?
spanish colonization
texas revolution
exploration and early colonization
mexican national era
government

Explanation:

The sequence seems to be following a historical - chronological order of events related to Texas. After the natural state of Texas and its people, the next logical historical phase before Spanish colonization is the period of exploration and early settlement attempts. The Texas Revolution came after Spanish and Mexican rule, the Mexican National Era was after Spanish colonization, and 'Government' is too general in this context.

Answer:

Exploration and Early Colonization
