What was a key feature of Donation Grants issued in Texas?

The key feature of Donation Grants issued in Texas was that they were linked to service in specific battles. These grants were typically awarded as a form of reward or recognition for military service, particularly to soldiers who participated in significant conflicts, such as the Texas Revolution. This system was designed to encourage military participation and support settlement in Texas by granting land to those who had demonstrated their commitment through service.

In contrast, the other options do not accurately capture the essence of Donation Grants. While agricultural use was indeed a common purpose for land grants, they were not exclusively restricted to agricultural purposes. The limitation to veterans of the Civil War is also not specific to Donation Grants, as many veterans from different periods received land grants. Lastly, the requirement for immediate settlement on land does not define Donation Grants, as various types of land grants had different stipulations regarding settlement timelines.
