Who held the role of Commandant of the Marine Corps from 1820 to 1859?

• A. Jacob Zeilin
• B. John A. Lejeune
• C. Archibald Henderson
• D. Charles Wilkins

Answer: (C)

Archibald Henderson is the person who fits that time span. He became Commandant in 1820 and served until 1859, the longest tenure in Marine Corps history. That extended leadership allowed him to transform the force into a more professional, disciplined organization by standardizing training and drill, improving officer and NCO development, and expanding the Corps’ capabilities. Because his command covers the entire period from 1820 through 1859, he is the right answer for who held the role during those years. The other names served at different times, so they don’t match the 1820–1859 window.
