Who was the President of Mexico and the commander at the Alamo?

• A. Sam Houston
• B. Antonio Lopez de Santa Anna
• C. Marin de Cos
• D. Hendrick Arnold

Answer: (B)

Antonio López de Santa Anna fits because he was the President of Mexico and the commander of the Mexican forces during the siege of the Alamo in 1836. He led the troops who attacked the Texian defenders in San Antonio, making him the person who held both roles described in the question. The Texian leader who ultimately defeated Santa Anna at San Jacinto is different, and the other figures listed did not serve as both Mexican president and commander at the Alamo. The Alamo was a key event in the Texas Revolution, where Mexican forces led by Santa Anna overwhelmed the defenders, helping galvanize Texan resistance.
