I want to know the answer to the following question:
Which political forces maintained strong control over the state until shortly after French intervention?
All the background I'm provided with is that "President Juárez, in an effort to organize a strong defense against the French, decreed a list of national guard units that every state had to contribute to the Ministry of War and the Navy; Chihuahua was responsible for inducting 2,000 men.". Is that enough to answer the question?
Answer: no
