Who is known for his victory at San Jacinto and became the first President of the Republic of Texas?

• A. James K. Polk
• B. Sam Houston
• C. Stephen F. Austin
• D. John Tyler

Answer: (B)

The individual recognized for his significant victory at the Battle of San Jacinto is Sam Houston. This battle, fought on April 21, 1836, was a decisive engagement in the Texas Revolution, leading to Texas gaining independence from Mexico. After this remarkable military achievement, Houston was elected as the first President of the Republic of Texas in 1836, solidifying his role as a key figure in Texas history.

The other individuals listed do have their own notable historical contributions but do not relate directly to the specific achievement of winning at San Jacinto and becoming the first President of Texas. James K. Polk was a prominent political figure and later served as President of the United States, but he was not involved in the Texas Revolution as a military leader. Stephen F. Austin is often called the "Father of Texas" due to his early efforts in colonizing the area, but he was not a military commander at San Jacinto. John Tyler, while involved in the annexation of Texas as President, did not play a role in the battle or in establishing the Republic's presidency. Thus, Sam Houston is the correct answer based on his direct involvement and historical significance related to this particular event.
