Which of the following groups is associated with the early settlement of Texas?

The Old 300 refers to the original group of American families who settled in Texas under the invitation of Stephen F. Austin in the early 1820s. This group is significant because they were among the first Anglo settlers to establish a lasting presence in the region, which facilitated the growth of Texas as a colony. They received land grants to encourage settlement, and their arrival marked the beginning of significant demographic and cultural changes in Texas. The actions of the Old 300 laid the groundwork for the development of Texas as a key area in early American expansion toward the West.

In contrast, while the Filibusters were involved in attempts to incite rebellion and promote independence in various areas, their activities occurred later and were not focused solely on settlement. The Conquistadors were explorers and conquerors from Spain who arrived much earlier in the 16th century, primarily interested in conquest and resource extraction rather than settlement. The term Texians typically refers to settlers, particularly Anglo settlers and their descendants, during the Texas Revolution in the 1830s but does not encapsulate the early settlement period as accurately as the Old 300.
