Muenster, Texas, in Cooke County, began in 1889 through efforts of German-American colonizing entrepreneurs who attracted settlers from other German-American colonies in the United States. The community, founded on the premise of maintaining cultural purity, survived and prospered for a century by its reliance on crops, cattle, and oil. In its political conservatism and economic ties to the land, Muenster resembled its neighboring Anglo-American communities. Its Germanic heritage, however, became pronounced in the community's refusal to accommodate to the prohibitionism of North Texas regarding alcoholic beverages and in the parishioners' fidelity to the Roman Catholic faith. These characteristics are verified in unpublished manuscripts, governmental documents, local records, and interviews with Muenster residents.

Reacting to the Great Depression, Texans abandoned the philosophy of rugged individualism and turned to their state and federal governments for leadership. Texas's Governor Miriam Ferguson resultantly created the state's first relief agency, which administered all programs including those federally funded. Because the Roosevelt administration ordered state participation in and immediate implementation of the CCC, a multi-governmental, multi-departmental administrative alliance involving state and federal efforts resulted, which, because of scholars' preferences for research at the federal level, often is mistakenly described as a decentralized administration riddled with bureaucratic shortcomings. CCC operations within Texas, however, revealed that this complicated administrative structure embodied the reasons for the CCC's well-documented success.

Slavery was established in Texas with the first Anglo-American settlement in 1822. The constitution of the Republic of Texas protected slavery as did laws passed by the legislature from 1836 to 1846, and the institution of slavery grew throughout the period. Slaves were given adequate food, clothing, and shelter for survival, and they also managed to develop a separate culture. Masters believed that slaves received humane treatment but nevertheless worried constantly about runaways and slave revolts. The Republic's foreign relations and the annexation question were significantly affected by the institution of slavery. The most important primary sources are compilations of the laws of Texas, tax rolls, and traveler's accounts. The most informative secondary source is Abigail Curlee's unpublished doctoral dissertation, "A Study of Texas Slave Plantations, 1822 to 1865" written at the University of Texas in 1932.

This study examines the impact of the citizens of the La Reunion colony on the development of Dallas and Dallas County. The French, Belgian, and Swiss families that formed the utopian colony broughta blend of European culture and education to the Texas frontier in 1853. The founding of La Reunion and a record of its short existence is covered briefly in the first two chapters. The major part of the research, however, deals with the colonists who remained in Dallas County after the colony failed in 1856. Chapters three and four make use of city, county, and state records along with personal collections from the Dallas Historical Society Archives and the Dallas Public Library to examine the colonists effect on the government and business community. Chapter five explores the cultural development of the area through city and county records and personal collections.

The decade of the 1850s saw the Texas press separate into two opposing groups on the issue of filibustering. The basis for this division was the personal beliefs of the editors regarding the role filibustering should have in society. Although a lust for wealth drove most filibusters, the press justified territorial expansion along altruistic lines. By 1858, however, a few newspapers discarded this argument and condemned filibusters as lawless bands of ruffians plundering peaceful neighbors. Throughout the decade, the papers gradually drifted from a consensus in 1850 to discord by the date of William Walker's third attempt on Nicaragua in 1858.
