Q. What do you mean by militant nationalism ? 

Militant nationalism arose in Europe in the latter part of the 19^th century. It meant outright wars by the European countries to achieve their goals. Militant nationalism included two main features: first, the mechanism of maintaining great large standing armies and navies. This was accompanied by espionage, suspicion, fear and hatred, etc. Second, the existence of a powerful class of military and naval officers, headed by staff, who tended to dominate, especially at a time of political crisis, over the civilian authorities. Militant nationalism was caused by aggressive nationalism, economic competition and international tension.
