and third President of the Republic of Texas, to relocate the capital once again in 1841. Upon threats of Mexican troops in Texas, Houston raided the Land Office to transfer all official documents to Houston for safe keeping in what was later known as the Archive War, but the people of Austin would not allow this unaccompanied decision to be executed. The documents stayed, but the capital would temporarily move from Austin to Houston to Washington-on-the-Brazos. Without the governmental body, Austin's population declined to a low of only a few hundred people throughout the early 1840s. The voting by the fourth President of the Republic, Anson Jones, and Congress, who reconvened in Austin in 1845, settled the issue to keep Austin the seat of government, as well as annex the Republic of Texas into the United States. In 1860, 38% of Travis County residents were slaves. In 1861, with the outbreak of the American Civil War, voters in Austin and other Central Texas communities voted against secession. However, as the war progressed and fears of attack by Union forces increased, Austin contributed hundreds of men to the Confederate forces. The African American population of Austin swelled dramatically after the enforcement of the Emancipation Proclamation in Texas by Union General Gordon Granger at Galveston, in an event commemorated as Juneteenth. Black communities such as Wheatville, Pleasant Hill, and Clarksville were established, with Clarksville being the oldest surviving freedomtown ‒ the original post-Civil War settlements founded by former African-American slaves ‒ west of the
